The question does not have to be directly related to Linux and any language is fair game.

This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

when using a DTD i believe you can have an element required.
could this be solved with an if/else-like statement? you can use <xsl:when>... elements to test whether the data was given or not.
what you are trying to do is to require that the element contains data (not just attributes)
<product id="34" />
doesnt supply CDATA.. only the attributes
gives data to the element, along with an attribute.
(dunno where i was going with this, sorry lol)
i think maybe using a DTD making the element of type DATA and #REQUIRED.
no actually, I am trying to process in perl.
I have > 600 big XML files. > 7 million lines.
Using saxon Xquery it is is veryslow even to
extract a simple query. Plus it uses about
20MegaGigaBugga bytes for each file.
So i am trying a perl method, which is much quicker.
And it would just be easier if all tags were closed off properly.
