ABSTRACT
An XML document consists of A typical XML document is show below. DTDs are added to XML documents, which ought to be accessible to other developers, to allow parsers other than the Flash player to parse the documents. Recently there has arisen a new type of XML document, which looks like XML but has some modifications compared to a regular XML document. Namespaces in XML documents allow similar documents with the same node or element name but different meanings to be distinguished. The information for RSS feeds and Web services is also stored in XML documents, because it is all database-type information. Some errors may not affect the parsing of an XML document by Flash, but it is safer and a good habit to correct any errors before proceeding further. XPath has more than 100 built-in functions allowing navigation within XML documents. Basically an XHTML page is an XML document containing HTML.
