testing you XML + DTD

After I've created come simple XML and DTD files, I wanted to test what I've done. Unfortunately, after a little bit of searching over the net , I found out from here that, although Firefox displays and XML's and checks them to be well-formed, it does not support DTD validation of XML files, or any other kind of validation schemas such as XML Schema or Relax NG. So I started looking on the web for some other(free) XML - DTD validator. The first thing found was an online service : validome It is useful for checking XML and DTD files separately, but it doesn't help for validating an XML with the help of an DTD specification. After some more searching, I found two interesting Windows programs: XMLPad and Cooktop. I downloaded and installed the latter, and I found it really helpful. It is very easy to use, and it gets you straight to what you want, and that is checking/validating your files. Not to mention it supports a large variety of formats, such as XML, DTD, XSL, XSD, SVG.
