(An incorrect schema won't help when you try to use it later to validate your XML data.) Nowadays, most programmers' text editors -- particularly the ones found in IDEs -- have decent macro and template support for features like syntax highlighting and autocompletion of a partially typed word or phrase.
Therefore I am omitting from this discussion any XML editors that do only syntax highlighting and autocompletion.
Also, I'll leave the more detailed explanations of XML to the background sources in Related topics.
All of the other tools have noncommercial licenses that require no fee for use, but if you're using them in commercial projects, make sure that your intended use complies with the terms of the license.
The second set of tools includes software libraries that will add parsing and XML-generation features to your application.
An XML dialect is just a particular set of XML tags along with some rules for how the tags fit together.
Finally, we'll conclude with a list and discussion of libraries either usable from or actually written in C and/or C .
In this article, I'll skip arguments for using XML; I'll assume that you already have good reasons for wanting to ramp up on this technology.
The most common open-source licenses are Apache, GPL, BSD, and LGPL.
