class PyDocumentBuilder(builtins.object) |
| |
A PyDocumentBuilder holds properties controlling how a Saxon document tree should be built, and
provides methods to invoke the tree construction.
This class has no public constructor. To construct a PyDocumentBuilder, use the factory method
PySaxonProcessor.new_document_builder().
|
| |
Methods defined here:
- __init__(...)
- Creates a new instance, keeping a reference to its PySaxonProcessor
:param processor:
- __reduce__ = __reduce_cython__(...)
- __setstate__ = __setstate_cython__(...)
- get_schema_validator(...)
- get_schema_validator(self)
Get the PySchemaValidator used to validate documents loaded using this PyDocumentBuilder
Returns:
PySchemaValidator: if one has been set; otherwise None.
- parse_xml(...)
- parse_xml(self, **kwds)
Parse a source document supplied as a lexical representation, source file or uri, and return it as XDM node
Args:
**kwds: Possible keyword arguments: one of the following (xml_file_name|xml_text|xml_uri) is required.
The keyword 'encoding' (str) can be used to specify the encoding used to decode the xml_text string
(if not specified then the platform default encoding is used).
Returns:
PyXdmNode: The XDM node representation of the XML document
Raises:
Exception: Error if invalid use of keywords.
PySaxonApiError: Error if failure to parse XML file or XML text
- set_base_uri(...)
- set_base_uri(self, base_uri)
Set the base URI of a document loaded using this PyDocumentBuilder. This is used for resolving any relative
URIs appearing within the document, for example in references to DTDs and external entities. This information
is required when the document is loaded from a source that does not provide an intrinsic URI, notably when
loading from a String. The value is ignored when loading from a source that does have an intrinsic base URI.
Args:
base_uri (str): the base output URI
- set_dtd_validation(...)
- set_dtd_validation(self, value)
Set whether DTD validation should be applied to documents loaded using this PyDocumentBuilder.
By default, no DTD validation takes place.
Args:
value (bool): true if DTD validation should be applied to loaded documents
- set_line_numbering(...)
- set_line_numbering(self, value)
Set whether line and column numbering and is to be enabled for documents constructed using this
PyDocumentBuilder. By default, line and column numbering is disabled.
Args:
value (bool): true if line numbers are to be maintained, false otherwise
- set_schema_validator(...)
- set_schema_validator(self, PySchemaValidator val)
Set the PySchemaValidator to be used. This determines whether schema validation is applied to an input
document and whether type annotations in a supplied document are retained. If no PySchemaValidator is supplied,
then schema validation does not take place.
This option requires the schema-aware version of the Saxon product (SaxonC-EE).
Since a PySchemaValidator is serially reusable but not thread-safe, using this method is not appropriate when
the PyDocumentBuilder is shared between threads.
Args:
val (PySchemaValidator): the schema validator to be used
Static methods defined here:

- Create and return a new object. See help(type) for accurate signature.
Data descriptors defined here:
- base_uri
- base_uri(self)
Get the base URI of documents loaded using this PyDocumentBuilder when no other URI is available.
Returns:
str: String value of the base URI to be used. This may be NULL if no value has been set.
- dtd_validation
- dtd_validation(self)
bool: Ask whether DTD validation is to be applied to documents loaded using this PyDocumentBuilder
- line_numbering
- line_numbering(self)
bool: true if line numbering is enabled

- declare_namespace(...)
- declare_namespace(self, prefix, uri)
Declare a namespace binding as part of the static context for XPath expressions compiled using this processor
Args:
prefix (str): The namespace prefix. If the value is a zero-length string, this method sets the default
namespace for elements and types.
uri (uri): The namespace URI. It is possible to specify a zero-length string to "undeclare" a namespace;
in this case the prefix will not be available for use, except in the case where the prefix is also a
zero length string, in which case the absence of a prefix implies that the name is in no namespace.
- declare_variable(...)
- declare_variable(self, str name)
Declare a variable as part of the static context for XPath expressions compiled using this processor.
It is an error for the XPath expression to refer to a variable unless it has been declared. This method
declares the existence of the variable, but it does not bind any value to the variable; that is done later,
when the XPath expression is evaluated. The variable is allowed to have any type (that is, the required
type is item()*).
Args:
name (str): The name of the variable, as a string in clark notation
- effective_boolean_value(...)
- effective_boolean_value(self, xpath_str)
Evaluate the XPath expression, returning the effective boolean value of the result.

- evaluate(self, xpath_str)
Evaluate an XPath expression supplied as a string
Args:
xpath_str (str): The XPath expression supplied as a string
encoding (str): The encoding of the XPath string. Argument can be omitted or None.

Evaluate an XPath expression supplied as a string, returning a single item
Args:
xpath_str (str): The XPath expression supplied as a string
encoding (str): The encoding of the XPath string. Argument can be omitted or None.
If not specified then the platform default encoding is used.
Returns:
PyXdmItem: A single XDM item is returned. Returns None if the expression returns an empty sequence.
If the expression returns a sequence of more than one item, any items after the first are ignored.
Raises:
PySaxonApiError: Error if failure to evaluate XPath expression
- exception_clear(...)
- exception_clear(self)
Clear any exception thrown
- import_schema_namespace(...)

- set_base_uri(self, base_uri)
Set the static base URI for XPath expressions compiled using this XPathCompiler.
The base URI is part of the static context, and is used to resolve any relative URIs appearing within an XPath
expression, for example a relative URI passed as an argument to the doc() function. If no
static base URI is supplied, then the current working directory is used.
Args:
base_uri (str): the base output URI
- set_caching(...)
- set_caching(self, is_caching)
Say whether the compiler should maintain a cache of compiled expressions.
Args:
is_caching (bool): if set to true, caching of compiled expressions is enabled.
If set to false, any existing cache is cleared, and future compiled expressions
will not be cached until caching is re-enabled. The cache is also cleared
(but without disabling future caching) if any method is called that changes the
static context for compiling expressions, for example declare_variable() or
declare_namespace().
- set_context(...)
- set_context(self, **kwds)
Set the initial context for the XPath expression
Args:
**kwds: Possible keyword arguments: file_name (str) or xdm_item (PyXdmItem)

- __reduce__ = __reduce_cython__(...)
- __setstate__ = __setstate_cython__(...)
- clear_parameters(...)
- clear_parameter(self)
Clear all parameters set on the processor for execution of the stylesheet
- compile_stylesheet(...)
- compile_stylesheet(self, **kwds)
Compile a stylesheet received as text, uri, as a node object, or as referenced in a specified XML document
via the xml-stylesheet processing instruction. The term "compile" here indicates that the stylesheet is
converted into an executable form. The compilation uses a snapshot of the properties of the PyXslt30Processor
at the time this method is invoked. It is also possible to save the compiled stylesheet (SEF file) given the
options 'save' and 'output_file'.
Args:
**kwds: Possible keyword arguments: one of stylesheet_text (str), stylesheet_file (str),
associated_file (str) or stylesheet_node (PyXdmNode); save (bool) and output_file (str) can be used
to save the exported stylesheet (SEF) to file; lang (str) can be used to set the XSLT (and XPath)
language level to be supported by the processor (possible values: '3.0' and '4.0');
fast_compile (bool) which requests fast compilation.
The following additional keywords can be used with 'save': target (str) which sets the target edition
under which the compiled stylesheet will be executed; and relocate (bool) which says whether the
compiled stylesheet can be deployed to a different location, with a different base URI.
The keyword 'encoding' (str) can be used with stylesheet_text to specify the encoding used to decode
the string (if not specified then the platform default encoding is used).
Returns:
PyXsltExecutable: which represents the compiled stylesheet. The PyXsltExecutable is immutable
and thread-safe; it may be used to run multiple transformations, in series or concurrently.
Raises:
PySaxonApiError: Error raised if the stylesheet contains static errors or if it cannot be read.
Example:
xsltproc = saxon_proc.new_xslt30_processor()
1) executable = xsltproc.compile_stylesheet(stylesheet_text="<xsl:stylesheet xmlns:xsl='http://www.w3.org/1999/XSL/Transform' version='2.0'>
<xsl:param name='values' select='(2,3,4)' /><xsl:output method='xml' indent='yes' />
<xsl:template match='*'><output><xsl:value-of select='//person[1]'/>
<xsl:for-each select='$values' >
<out><xsl:value-of select='. * 3'/></out>
</xsl:for-each></output></xsl:template></xsl:stylesheet>")
2) executable = xsltproc.compile_stylesheet(stylesheet_file="test1.xsl", save=True, output_file="test1.sef", target="HE")
3) executable = xsltproc.compile_stylesheet(associated_file="foo.xml")
- exception_clear(...)
- exception_clear(self)
Clear any exception thrown
- get_parameter(...)
- get_parameter(self, name, encoding=None)
Get a parameter value by a given name
Args:
name (str): The name of the stylesheet parameter
encoding (str): The encoding of the name string. If not specified then the platform default encoding is used.
Returns:
PyXdmValue: The XDM value of the parameter
- import_package(...)
- import_package(self, package_file_name)
Import a library package. Calling this method makes the supplied package available for reference
in the xsl:use-package declarations of subsequent compilations performed using this Xslt30Processor.
Args:
package_file_name (str): the file name of the package to be imported, which should be supplied
as an SEF. If relative, the file name of the SEF is resolved against the cwd, which is set
using the set_cwd method.
Example:
xsltproc = saxon_proc.new_xslt30_processor()
xsltproc.import_package('test-package-001.pack')
executable = xsltproc.compile_stylesheet(stylesheet_file="foo.xsl")
- remove_parameter(...)
- remove_parameter(self, name, encoding=None)
Remove the parameter given by name from the PyXslt30Processor. The parameter will not have any effect on the
stylesheet if it has not yet been executed.
Args:
name (str): The name of the stylesheet parameter
encoding (str): The encoding of the name string. If not specified then the platform default encoding is used.
Returns:
bool: True if the removal of the parameter has been successful, False otherwise.
- set_cwd(...)
- set_cwd(self, cwd)
Set the current working directory.
Args:
cwd (str): current working directory
- set_jit_compilation(...)
- set_jit_compilation(self, bool jit)
Say whether just-in-time compilation of template rules should be used.
Args:
jit (bool): True if just-in-time compilation is to be enabled. With this option enabled,
static analysis of a template rule is deferred until the first time that the
template is matched. This can improve performance when many template
rules are rarely used during the course of a particular transformation; however,
it means that static errors in the stylesheet will not necessarily cause the
compile(Source) method to throw an exception (errors in code that is
actually executed will still be notified but this may happen after the compile(Source)
method returns). This option is enabled by default in SaxonC-EE, and is not available
in SaxonC-HE or SaxonC-PE.
Recommendation: disable this option unless you are confident that the
stylesheet you are compiling is error-free.
- set_parameter(...)
- set_parameter(self, name, PyXdmValue value, encoding = None)

Args:
name (str): the name of the stylesheet parameter, as a string. For a namespaced parameter use
clark notation {uri}local
value (PyXdmValue): the value of the stylesheet parameter, or NULL to clear a previously set value
encoding (str): The encoding of the name string. If not specified then the platform default encoding is used.

Returns:
PyXsltExecutable: copy of this object

distribution and reloading.
Args:
file_name (str): The name of the file where the compiled stylesheet is to be saved
- get_initial_template_parameters(...)
- Returns the currently set dictionary of either tunneling or non-tunneling initial template parameters.
Any changes you make to the dictionary WILL NOT be reflected in the processor. This is a read-only view of
the parameters.
Args:

False if they are to be used for non-tunnel parameters. The default is false.
Returns:
(dict) the parameters dictionary

Get a parameter value by a given name
Args:
name (str): The name of the stylesheet parameter
Returns:
PyXdmValue: The XDM value of the parameter
- get_result_documents(...)

Return the secondary result documents resulting from the execution of the stylesheet. Null is
returned if the user has not enabled this feature via the method set_capture_result_documents.
Returns:
dict [str, PyXdmValue]: Dict of the key-value pairs. Indexed by the absolute URI of each result
document, and the corresponding value is a PyXdmValue object containing the result document (as
an in-memory tree, without serialization).
- get_xsl_messages(...)

Get the messages written using the xsl:message instruction. Return NULL if the user has not
enabled capturing of xsl:messages via the method set_save_xsl_message.
:return: value (PyXdmValue):
- remove_parameter(...)
- remove_parameter(self, name)
Remove the parameter given by name from the PyXslt30Processor. The parameter will not have any effect on the
stylesheet if it has not yet been executed.
Args:
name (str): The name of the stylesheet parameter
Returns:
bool: True if the removal of the parameter has been successful, False otherwise.
- set_base_output_uri(...)
- set_base_output_uri(self, base_uri)
Set the base output URI. The default is the base URI of the principal output
of the transformation. If a base output URI is supplied using this function then
it takes precedence over any base URI defined in the principal output, and
it may cause the base URI of the principal output to be modified in situ.
The base output URI is used for resolving relative URIs in the 'href' attribute
of the xsl:result-document instruction; it is accessible to XSLT stylesheet
code using the XPath current-output-uri() function.
Args:
base_uri (str): the base output URI
- set_capture_result_documents(...)
- set_capture_result_documents(self, bool value, bool raw_result)
Enable the capture of the result document output into a dict. This overrides the default mechanism.
If this option is enabled, then any document created using xsl:result-document is saved (as a PyXdmNode)
in a dict object where it is accessible using the URI as a key. After the execution of the transformation
a call on the get_result_documents method is required to get access to the result documents in the map.
It is also possible to capture the result document as a raw result directly as a PyXdmValue, without
constructing an XML tree, and without serialization. It corresponds to the serialization.
Args:
value (bool): true causes secondary result documents from the transformation to be saved in a map;
false disables this option.
raw_result (bool): true enables the handling of raw destination for result documents. If not supplied
this can also be set on the set_result_as_raw_value method. The set_result_as_raw_value method
has higher priority to this flag.
- set_cwd(...)
- set_cwd(self, cwd)
Set the current working directory.
Args:
cwd (str): current working directory
- set_global_context_item(...)

- set_initial_match_selection(self, **kwds)
The initial value to which templates are to be applied (equivalent to the select attribute of
xsl:apply-templates).
Args:
**kwds: Possible keyword arguments: must be one of the following (file_name|xdm_value)
Raises:
Exception: Exception is raised if keyword argument is not one of file_name or xdm_value
(providing a PyXdmValue).
- set_initial_mode(...)
- set_initial_mode(self, name)
Set the initial mode for the transformation
Args:
name (str): the EQName of the initial mode. Two special values are recognized, in the
reserved XSLT namespace:
xsl:unnamed to indicate the mode with no name, and xsl:default to indicate the
mode defined in the stylesheet header as the default mode.
The value null also indicates the default mode (which defaults to the unnamed
mode, but can be set differently in an XSLT 3.0 stylesheet).
- set_initial_template_parameters(...)
- set_initial_template_parameters(self, bool tunnel, dict parameters)
Set parameters to be passed to the initial template. These are used
whether the transformation is invoked by applying templates to an initial source item,
or by invoking a named template. The parameters in question are the xsl:param elements
appearing as children of the xsl:template element.
Args:
tunnel (bool): True if these values are to be used for setting tunnel parameters;
False if they are to be used for non-tunnel parameters. The default is false.
parameters (dict): the parameters to be used for the initial template supplied as key-value pairs.
Example:
1) paramArr = {'a':saxonproc.make_integer_value(12), 'b':saxonproc.make_integer_value(5)}

executable.transform_to_file(output_file="result.xml", xdm_node= node)
- transform_to_string(...)
- transform_to_string(self, **kwds)
Execute a transformation and return the result as a string.
Args:
**kwds: Possible keyword arguments: one of source_file (str) or xdm_node (PyXdmNode);
base_output_uri (str) which is used for resolving relative URIs
in the href attribute of the xsl:result-document instruction.
Also accept the keyword 'encoding' (str) to specify the encoding of the output string. This must
match the encoding specified by xsl:output in the stylesheet, or as specified using set_property()
on this PyXsltExecutable. If not specified then the platform default encoding is used.
Raises:
PySaxonApiError: Error raised in the event of a dynamic error
Example:
executable = xslt30_proc.compile_stylesheet(stylesheet_file="test1.xsl")
1) result = executable.transform_to_string(source_file="cat.xml")
2) executable.set_initial_match_selection(file_name="cat.xml")
result = executable.transform_to_string()
3) node = saxon_proc.parse_xml(xml_text="<in/>")
result = executable.transform_to_string(xdm_node= node)
- transform_to_value(...)
- transform_to_value(self, **kwds)
Execute a transformation and return the result as a PyXdmValue object.
Args:
**kwds: Possible keyword arguments: source_file (str) or xdm_node (PyXdmNode);
and base_output_uri (str) which is used for resolving relative URIs in the href attribute
of the xsl:result-document instruction.
Returns:
PyXdmValue: Result of the transformation as a PyXdmValue object
Raises:
PySaxonApiError: Error raised in the event of a dynamic error
Example:
xslt30_proc = saxon_proc.new_xslt30_processor()
executable = xslt30_proc.compile_stylesheet(stylesheet_file="test1.xsl")
1) result = executable.transform_to_value(source_file="cat.xml")
2) executable.set_initial_match_selection("cat.xml")
result = executable.transform_to_value()
3) node = saxon_proc.parse_xml(xml_text="<in/>")
result = executable.transform_to_value(xdm_node= node)
Static methods defined here:
- __new__(*args, **kwargs) from builtins.type
- Create and return a new object. See help(type) for accurate signature.
Data descriptors defined here:
- error_message
- error_message(self)
A transformation may have a number of errors reported against it. Get the error message if there are any errors
Returns:
str: The message of the exception. Returns None if the exception does not exist.
- exception_occurred
- exception_occurred(self)
Property to check for pending exceptions without creating a local reference to the exception object
Returns:
boolean: True when there is a pending exception; otherwise False
