Hi,

The <error> tag is documented at http://www.mediawiki.org/wiki/API:Errors I am looking the same kind of documentation for the <warnings> tag. Is there documentation about it ?

No, but there should be.

I have modified my tool to log messages in case of errors reported by the API, and I would like to do the same for warnings, but I'd like to be sure about the format.

For example, I received the following warning :

<api> <warnings> <ApiPageSet> Too many values supplied for parameter 'titles': the limit is 50 </ApiPageSet> </warnings> ...

Is it always the same format : a code in a tag, and the description as text ?

Yes. The code in the tag is the name of the module that threw the warning (so your example is a bug: the tag should be <query>), and the warnings themselves are inside the tag, separated by newlines.
