Please read previous answers once again. You have got answer why you get only one name back and how to deal with it.

From lxml FAQ:

Take a look at the XML specification, it's all about byte sequences and how to map them to text and structure. That leads to rule number one: do not decode your XML data yourself. That's a part of the work of an XML parser, and it does it very well. Just pass it your data as a plain byte stream, it will always do the right thing, by specification.

This also includes not opening XML files in text mode. Make sure you always use binary mode, or, even better, pass the file path into lxml's parse() function to let it do the file opening, reading and closing itself. This is the most simple and most efficient way to do it.
