[docs] xml.dom.pulldom strange behavior

[Vojtěch Rylko]

  Hi,

I have file with 10 000 records of same element item (always same):

$ head test.xml
<channel>
<item><section>Twitter</section></item>
<item><section>Twitter</section></item>
<item><section>Twitter</section></item>
<item><section>Twitter</section></item>
<item><section>Twitter</section></item>
<item><section>Twitter</section></item>
<item><section>Twitter</section></item>
<item><section>Twitter</section></item>
<item><section>Twitter</section></item>

And run simply program for printing content of element section:

$ python pulldom.py test.xml | head
Twitter
Twitter
Twitter
Twitter
Twitter
Twitter
Twitter
Twitter
Twitter
Twitter

Seems work fine:
$ python pulldom.py test.xml | wc -l
10000

But (in two cases of 10 000) gives me just "Twi" not Twitter:
$ python pulldom.py test.xml  | grep -v Twitter
Twi
Twi


Why? This example program demonstrate big problems in my real 
application - xml.dom.pulldom is cutting content of some elements.

Thanks for any advice
