<TestSummary>
<product>B2B</product>

I am trying with following code, where i am wrong :

Document doc = parseXmlFile("testReport.xml", false);
Element passelement = (Element)doc.getElementsByTagName("passCount");
Element failelement = (Element)doc.getElementsByTagName("failCount");
Text passtext = (Text)passelement.getFirstChild();
String passstring = passtext.getData();
Text failtext = (Text)failelement.getFirstChild();
String failstring = failtext.getData();

You must be getting a lot of compiler errors. Get a copy of the XML API and chase them down one by one. For example:

Element passelement = (Element)doc.getElementsByTagName("passCount");
Element failelement = (Element)doc.getElementsByTagName("failCount"); 
  

getElementsByTagName() is declared to return a NodeList, not an Element

The tutorial Understanding DOM will also help you to understand the basics of DOM & JAVA...
Using getElementsByTagName is one wise method, try to use them after correcting the errors indicated by William...
Also see this example http://faq.javaranch.com/view?GetElementValueByNameUsingDom for sure!..
