RE: concat variable names


Hi Michael:

Variable names are constant, so you can't create them dynamically in the
way you describe.  I would recommend something like this:

<xsl:variable name="mySettings.tf">
   <Setting Name="var_1">value_of_var1</Setting>
   <Setting Name="var_2">value_of_var2</Setting>   
   <Setting Name="var_3">value_of_var3</Setting>
   <Setting Name="var_4">value_of_var4</Setting>
</xsl:variable>
<xsl:variable name="mySettings"
select="msxsl:node-set($mySettings.tf)"/>

(replace msxl:node-set() with your preferred nodeset from tree fragment
function)

You can then replace references to $var_x with
$mySettings/Setting[@Name='var_1'], and to get all the values, simply
get all $mySettings/Setting.

HTH!

Dion

Subject: [xsl] concat variable names


Is there a way to concat the name of a variable?

I have 5 variables $var_1, $var_2, ..., $var_5; all declared as global
variables.
I want to use this varibles in a loop, something like this:

loop (count from 1 to 5, store the counter in a variable called
$counter)
   <xsl:variable name="newvar" select="$(concat('var_', $counter))"/>


What I want to get, is that the variable $newvar stores the value of
$var_1 and in the next run the value of $var2, and so on up to $var_5.

It does not work (of course) with the method above, but is there a way
it will work???
(It seems to me that this is a general problem in XSL, for I have other
projects where it would be very usefully too).

Thanks!
