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?

Solution 1

The W3C offers one. There are also online converters.

Solution 2

If you happen to have Visual Studio, open the DTD file an you should have a button to "Create Schema" out of it.
I haven't checked if it was available on Express edition, though.

Solution 3

Try xmlpad from https://download.cnet.com/XmlPad/3000-7241_4-10252051.html to convert DTD to XSD. Really nice tool.

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

You need to open a DTD file before you can access the requested functionality (convert DTD to XSD in this case; it can also generate a sample XML). Works great, thanks!

can't parse the w3c strict.dtd file.

The 'online converters' XML Utilities link is currently out-of-date. The tool moved to: http://www.xmlutilities.net. But now you'll have to request for access. I found a link to this tool http://www.lumrix.net/dtd2xs.php in an O'REILLY article and it worked well for me (you do need the Java Runtime Environment installed, but most of us still have that :-) ).

Nice, worked perfectly in VS2012. The option is found in the main menu under XML -> Create schema

Site down. Cannot reach.

lumrix.net tool also gone

Seems supported by the 2015 community edition as well. :) Thanks!

Good things disappear quickly from the internet.

There is another version of the W3C tool here mathling.com/xmlschema . Found it here: edutechwiki.unige.ch/en/XML_Schema#DTD_to_XSD_Conversion_too‌​ls

The lumrix.net link is also broken/out-of-date. A Google search on just "dtd2xs.php" turns up quite a few hits, but most are the same link, or sites that I was a little nervous about downloading from...

Does JDK have command line tool from DTD to XSD conversion?

The lumrix dtd2xs tool (Java) can be found here: github.com/reposit/dtd2xs This worked for me: java -cp . dtd2xsd report.dtd > report.xsd

Visual Studio Community 2015 >>> open .dtd file >>> XML tab >>> Create Schema

W3C tool requires Perl installation

The website is down.

The thaiopensource link currently redirects to relaxng.org/jclark/trang-manual.html

the w3c one is actually broken, I guess it is too old. it generates invalid xsd.

Currently, that URL comes up with my firewall flagging it as malware.
