Saxon.Api
Class XsltCompiler 

public class XsltCompiler
implements object

An XsltCompiler object allows XSLT 2.0 stylesheets to be compiled. The compiler holds information that represents the static context for the compilation.

To construct an XsltCompiler, use the factory method NewXsltCompiler on the Processor object.

An XsltCompiler may be used repeatedly to compile multiple queries. Any changes made to the XsltCompiler (that is, to the static context) do not affect queries that have already been compiled. An XsltCompiler may be used concurrently in multiple threads, but it should not then be modified once initialized.

Property Summary
 Uri BaseUri

The base URI of the stylesheet, which forms part of the static context of the stylesheet. This is used for resolving any relative URIs appearing within the stylesheet, for example in xsl:include and xsl:import declarations, in schema locations defined to xsl:import-schema, or as an argument to the document() or doc() function.

  XmlResolver

An XmlResolver, which will be used to resolve URI references while compiling a stylesheet

 bool SchemaAware

The SchemaAware property determines whether the stylesheet is schema-aware. By default, a stylesheet is schema-aware if it contains one or more xsl:import-schema declarations. This option allows a stylesheet to be marked as schema-aware even if it does not contain such a declaration.

 IList ErrorList

List of errors. The caller should supply an empty list before calling Compile; the processor will then populate the list with error information obtained during the compilation. Each error will be included as an object of type StaticError. If no error list is supplied by the caller, error information will be written to the standard error stream.

 
Method Summary
 XsltExecutable Compile(System.IO.Stream input)

Compile a stylesheet supplied as a Stream.

 XsltExecutable Compile(System.IO.TextReader input)

Compile a stylesheet supplied as a TextReader.

 XsltExecutable Compile(System.Uri uri)

Compile a stylesheet, retrieving the source using a URI.

 XsltExecutable Compile(System.Xml.XmlReader reader)

Compile a stylesheet, delivered using an XmlReader.

 XsltExecutable Compile(XdmNode node)

Compile a stylesheet, located at an XdmNode. This may be a document node whose child is an xsl:stylesheet or xsl:transform element, or it may be the xsl:stylesheet or xsl:transform element itself.

 XsltExecutable CompileAssociatedStylesheet(XdmNode source)

Locate and compile a stylesheet identified by an <?xml-stylesheet?> processing instruction within a source document.

 
Property Detail

BaseUri

public Uri BaseUri {get; set; }

The base URI of the stylesheet, which forms part of the static context of the stylesheet. This is used for resolving any relative URIs appearing within the stylesheet, for example in xsl:include and xsl:import declarations, in schema locations defined to xsl:import-schema, or as an argument to the document() or doc() function.

This base URI is used only if the input supplied to the Compile method does not provide its own base URI. It is therefore used on the version of the method that supplies input from a Stream. On the version that supplies input from an XmlReader, this base URI is used only if the XmlReader does not have its own base URI.

XmlResolver

public  XmlResolver {get; set; }

An XmlResolver, which will be used to resolve URI references while compiling a stylesheet

If no XmlResolver is set for the XsltCompiler, the XmlResolver is used that was set on the Processor at the time NewXsltCompiler was called.

SchemaAware

public bool SchemaAware {get; set; }

The SchemaAware property determines whether the stylesheet is schema-aware. By default, a stylesheet is schema-aware if it contains one or more xsl:import-schema declarations. This option allows a stylesheet to be marked as schema-aware even if it does not contain such a declaration.

If the stylesheet is not schema-aware, then schema-validated input documents will be rejected.

The reason for this option is that it is expensive to generate code that can handle typed input documents when they will never arise in practice.

The initial setting of this property is false, regardless of whether or not the Processor is schema-aware. Setting this property to true if the processor is not schema-aware will cause an Exception.

ErrorList

public IList ErrorList {get; set; }

List of errors. The caller should supply an empty list before calling Compile; the processor will then populate the list with error information obtained during the compilation. Each error will be included as an object of type StaticError. If no error list is supplied by the caller, error information will be written to the standard error stream.

By supplying a custom List with a user-written add() method, it is possible to intercept error conditions as they occur.

Method Detail

Compile

public XsltExecutable Compile(System.IO.Stream input)

Compile a stylesheet supplied as a Stream.

If the stylesheet contains any xsl:include or xsl:import declarations, then the BaseURI property must be set to allow these to be resolved.

The stylesheet is contained in the part of the input stream between its current position and the end of the stream. It is the caller's responsibility to close the input stream after use. If the compilation succeeded, then on exit the stream will be exhausted; if compilation failed, the current position of the stream on exit is undefined.

Parameters:
input -
A stream containing the source text of the stylesheet
returns
An XsltExecutable which represents the compiled stylesheet object. The XsltExecutable may be loaded as many times as required, in the same or a different thread. The XsltExecutable is not affected by any changes made to the XsltCompiler once it has been compiled.

Compile

public XsltExecutable Compile(System.IO.TextReader input)

Compile a stylesheet supplied as a TextReader.

If the stylesheet contains any xsl:include or xsl:import declarations, then the BaseURI property must be set to allow these to be resolved.

The stylesheet is contained in the part of the input stream between its current position and the end of the stream. It is the caller's responsibility to close the TextReader after use. If the compilation succeeded, then on exit the stream will be exhausted; if compilation failed, the current position of the stream on exit is undefined.

Parameters:
input -
A TextReader containing the source text of the stylesheet
returns
An XsltExecutable which represents the compiled stylesheet object. The XsltExecutable may be loaded as many times as required, in the same or a different thread. The XsltExecutable is not affected by any changes made to the XsltCompiler once it has been compiled.

Compile

public XsltExecutable Compile(System.Uri uri)

Compile a stylesheet, retrieving the source using a URI.

The document located via the URI is parsed using the System.Xml parser. This URI is used as the base URI of the stylesheet: the BaseUri property of the Compiler is ignored.

Parameters:
uri -
The URI identifying the location where the stylesheet document can be found
returns
An XsltExecutable which represents the compiled stylesheet object. The XsltExecutable may be run as many times as required, in the same or a different thread. The XsltExecutable is not affected by any changes made to the XsltCompiler once it has been compiled.

Compile

public XsltExecutable Compile(System.Xml.XmlReader reader)

Compile a stylesheet, delivered using an XmlReader.

The XmlReader is responsible for parsing the document; this method builds a tree representation of the document (in an internal Saxon format) and compiles it. The XmlReader will be used as supplied; it is the caller's responsibility to ensure that the settings of the XmlReader are consistent with the requirements of the XSLT specification (for example, that entity references are expanded and whitespace is preserved).

If the XmlReader has a BaseUri property, then that property determines the base URI of the stylesheet module, which is used when resolving any xsl:include or xsl:import declarations. If the XmlReader has no BaseUri property, then the BaseUri property of the Compiler is used instead. An ArgumentNullException is thrown if this property has not been supplied.

Parameters:
reader -
The XmlReader (that is, the XML parser) used to supply the document containing the principal stylesheet module.
returns
An XsltExecutable which represents the compiled stylesheet object. The XsltExecutable may be run as many times as required, in the same or a different thread. The XsltExecutable is not affected by any changes made to the XsltCompiler once it has been compiled.

Compile

public XsltExecutable Compile(XdmNode node)

Compile a stylesheet, located at an XdmNode. This may be a document node whose child is an xsl:stylesheet or xsl:transform element, or it may be the xsl:stylesheet or xsl:transform element itself.

Parameters:
node -
The document node or the outermost element node of the document containing the principal stylesheet module.
returns
An XsltExecutable which represents the compiled stylesheet object. The XsltExecutable may be run as many times as required, in the same or a different thread. The XsltExecutable is not affected by any changes made to the XsltCompiler once it has been compiled.

CompileAssociatedStylesheet

public XsltExecutable CompileAssociatedStylesheet(XdmNode source)

Locate and compile a stylesheet identified by an <?xml-stylesheet?> processing instruction within a source document.

There are some limitations in the current implementation. The media type is ignored, as are the other parameters of the xml-stylesheet instruction. The href attribute must either reference an embedded stylesheet within the same document or a non-embedded external stylesheet.

Parameters:
source -
The document node of the source document containing the xml-stylesheet processing instruction.
returns
An XsltExecutable which represents the compiled stylesheet object.
