Free DTD to XSD conversion utility?

Question

I have a DTD that I need to convert to an XSD (XML schema) file. Is there a free utility or simple way to accomplish this?

Answer 1

The W3C offers one. There are also online converters.

Answer 2

I've used http://www.hitsw.com/xml_utilites/ once or twice and it works well. You can also try to use one provided by the wc3.

Trang converts between different schema languages for XML. It supports the following languages:

• RELAX NG (XML syntax)
• RELAX NG compact syntax
• XML 1.0 DTDs
• W3C XML Schema
