The SAX interface of the xml4c2 parser
I've taken a look at the SAX interface of the IBM xml4c2 parser http://www.alphaworks.ibm.com/tech/xml4c In short, I don't like it. I don't like returning "const XMLCh*" instead of "const wstring&" or "const string&" (even though an approach like this would be more efficient for an expat wrapper). I don't need the index out of range warning capability, because I iterate through the AttributeList entries anyway. I don't like giving an AttributeList& argument to DocumentHandler::startElement(), instead of an AttributeList*, because this rules out the possibility of passing a null-pointer on for the cases that don't have an attribute list. Hm... so far there is AFAIK 4 incompatible C++ SAX implementations around. The IBM one, and: http://www.jezuk.demon.co.uk/SAX/ http://www.cgocable.net/~mlepage/minion/doc/ http://www.vivid-creations.com/free/sax.h I also have an expat-wrapper-based C++ SAX implementation, similar to Jez Higgins' one (I use a "sax_" prefix instead of namespaces, since it has to run on compilers without namespace support). No time to create a web page for it yet. My reasons for going SAX, was: 1. it seemed silly to invent my own abstraction when lots of work had already gone into the SAX design 2. make it possible to drop-in replace the parser But #2 can only be achieved if the different SAX implementations have the same API, and this is not currently the case. I'll go whatever way the majority goes, unless it leads towards the IBM implementation. xml-dev: A list for W3C XML Developers. To post, mailto:xml-dev@i...
