public void setXmlNamespaceMap(Map<String,String> xmlNamespaceMap)
                        throws JRException

Throws:

JRException

getDetectXmlNamespaces

public boolean getDetectXmlNamespaces()

setDetectXmlNamespaces

public void setDetectXmlNamespaces(boolean detectXmlNamespaces)

getXPath

protected org.jaxen.XPath getXPath(Node contextNode,
                       String expression)
                            throws JRException

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:
