DTD comparison
As a follow-up on my toying with DTDs, I added a new Python script to my toolbox this morning: dtd-compare.py allows to compare the vocabularies defined in several DTDs to see which elements and attributes are present or absent among them.
For instance, running python dtd-compare.py http://www.w3.org/TR/xhtml-basic/xhtml-basic10.dtd http://www.openmobilealliance.org/tech/DTD/xhtml-mobile10.dtd http://www.w3.org/TR/xhtml-basic/xhtml-basic11.dtd http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd has allowed me to build a comparison of the various mobile XHTML flavors with the content of XHTML 1.0 Strict.
I haven’t included XHTML MP 1.1 and XHTML MP 1.2 in that comparison chart since the officlal DTDs seems to have syntax errors, reported by the script as follows:
ERROR: character set conversion problem: 'utf8' codec can't decode byte 0xa9 in position 260: unexpected code byte at http://www.openmobilealliance.org/tech/DTD/xhtml-mobile11.dtd:1:0 ERROR: character set conversion problem: 'utf8' codec can't decode byte 0x92 in position 715: unexpected code byte at http://www.openmobilealliance.org/tech/DTD/xhtmlmp12-form-1.mod:1:0

Comparisons of XHTML flavors…
As a follow-up on my XHTML Basic 1.1 cheat sheet, I’ve continued to play with the parsing of DTDs to make it possible to generate automatically comparisons of what the various flavors of XHTML contain in terms of elements and attributes.
The comparis…

The error on the XHTML MP 1.1 DTD was already described by Ruadhan, over at dev.mobi.
I’m sending a bug reports on both issues to the OMA technical questions mailing list, will see how that goes.

I just added MP 1.1 and 1.2 to the table, using local corrected copies of the DTD.
I would like to find a better way to display the data in this big table, though…
