XML PARSER in Secondlife Client

We need a XML parser to improve communication with internet (RSS, ATOM, ebxml, ..), to stock values in a hierarchical XML object. This parser must integrate xpath to serach and retrieve informations from the xml object.

Functions are like the xmlSDK from microsoft:
- xmlobject.selectSingleNode("xpath expression"
- xmlobject.selectNodes("xpath expression"
- node.getAttribut
- node.setAttribut
- node.text
