Generate XPath for html elements

I am working on project in java where I need to get the xpath for available elements on HTML page, do you have any idea about it or if you can suggest something… what I need is as we have text field or label on page, I want or generate the xpath for both the element available on page. I will get the html source code, now I have to process it to generate the xpath only for available element on page.

I would appreciate your inputs.
