Microsoft Corp. announced the newest version of its MSXML parser with built-in support for version 2.0 of the Simple API for XML (SAX2). The decision to implement the SAX2 programming interface, rather than develop a new one, is a reflection of Microsoft’s commitment to deliver the features its customers demand. SAX2 is designed to enable faster and more efficient processing of XML by allowing programs to read, review and process XML files without having to load the entire document into memory. The latest version of the MSXML parser, the third in a series of XML parser technology previews Microsoft began releasing in January 2000, provides another programming interface for building Web-based distributed applications based on standard XML messages. These releases allow Microsoft to achieve its goal of providing new features and updated support for standards in “Web time.” In addition to the new SAX2 support, this release also adds more support for XSLT and Xpath. Development of SAX began in December 1997; its first release was in May 1998. SAX was a collaborative effort developed entirely by the members of the XML-DEV mailing list. The SAX interface is free for commercial and noncommercial use. Although the list of contributors credits over 80 people, including some of the original developers of XML, David Megginson of Megginson Technologies Ltd. ( is considered to be the primary developer and maintainer of SAX. SAX 2.0 was released on May 5, 2000. The new release is available for immediate download at
