How to parse xmlwebservice in phonegap

I am new in phonegap development. I am making one platform independent mobile application by use of HTML5,CSS . I want to call xml based webservice in my phonegap application and 开发者_开发百科wants to parse that service. Please, any body suggest me how is it possible with simple example.

As mentioned in this answer:

How call SOAP based web-Service using PhoneGap in iPhone?

"calling a webservice with phonegap is the same than calling it directly from your browser" (except he is incorrect about the same domain policy as PhoneGap apps are loaded via file:// reference and are thus exempt).

Perhaps the link in his answer could help?
