Yes. It's actually required by DOM standard: NodeList (which is returned 
from getElementsByTagName) should return 'null' (None in Python) on 
unknown index:

Like this for example:
<filename><child/><child/></filename>

or like this:

<filename>I'm a text child node <ElementChildNode/></filename>

It's not related to children. There are several types of nodes: 
documents, elements, text, comments, processing instructions (things in 
<??>)... Their nodeValue depends on their nature.

Almost :-). Here filename has actually 5 nodes:
1. text node '\n  '
2. element node 'child'
3. text node '\n  '
4. element node 'child'
5. text node '\n'

In other words: in DOM whitespace counts.
