How to read XML using XPath in Java
- by kaibuki
Hi guys,
I want to read XML data using XPath in Java, so for the information I have gathered I am not able to parse XML according to my requirement.
here is what I want to do:
Get XML file from online via its URL, then use XPath to parse it, I want to create two methods in it. One is in which I enter a specific node attribute id, and I get all the child nodes as result, and second is suppose I just want to get a specific child node value only

In above example I want to read all the elements if I search via @name and also one function in which I just want the url from @name 'Javascript' only return one node element.
I hope I cleared my question :)
Thanks.
