getXPath

protected org.jaxen.XPath getXPath(org.w3c.dom.Node contextNode,
                                   java.lang.String expression)

public org.w3c.dom.NodeList selectNodeList(org.w3c.dom.Node contextNode,
                                           java.lang.String expression)
                                    throws JRException

Description copied from interface: JRXPathExecuter

Selects a node list by evaluating an XPath expression on a context node.

Specified by:

selectNodeList in interface JRXPathExecuter

Overrides:

selectNodeList in class JaxenXPathExecuter

Parameters:

contextNode - the context node (a document can also be used)

expression - the XPath expression

Returns:

the selected node list

Throws:

JRException - if the XPath evaluation failed

selectObject

public java.lang.Object selectObject(org.w3c.dom.Node contextNode,
                                     java.lang.String expression)
                              throws JRException

Description copied from interface: JRXPathExecuter

Selects an object by evaluating an XPath expression on a context node.

If the expression evaluates to a node list, the first node in the list should be returned. Otherwise, the primitive value resulted from the evaluation should be returned as a java.lang.String, java.lang.Number or java.lang.Boolean.

Specified by:

selectObject in interface JRXPathExecuter

Overrides:

selectObject in class JaxenXPathExecuter

Parameters:

contextNode - the context node (a document can also be used)

expression - the XPath expression

Returns:

the selected node or value

Throws:

JRException - if the XPath evaluation failed

containsPrefixes

protected boolean containsPrefixes(java.lang.String expression)

addNamespaceContext

protected void addNamespaceContext(org.w3c.dom.Node contextNode,
                                   org.jaxen.XPath xPath,
                                   java.lang.String expression)
                            throws JRException

Throws:
