Method Details

writeNodeToString

public static String writeNodeToString(Node node)

Writes the content of a DOM node to a String. An XML declaration is omitted.

Parameters:

node - The node to be serialized.

Returns:

A String representing the content of the given node.

writeNode

public static void writeNode(Node node,
 OutputStream outputStream)

Writes the content of a DOM node to a byte stream. An XML declaration is omitted.

Parameters:

node - The node to be serialized.

outputStream - The destination OutputStream reference.

transformToString

public static String transformToString(Source source)

evaluateXPath2

public static net.sf.saxon.s9api.XdmValue evaluateXPath2(Source xmlSource,
 String expr,
 Map<String,String> nsBindings)
                                                  throws net.sf.saxon.s9api.SaxonApiException

Evaluates an XPath 2.0 expression using the Saxon s9api API.

Parameters:

xmlSource - The XML Source.

expr - The XPath expression to be evaluated.

nsBindings - A collection of namespace bindings required to evaluate the XPath expression, where each entry maps a namespace URI (key) to a prefix (value); if the prefix is an empty string, it declares the default namespace.

Returns:

An XdmValue object representing a value in the XDM data model; this is a sequence of zero or more items, where each item is either an atomic value or a node.

Throws:

net.sf.saxon.s9api.SaxonApiException - If an error occurs while evaluating the expression; this always wraps some other underlying exception.

resultToString

public static String resultToString(Result result)

Writes the result of a transformation to a String. An XML declaration is always omitted.

Parameters:

result - An object (DOMResult or StreamResult) that holds the result of a transformation, which may be XML or plain text.

Returns:

A String representing the content of the result; it may be empty if the content could not be read.
