Working with XML Created in Different Applications
XML documents can be used to represent almost any kind of information. Unlike
languages such as HTML, XML has no predefined elements. XML is not one format;
rather, XML is used to create specific XML-based markup languages. Just because an
application supports XML does not mean that it can recognize any kind of XML
document. For example, a database application may use an XML format with elements
like <row>, <column>, and <subtotal>, while a graphics application might store
information in elements such as <layer>, <shape>, and <color>. Even though both
documents are XML, they are incompatible because their Document Type Definitions
are completely different.
