Yes, it is doing exactly what it should, from XML perspective, but not 
enough to get to where you want to go. The XML definition of 'inner' 
text differs from yours. You're looking for all the text content of all 
children of <b> (including <b>?). The xmlNodeListGetString() call 
returns the text content of a given element _only_. The text is usually 
contained inside TEXT children of a given node, hence the inclusion of 
node->xmlChildrenNode as one of the arguments.

In order for you to achieve what you want, you need to go through each 
of the ELEMENT children of <b> and execute xmlNodeListGetString() on 
them (in addition to <b>, if you expect <b> to have text content).

HTH,
Good luck!
