I created DTD file for repomd.xml. It is available at:
http://miroslav.suchy.cz/spacewalk/repomd.dtd
Using this file you can validate whether you repomd.xml file is valid.
There is two way (at least) how to validate repomd.xml.
a) since repomd.xml do not have DOCTYPE element you can insert it there:
e.g.:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE repomd PUBLIC "-//Red Hat//repomd.xml DTD 1.0//EN"
"http://miroslav.suchy.cz/spacewalk/repomd.dtd";>
<repomd>
...
And then run:
xmllint --loaddtd --noout --valid /tmp/repomd.xml
This way you did not get any error (assuming you repomd.xml file is valid)
b) run:
$ wget http://miroslav.suchy.cz/spacewalk/repomd.dtd
$ xmllint --noout --valid --dtdvalid file:///home/msuchy/repomd.dtd
/tmp/repomd.xml
But this way you get one error, which is safe to ignore (for now):
/tmp/repomd.xml:2: validity error : Validation failed: no DTD found !
<repomd>
^
I created this DTD according to my study of RHEL5 and F12 repomd.xml
file and quick study of yum code source. If you think I missed some
allowed element or attribute or if you see some error in DTD (it is my
first) feel free to comment it.
I would like to start discussion if FPI I suggested is appropriate. And
even find better home url for this document other then my homepage.
If you find this usefull I can continue with creating DTD for other
xmlfiles like filelists.xml and primary.xml.
Comments?
