JDomXmlObject(org.jdom.Document document, Map<String,String> namespaces)

JDomXmlObject(org.jdom.Element element)
Constructs a new xml object based on a JDMO Element.

JDomXmlObject(org.jdom.Element element, Map<String,String> namespaces)

Method Summary

Specified by:

compile in interface XmlObject

Parameters:

path - The xpath expression

Returns:

The compiled xpath expression

Throws:

org.jdom.JDOMException

getElement

public org.jdom.Element getElement()

Returns the JDMO Element.

getAttribute

public org.jdom.Attribute getAttribute()

Returns the JDMO Attribute.
