Validating xml with dtd in java Sites for dirty chatting with man without registration
By parsing an XML document according to the rules specified in a DTD or an XML schema, a validating XML parser determines whether the document conforms to the specified DTD or XML schema.If the XML document does conform, then the document is valid, which means that the structure of the document conforms to the DTD or schema rules.You can access the JAXP specification, which is produced by Sun Microsystems, at the following URL: DOM Stream access to XML nodes is done by PL/SQL and Java APIs.
DOM provides classes and methods to navigate and process the tree.Thus JPEG, Word, PDF, RTF, and HTML documents can be more readily stored.DOM builds an in-memory tree representation of the XML document.Only some of the Oracle-specific features are available through the extension mechanism provided in JAXP.
If an application uses these extensions, however, then the flexibility of switching implementation is lost.
In general, the advantage of JAXP is that you can use it to write interoperable applications.
