Validating xml against schema in java
DTDs and XSD were normally accessed as configuration options in Simple API for XML (SAX), Document Object Model (DOM), and Java™ API for XML Processing (JAXP). Schematron might use the Transformations API for XML(Tr AX); and still other schema languages required programmers to learn still more APIs, even though they were performing essentially the same operation.Java 5 introduced the package to provide a schema-language-independent interface to validation services.This is useful for adding constraints that are more easily checked in a Turing-complete language like Java than in a declarative language like the W3C XML Schema language.You can define a mini-schema language, write a quick implementation, and plug it into the validation layer.This package is also available in Java 1.3 and later when you install JAXP 1.3 separately.Among other products, an implementation of this library is included with Xerces 2.8. If you validate in multiple threads simultaneously, make sure each one has its own However, normally this isn't what you want.
Depending of you enterprise security policy, some - if not most of your middleware servers have no access to Internet.
Typically, the URL is the namespace Uniform Resource Identifier (URI) for the schema language. However, you can install additional libraries that add support for these and other schema languages.
The Java programming language isn't limited to a single schema factory.
It’s even worse when your development infrastructure is isolated from the Internet (such as banks or security companies).
In this case, validating your XML against schemas becomes a real nightmare.
However, once you learn the API for validating DOM documents against RELAX NG schemas (for instance), you can use the same API to validate JDOM documents against W3C schemas. Schema Instance(Schema Factory.java:186) at Docbook RELAXNGCheck.main(Docbook RELAXNGCheck.java:14) This isn't a closed list.
