Java XML – JDOM2 – XPath

Xpath is a query language specification that is used to query an XML path. It provides a language that helps in retrieving specific nodes of an XML document using a query syntax. This tutorial does not explain XPath and assumes that the user is aware of XPath. What we explain here is how to use Xpath to query a JDOM2 document. The default implementation for JDOM2 is jaxen. To run the below examples jaxen needs to be in the classpath. To query the JDOM2 document first compile an XPathExpression using an XPathFactory. Use the expression to then evaluate the JDOM2 document.
