Tutorial: Parsing an XML Document with XPath

The getter methods in the org.w3c.dom package API are commonly used to parse an XML document. But J2SE 5.0 also provides the javax.xml.xpath package to parse an XML document with the XML Path Language (XPath) .

Tutorial Details:

The JDOM org.jdom.xpath.XPath class also has methods to select XML document node(s) with an XPath expression, which consists of a location path of an XML document node or a list of nodes.

Parsing an XML document with an XPath expression is more efficient than the getter methods, because with XPath expressions, an Element node may be selected without iterating over a node list. Node lists retrieved with the getter methods have to be iterated over to retrieve the value of element nodes. For example, the second article node in the journal node in the example XML document in this tutorial (listed in the Overview section below) may be retrieved with the XPath expression:
