It is right - it is how the DOM works (I mean the W3C DOM in general, not
just the Python one you are using). The character data is contained in one
or more text nodes that are children of the containing element node. If it
happens that your data ends up all in one node , that text node will be the
first child node of the element node. That is just what you report getting.
Be aware that it is possible to have the character data split up among
several text nodes, and you would then have to collect them all. This
should not happen in your case if all the files look like your sample.
