Why do you need the original XML? The Layer .features[0] has the
linestring, and you can iterate over .geometry.components to get them out...

It's unclear to me what you're having problems accessing. The Geometry
is a 


which is a subclass of 


and has points as .components, which you can .clone() to make your own
features, or access .x, .y of.
