                        throws JRException

Throws:

JRException

getDetectXmlNamespaces

JRException

selectNodeList

public NodeList selectNodeList(Node contextNode,
                      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 Object selectObject(Node contextNode,
                  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(String expression)

addNamespaceContext

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

Throws:
