and, just out of curiosity: xml/html parsing

None so far. In fact, it seems unlikely that somebody will come along and implement all the XML stack (DOM, XPath, XML Schema, XSTL, whatever) right now. One chance would be is somebody boostify some existing XML toolkit -- but which one?

Another chance is to initially create "tiny XML" library. In fact, both regression tools and serialization have their own tiny XML parsers and users aksed about XML support for program_options, so such library might really be usefull.

Here is another example of non-validating XML stream parser: http://cttl.sourceforge.net/xml/index.html Igor Kholodov http://cttl.sourceforge.net/
