Open-source XML Editors for Content Management Systems
Directory of Proprietary XML Editors
A wide variety of XML editors are available for use by CMS developers. Most are desktop authoring tools like Altova XMLSpy and Justsystems XMetaL. But some specialize in "through-the-web" editing in a browser. Many of the desktop tools now offer some browser support, often with a plug-in for a single browser. Many try to deliver WYSIWYG ("what-you-see-is-what-you-get") editing.
