The following figure shows the appearance of opening an XML document on a web browser. You can click on the " " and "-" sign to expand and collapse a portion of the tree., if its structure meets the XML specification, i.e., it is syntactically correct.
The SAX interface is modular, and in SAX 2 includes several classes specifically designed for tracking SAX events.
These include the following interfaces and methods, according to the SAX Project API documents.
(This is not an exhaustive list, but an overview of some of the more useful and DTD-specific methods.) Now, to write the code, you need an editor.
Stylus Studio® includes a built-in Java Editor and Debugger and powerful Java code generation facilities.
You can also add, as a Custom Validation Engine, the Sun Multi Schema Validator which will parse DTDs as part of its validation steps.
It can also be invoked implicitly as part of the XML parsing process when running the various Java-based XSLT engines, such as Saxon and Xalan-J.Take it out for a free test drive, and parse those DTDs! With Stylus Studio® X16 XML Enterprise Suite, you get the most comprehensive XML tool suite at one incredibly low price.Value: it's just one of many reasons why smart XML developers are choosing Stylus Studio!As for DTD validation to find little on the Internet, I would like to explain briefly how this is possible by simply using Java resources. An external component has delivered a XHTML file, which should have been “xhtml1-strict” according to the W3C schema definition. But unfortunately, this file was incorrectly because no schema validation check took place during/after the generation. A subsequent XML comparator (Delta XML) should compare this file with default settings and chrased, because the delivered XHTML was invalid. A validator class package it.heber.sandbox; import parsers.
