The idea behind standards like XML is to have standard tools to work with them, thus eliminating repeating the same mistakes in every implementation. You don't go writing a new regular expression parser every time you need regexes do you? To answer the original email, there are a few XML parsers in common use out there. The main ones for UNIX are probably libxml and expat.I agree with both of the quoted sentiments. I took a look at one of the recommended parsers, and decided that it would take a while to install it and figure out how to use it. However, since: 1) I already have a well tested general token parser; 2) my present XML requirement is close to the most trivial possible; I parsed it directly, with numerous application-specific tests for validity. In a couple of hours, it is tested and running. However, for general application, the use of software conforming standards is certainly preferable. There seems to be a number of choices. How to choose?
Well, I don't know what you evaluated, but late last year I had to through together a C++ XML parser. I remember looking at libxml a long time ago, so this time around I looked at it again.
I found that the current version of libxml2 had a new parsing API that was laughably easy to use directly, or wrap into a C++ class. It was laughably easy for me to wrap it up into a class, and get a robust parser with full namespace support. I could refer to the individual nodes and attributes by uri/name pair directly, without dealing with the headaches of implementing and tracking namespaces.
