Re: [Boost-users] is there any lib used to parse XML file in boost?

The best wrapper I have ever used for libxml2/libxslt is a lib called
xmlwrapp (now in sourceforge).  It wraps both libxml and libxslt, provides
sax and tree parsers, and has an iterator style interface.

There are some possibly "hidden" advantages to using a complete library like
xmlwrapp/libxml2 that may not be needed in-the-moment, but downstream can
save huge amounts of time.  First, most xml parsers only read xml, they have
no capability to store and produce xml.  At first blush this doesn't seem
important, but it is fairly easy to produce invalid xml if your just
printf-ing out xml formatted data.  Second, libxml2 integrates with libxslt,
which gives you access to APIs for applying transforms to in memory xml.
This ability (lacking in most libs) can prove invaluable.
