Android XPath is available (i.e. as a ready-to-use implementation) since Android API Level 8 (I think thats Android 2.2) you can find more information here.

To get you started - within the scope of an activity try:

XPath xpath = XPathFactory.newInstance().newXPath();
String expression = "myNode";
NodeList nodes = (NodeList) xpath.evaluate(expression, parser, XPathConstants.NODESET);

The "parser" can be obtained by putting ur xml document into your res/xml folder (you might have to create that xml folder yourself). Then you can access it via:

//Do this withon the scope of an activity, you need the activitie's context!
Resources res = getResources();
//Get the xml file
//this is how you access the content of the xml folder 
//you previously created in the res folder
parser = res.getXml(R.xml.yourxmlfile);
