Concurrent DTD & XSD validation in XML

Is it possible to validate XML document by DTD and XSD at the same time?

What I mean is, can the DTD & XSD validation code be inserted in the XML file?

Here is my code:

ns.xml

<?xml version="1.0" encoding="UTF-8" ?>
   
           //DTD//
<!DOCTYPE root SYSTEM "ns.dtd">

          //XSD//
<ss:root xmlns:ss="http://example.com/ns"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://example.com/ns ns.xsd">
</ss:root>
Solution

  • Is it possible to validate XML document by DTD & XSD at the same time?

    Yes, of course an XML file can be validated against any number of schemas – DTDs, XSDs, Schematron, RELAX NG, etc.

    Unlike with DTDs, there is no standard way in which to embed XSDs within an XML file.
