XML and the technologies surrounding it have grown immensely in recent years -- in both use and complexity. There's more to know than any one individual can possibly remember. In Essential XML Quick Reference, two leading XML experts present an authoritative reference that covers all the XML-related technologies that matter. In one concise, accessible, example-rich guide, Aaron Skonnard and Martin Gudgin bring together critical information about XML, XSL, XSLT, schemas, namespaces, XPath, SAX, DOM, SOAP, even Microsoft's BizTalk. Following the hugely successful format pioneered by Patrick Chan's Java Almanacs, the authors provide a complete catalog of syntax references, combined with brief, to-the-point overviews of each technology and standard. This ultimate XML reference contains three times the coverage of its nearest competitor. For all developers and Web professionals familiar with the basics of XML.
