Re: [Discuss-gnuradio] attribute error DTD

[Josh Blum]

There is a problem with the installed version of python-lxml package. My 
machine has lxml version 2.1.1. The latest version of lxml is 2.1.5 
(http://codespeak.net/lxml/index.html#download).

Perhaps you have a very old version of lxml that is missing some feature 
(in this case DTD). Install the latest lxml from the website, or see if 
your package manager has an update available.

For the record, what version of lxml do you have? Either check your 
package manager (yast2?) or run this commmand:
python -c "from lxml import etree;print etree.LXML_VERSION"
