A Java program to traverse XML document and find nodes using XPath Parser.

Write a Java program that outputs the values of nodes with name x2 and id=“a1” that are direct children of nodes with name x1

<?xml version="1.0" encoding="UTF-8"?>
<root>
	<x1>
		<x2 id="a1">a</x2>
		<x2>b</x2>
		<x2 id="a1">c</x2>
	</x1>
	<x2>d</x2>
	<x2 id="a1">e</x2>
	<x1 id="a1">
		<y1>
			<x2 id="a1">f</x2>
		</y1>
		<x2>g</x2>
		<x2 id="a1">h</x2>
	</x1>
</root>

XPath is an official recommendation of the World Wide Web Consortium (W3C). That's why i am using XPath Parser to find the required nodes in an XML file.

We need to traverse the XML document using XPath Parser and get the nodes with tag x2 with id 'a1' which are direct children of x1.

The program Output form above XML document will be ** x2 = a, x2 = c, x2 = h ** which are direct children of x1.
