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?

The W3C offers one. There are also online converters.

The 'online converters' XML Utilities link is currently out-of-date.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 :-) ). – Columnist 4/12, 2013 at 11:10

lumrix.net tool also gone – Nainsook 31/12, 2014 at 10:19

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_tools – Thiel 22/8, 2016 at 19:37

The lumrix.net link is also broken/out-of-date.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... – Griseldagriseldis 28/9, 2016 at 12:6

Does JDK have command line tool from DTD to XSD conversion? – Mandelbaum 25/1, 2017 at 16:46

The lumrix dtd2xs tool (Java) can be found here: github.com/reposit/dtd2xs This worked for me: java -cp . dtd2xsd report.dtd > report.xsd – Anaemic 2/2, 2017 at 14:0

W3C tool requires Perl installation – Cockerel 30/10, 2017 at 13:8

the w3c one is actually broken, I guess it is too old. it generates invalid xsd. – Ultimate 16/5, 2021 at 9:36

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.

Nice, worked perfectly in VS2012. The option is found in the main menu under XML -> Create schema – Malacostracan 4/1, 2014 at 14:32

Seems supported by the 2015 community edition as well. :) Thanks! – Entoderm 26/2, 2016 at 14:17

Visual Studio Community 2015 >>> open .dtd file >>> XML tab >>> Create Schema – Harve 18/4, 2017 at 15:34

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

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! – Hague 26/3, 2012 at 8:48

can't parse the w3c strict.dtd file. – Meshuga 12/1, 2013 at 16:21
