Not sure what you are asking, but I'll take a stab in the dark.
When you retrieve geometry as SVG what you get back is the contents of a
path attribute node.
So if an SVG path element is written <path d="X"/> the result of the query
is "X", or the value of the 'd' (data) attribute, not an XML element, and
certainly not a valid SVG document. You have to construct these yourself.
