Validating xml with xsd in java Free inglaterra cam4
After you have learned more about namespaces, you will see how to use XML Schema to validate complex documents that do use them.Those ideas are discussed in Validating with Multiple Namespaces in Document Object Model.
Activating validation allows the application to tell whether the XML document contains the right tags or whether those tags are in the right sequence.
Remember that your application will not generate a validation exception unless you supply an error handler such as the one here.
As mentioned earlier, warnings are generated only when the SAX parser is processing a DTD.
In other words, it can tell you whether the document is valid.
If validation is not activated, however, it can only tell whether or not the document is well-formed, as was shown in the previous section when you deleted the closing tag from an XML element.
