Hi all,
I have been trying to get this working for hours and days now and need a fresh
pair of eyes to tell me what I'm doing wrong. I hope someone out there can
help. Thanks you so much in advance if you able to help :)
BACKGROUND INFO
I have the following two xml files that are combined together into one xml file
and then transformed using server side XSLT, PHP and the MODx content
management system.
WHAT I AM TRYING TO DO
From a long list of hotels in the xml file (hotellist.xml - please see below),
I am trying to call ONE hotel in particular with the ID of '1234567' and get
it's 'hotelurl' value and place this into a link using XSLT.
THE PROBLEM
The problem I am having with the XSL below is with the 'ThisHotelID' variable
and 'HotelURL' variable. I don't get an error but I can't seem to be able to
get the value of the 'ThisHotelID' variable into the variable of 'HotelURL' -
it seems to just ignore it and parse the variable as if it's empty?!
MY QUESTIONS
What am I doing wrong here?
Are you not able to put a variable within another variable?
What is the best way to do this?

Consider to use
<xsl:variable name="ThisHotelID"
select="document(file[1]/@href)/Hotel/HotelID"/>
<xsl:variable name="HotelURL"
select="document(file[2]/@href)/hotels/hotel[(_at_)id =$ThisHotelID]/hotelurl"/>

Hi Martin Honnen,
Unfortunately I have tried that and it still does not work - it's so
frustrating, it's probably something simple but I just can't see it. Any other
ideas?
Many thanks,
Alan
