Method Detail

run

public XdmSequence run(nu.xom.Node context)
                throws XPathException

Return an XdmSequence with the selected nodes. Use runToNodes() if you do not need an XdmSequence.

Parameters:

context - the context node

Returns:

an XdmSequence

Throws:

XPathException - if an error occurred during evaluation.

runToValue

public XS_UntypedAtomic runToValue(nu.xom.Node context)
                            throws XPathException

Evaluates the given expression for the given context node to an xs:untypedAtomic. Use getStringValue() to get the actual value.

Parameters:

context - the context node

Returns:

an XS_UntypedAtomic

Throws:

XPathException - if an error occurred during evaluation.

runToBoolean

public boolean runToBoolean(nu.xom.Node context)
                     throws XPathException

Returns the effective boolean value for the expression and the context node.

Parameters:

context - the context node.

Returns:

the effective boolean value.

Throws:

XPathException - if an error occurred during evaluation.

runToDocuments

public nu.xom.Document[] runToDocuments(nu.xom.Node context)
                                 throws XPathException

Evaluates the expression for the given context node. Results of type element are wrapped into a document.
An Exception is thrown if the expression does not evaluate to an element or a document.

Parameters:

context - the context node

Returns:

a document array.

Throws:

XPathException - if an error occurred during evaluation.

runToNodes

public nu.xom.Node[] runToNodes(nu.xom.Node context)
                         throws XPathException

Returns a Node array with the selected nodes.

Parameters:

context - the context node

Returns:

a node array,

Throws:

XPathException - if an error occurred during evaluation.

getExpression

public java.lang.String getExpression()

Returns the expression represented in this XPath match pattern as string.

Returns:

the expression.
