Given the amount of time I spend explaining 'simple' Namespace, XPath, XSD, DTD, etc.. issues to people, I would fall heavily on the 'not easy' side of the issue. It is 'easy' if you take the time to sit down and study it and think about it. The problem is that XML's design suffers some serious impedance mismatches with your average app developer, at least in my experience. The problem is not so much that things are complicated, but that things are not what is expected by a large percentage of people trying to _use_ it. Most of the people who sit down design/code applications which use XML are not members of XML-Dev. They do not have easy access to experienced XML heads. The pick up and use just-enough to get the job done. Part of my job ends up being to convince people that XML really is complex enough to mandate using existing tools, rather than rolling-your-own. XML is simple enough to fool people into thinking that they can get away with customized code, but in the open world of the internet, this is dangerous. A public webservice should only accept _well_formed_ XML, not just something which looks like XML, otherwise you end up with customers depending on the ability to accept non-well-formed XML. Convincing your average developer that standards conformance is like pulling teeth. Developers are taught to cut corners for performance, so arguing that such 'obvious' spots for improvement as XML parsing, need the extra work to be conformant (especially when you are Microsoft, the Evil Empire <g>), is not an easy sell. XML-Dev is a wonderful little world, but the people here are hardly representative of the average XML user, in many, many ways. -derek The views expressed above are my own and are not necessarily those of my employer.
