Parse xml form

Hi,

I need to parse a KM folder that contains xml files created by XML Forms Builder. I need to get to a specific node in the xml. For example if i have the nodes: "Subject "Date" "Title" ... i need to show only the "Subject" node.

I succeed in getting the InputStream by using the code -

resource.getUnfilteredContent().getInputStream()

But i don't know how to proceed.

Thanks in advance,

Keren
