detecting a colon (':') within a para

Is there anyway to find the following scenario:

<para>The following items you really need to
know:</para>

I'd like to be able to find all para's that have a
colon as their last character and insert a processing
instruction to tell the output-formatter not to allow
a page break.  I use processing instructions in many
other scenarios, but I've never had to look an
elements actual content.  Any suggestions would be
appreciated.

Thanks!

Naomi
