This is because typically the first child of the document is
not the root element of the document it's text XML processing
instructions etc...

Because the first child of the Root element is most likely
the whitespace from the end of the opening 'g' tag to
the start of the tag for the first element. You need to
filter the children based on the Node Type, to avoid the
Text nodes you don't care about (the TextNodes are important
for things like, well 'text').

The Whitespace consists of a single 'newline' in this case.
