Subject: REXML - Empty string error

Hi all,

I am parsing some XML with XPATH and REXML. A snippet is below:

..
e.elements['Questions'].text << "," <<
e.elements['Offers'].text << "," <<
e.elements['ID'].text << "," <<
..

The ID XML tag is often an empty tag (no data in it) and this throws an
error in my script of

.rb:364:in `<<': can't convert nil into String (TypeError)

How do I ignore this error? I just want to take whatever is in the XML
(even if it is empty) and carry on to the next data set.

Many thanks
