Is there a function which do this work?
Don't know the C API, but in XSLT there's the function normalize-space()
and it does just what you want, so you might want to take a look at the
source of LibXSLT. Or use XSLT directly.
I spent a bit of time looking for the C call today and wasn't able to
find it. In fact, I doubt there is one, since all space is treated by
libxml2 as significant (see  and ).
<xsl:template match="text()" priority="2">
The XSLT solution suggested is the best way in lieu of actually
normalizing the space in C - the choice is yours.
As a side-note, I thought one could get, at least partially, to
eliminating extra white-space using the XML_PARSE_NOBLANKS (as suggested
by Daniel in ), but the functionality behind the option seems to have
been modified. I recall being able to remove empty nodes (<node/>) from
the document being parsed using that option -- that is no longer the case.
All the best,
