QtXml import error

Exml · 04-05-2014, 08:05 PM

Hi,

I'm trying (programming is not my forte

) to adapt the Calibre eBook Editor to my needs, so far I've modified the pretty printing routine, I 've added "support" for Smil files, by that I mean that there is a SMIL folder created in the tree view and those Smil files can be loaded in the editor to be modified.

My problem is the following: I'm trying to import QtXml (from PyQt4.Qt import QtXml) but an error is thrown (ImportError: cannot import name Qtxml) BUT I can see it in the DLLs folder (I'm under Windows).

Could anyone explain to me what is the problem and how to make the Calibre environment aware of the presence of QtXml or any other Python lib/module I have installed on my system for that matter?

I hope you can help me and thank you for this great tool you've created for us it's really helpful

You cannot import QtXml because the PyQt4 QtXml module is not included with calibre. If you want to parse XML dont use QtXml, use lxml, which is much, much better.

And if you want to add your own python modules, just add the import path to sys.path, like you would for any normal python interpreter.
