Validating an XML File against a DTD Document Type

This section describes different ways to validate XML files against DTD document types: using standalone XML validation tools, using on-line XML validators, and writing your own XML validation programs.

So far we learned how to use DTD statements to define a document type for an XML file. We also learned how to specify a document type defined by DTD statements to an XML file.

Now let's see how we can validate an XML file against the specified document type. In general, Web browsers like IE and Firefox can be used to browse XML files. But they can not be used to validate XML files. So we have to look for other ways to perform XML DTD validation:

1. Using XML DTD validation tools:

2. Using XML DTD on-line validators:

3. Write your own XML validators with XML DTD validation API:
