RE: [xsl] Filtering out books with short description

["Karl Koch" <TheRanger@xxxxxxx>]

Hello,

and thank you for the script. Is seems to work. I have one question
regarding this script. In the line:

<xsl:apply-templates select="book[string-length(description) &gt;
> 5]" /> 

Is it ensured that (description) only considers "description" being a direct
child of "book". What would happen if there would (sometimes) be another
"description" tag deeper inside the structure. Would this script than also
pick on that one? If yes, how could this be avoided. I checked in my output
(please remember, my orginal datastructure is much more complicated) and it
seems only to consider /book/description but I can't really explain why that
should be...

The second question is: What does "&gt" mean?

Karl
