Method Detail

serialize

public static String serialize(NodeInfo nodeInfo)
                        throws XPathException

Convenience method to serialize a node using default serialization options, placing the result in a string.

Parameters:

nodeInfo - the node to be serialized. This must not be an attribute or namespace node.

Returns:

the serialization of the node

Throws:

XPathException - if a serialization error occurs

Since:

9.0

wrap

public static DocumentInfo wrap(SequenceIterator iterator,
                Configuration config)
                         throws XPathException

Take the results of a query (or any other SequenceIterator) and create an XML document containing copies of all items in the sequence, each item wrapped in a containing element that identifies its type

Parameters:

iterator - The values to be wrapped

config - The Saxon configuration used to evaluate the query

Returns:

the document containing the wrapped results

Throws:

XPathException - if any failure occurs

Since:

8.8

sendWrappedSequence

public static void sendWrappedSequence(SequenceIterator iterator,
                       Receiver destination)
                                throws XPathException

Take a sequence supplied in the form of an iterator and generate a wrapped represention of the items in the sequence, the wrapped representation being a sequence of events sent to a supplied Receiver, in which each item is wrapped in a containing element that identifies its type

Parameters:

iterator - the input sequence

destination - the Receiver to accept the wrapped output

Throws:

XPathException - if a failure occurs processing the input iterator

Since:

8.8

serialize

public static void serialize(NodeInfo node,
             Result destination,
             Properties outputProperties,
             Configuration config)
                      throws XPathException

Deprecated. since 8.9; use serialize(NodeInfo, Result, Properties) instead.

Serialize a document containing wrapped query results (or any other document, in fact) as XML.

Parameters:

node - The document or element to be serialized

destination - The Result object to contain the serialized form

outputProperties - Serialization options, as defined in JAXP. The requested properties are not validated.

config - The Configuration. This argument is ignored

Throws:

XPathException - If serialization fails

serialize

public static void serialize(NodeInfo node,
             Result destination,
             Properties outputProperties)
                      throws XPathException

Serialize a document containing wrapped query results (or any other document, in fact) as XML.

Parameters:

node - The document or element to be serialized

destination - The Result object to contain the serialized form

outputProperties - Serialization options as defined in JAXP. The requested properties are not validated.

Throws:

XPathException - If serialization fails

Since:

8.9

serializeSequence

public static void serializeSequence(SequenceIterator iterator,
                     Configuration config,
                     OutputStream destination,
                     Properties outputProps)
                              throws XPathException

Serialize an arbitrary sequence, without any special wrapping.

Parameters:

iterator - the sequence to be serialized

config - the configuration (gives access to information such as the NamePool)

destination - the output stream to which the output is to be written

outputProps - a set of serialization properties as defined in JAXP. The requested properties are not validated.

Throws:

XPathException - if any failure occurs

Since:

8.9

public static void serializeSequence(SequenceIterator iterator,
                     Configuration config,
                     Writer writer,
                     Properties outputProps)
                              throws XPathException

Serialize an arbitrary sequence, without any special wrapping.

Parameters:

iterator - the sequence to be serialized

config - the configuration (gives access to information such as the NamePool)

writer - the writer to which the output is to be written

                              throws XPathException

Serialize a sequence to a given result

Parameters:

iterator - the sequence to be serialized

config - the Saxon Configuration

result - the destination to receive the output

outputProperties - the serialization properties to be used. The requested properties are not validated.

Throws:

XPathException - if any failure occurs

Since:

9.0

rewriteToDisk

public static void rewriteToDisk(NodeInfo doc,
                 Properties outputProperties,
                 boolean backup,
                 PrintStream log)
                          throws XPathException

Write an updated document back to disk, using the original URI from which it was read

Parameters:

doc - an updated document. Must be a document node, or a parentless element, or an element that has a document node as its parent. The document will be written to the URI found in the systemId property of this node.

outputProperties - serialization properties

backup - true if the old document at that location is to be copied to a backup file

log - destination for progress messages; if null, no progress messages are written

Throws:

XPathException - if the document has no known URI, if the URI is not a writable location, or if a serialization error occurs.
