[jdom-interest] Attribute vs text (fwd)

[Jason Hunter]

Hi Bjorn,

0x0 is a null character.  Somehow that snuck into your file, and it's 
illegal XML.  You could strip null characters wherever they appear in a 
file using a FilterInputStream during the read.  Or you could figure out 
how to keep nulls from getting into XML files.
