RESULT_NS

public static String RESULT_NS
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
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
Since:
8.8

sendWrappedSequence

public static void sendWrappedSequence(SequenceIterator iterator,

                                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
Since:
8.8

serialize

public static void serialize(NodeInfo node,
                             Result destination,

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
