Among other things, for example, the chances are small that the schema will be stored under the same name on different computers.By definition, an application validates a document if there's a risk that the document is incorrect.

On the other hand, an XML is considered valid if it follows the rules specified in the DTD or XSD.

This tip discusses new features in Java API for XML Processing (JAXP) 1.2 that give you more flexibility in validating documents against schemas.

Typically, an application validates XML documents against a list of known schemas as part of its error handling.

However, the disadvantage is that DOM parses and stores the entire document, even if you only care about part of it.

Section 23.3 (Parsing XML Documents with SAX 2.0) discusses an alternative approach appropriate for cases when you are dealing with very large XML documents but care about only small sections of them.

In essence, XML has done for data what the Java language has done for programs: This chapter doesn't focus on how to write XML but rather how to process XML documents with Java.

We show you how to use Java to process XML documents by using the Document Object Model (DOM), the Simple API for XML (SAX), and the Extensible Style sheet Language for Transformations (XSLT).

The first property (To test Listing 2, you need a JAXP 1.2-compliant parser.

Check the documentation for your favorite parser or download the most recent version of Apache Xerces (I have used version 2.4.0 to prepare this tip).

The validation cannot be robust if it depends on the content of the document, such as JAXP uses URIs as identifiers for properties and attributes, which is consistent with the use of URIs as namespace identifiers.
