It seems as if everywhere you look there is some new XML-related tool being released in source code form written in Java.Despite Java's apparent dominance in the XML arena, many C/C programmers do XML development, and there are a large assortment of XML tools for the C and C programmer.
It differs in basic concept from other schema languages in that it not based on grammars but on finding tree patterns in the parsed document.
If I take this incremental document and export it to XML with its to String() method, create a new document from it with XML:: Lib XML-validate(), it *always* behaves as expected.
If I pass it the XML:: Lib XML:: Document object I've been frobbing, it sometimes says the invalid XML is, in fact, valid.
This ubiquity made web-based applications possible. By having a common, albeit limited language from which to build user interfaces, client-server applications could often abandon the use of platform- and application-specific client-side executables in favor of accessing data and logic on the server through the CGI or Web server extension.
The importance of HTML's ubiquity in web applications is especially noticeable in the class of applications I'll call "in-browser content editors".
This approach allows many kinds of structures to be represented which are inconvenient and difficult in grammar-based schema languages.

At the time of this writing, XML:: Lib XML could only validate with DOM parsing—validation is not available with SAX-style parsing.
