public bool parse_file
Fills the GstXML object with the corresponding elements from the XML file fname.
Optionally it will only build the element from the element node root (if it is not NULL). This feature is useful if you only want to build a
specific element from an XML file but not the pipeline it is embedded in.
Pass "-" as fname to read from stdin. You can also pass a URI of any format that libxml supports, including http.
||The filename with the xml description
||The name of the root object to build
|TRUE on success, FALSE otherwise
