XML for Script is a simple, non-validating JavaScript XML parser that is designed to help Web application designers implement cross platform, client-side manipulation of XML data. XML for Script provides both DOM and SAX XML processors as well as a number of other tools that help developers create powerful, Web-based applications. XML for Script seeks to simplify web application development by providing developers the ability to send the data for their application in XML while the presentation is sent in HTML and style sheets. This XML can then be manipulated to initially populate any necessary form elements as well as store changes to the data. When finished with the manipulation of the data, the resulting XML string can then be sent back to the server. Since the data exchange is now 100% XML, the server can then process the new string with its own parser and take the appropriate actions. In effect, XML for Script allows n-tier client side application development to become a reality.

SAX Navigator is a Java Application Programming Interface (API) that sits on top of any Simple API for XML 2.0 (SAX2) implementation to provide "forward-only, pull-model XML navigation".

Arabica is an XML parser toolkit, providing SAX2 and DOM implementations, written in Standard C++.
