I know of at least three light weight C++ XML parsers: RapidXML, TinyXML and PugiXML. However, all three use a DOM based interface (ie, they build their own in-memory representation of the XML document and then provide an interface to traverse and manipulate it). For most situations that I have to deal with, I much prefer the SAX interface (where the parser just spits out a stream of events like start-of-tag, and the application code is responsible for doing whatever it wants based on those events).
Can anyone recommend a light weight C++ XML library with a SAX interface?
Edit: I should also note the Microsoft XmlLite library, which does use a SAX interface (well, actually a "pull" interface which is possibly even better). Unfortunately, it's ruled out for me at the moment since as far as I know it's closed source and Windows only (please correct me if I'm wrong on this).
I've used expat when I needed to parse XML. It's very light-weight (well, it used to be; it's a while since I've done XML stuff) and does the job.
you can try http://die-xml.googlecode.com/ . it seems to be very small and easy to use
this is a recently made C++0x XML SAX parser open source and the author is willing feedbacks
it parses an input stream and generates events on callbacks compatible to std::function
the stack machine uses finite automata as a backend and some events (start tag and text nodes) use iterators in order to minimize buffering, making it pretty lightweight
PugiXML and RapidXML do not have DOM conforming interfaces.. those API came with severe limitations on functionalities and conformance. You might want to investigate VTD-XML that is signifiantly more advanced than either DOM or SAX/Pull
