Ok, so what are you doing to serialise this result? Are you using the "format"
option? That will not always give you the expected result, as libxml2 cannot
easily distinguish between "ignorable" and meaningful whitespace.

Two options:

- parse with the XML_PARSE_NOBLANKS option to remove whitespace

- copy the whitespace text nodes when you copy the element nodes
