[xsl] FW: Question about strings.

["Patel, Viral" <viral.patel@xxxxxxxxxxxxxxxxxxxx>]

> Hi,
> 
> I am new to XSL and I have several questions - some of them might be
> really easy ones but I just want to confirm.
> 
> 1. Is it possible to compare two strings lexicographically in XSL/XPATH? I
> believe the answer is no. Is there a way I can achieve this?
> 
> 
> 2. I have listed the XML & XSL below.   In that the community name
> attribute could start with a alphabet, a number or any other character.
> Most of the community names are expected to start with alphabets.  In my
> output, if I have one or more community name starting with a certain
> alphabet (i.e. 'A') then I want to put a link (aka advance orgranizer) at
> the top of the page that would say 'A' and likewise for all the alphabets.
> Also since I have few communities starting with non-alphabets, I would
> want to put a link called Miscellaneous that would link to a page which
> would display all non-alphabetic characters.
> 
> How would I go about doing this?  And the those non-alphabetic characters
> are not fixed, they could vary depending on the XML file used.  If there
> was string comparison allowed then I could do something like @name<'a' or
> @name>'z'  for each node and that would give me all non-alphabetic
> characters.
> 
> Any ideas/help/suggestions would be greatly appreciated.
