XSL/XPATH compose string and use it as a variable name

[ronix]

Hi guys,

there is something i needed many times. Is it possible to compose a string and use it to call an existing variable. XPath allways see only the string.

Code: Select all

<xsl:variable name="page-width-1">

<xsl:variable name="page-width-2">

...

<xsl:variable name="page-width-n">

The the call:

Code: Select all

<xsl:variable name="result" 

select="for $tab in $schr-tabs



<xsl:value-of select="concat('$', 'page-width-', '')">

[ronix]

second try

Code: Select all

<xsl:variable name="page-width-1">

<xsl:variable name="page-width-2">

...

<xsl:variable name="page-width-n">

The call can be something like that:

Code: Select all

<xsl:variable name="result" 

              select="for $i in 1 to n 

                               return  concat('$', 'page-width-', '$i')">

or just

Code: Select all

<xsl:value-of select="concat('$', 'page-width-', '2')">

But this calls even don't work...

Hello,

No, you cannot set a variable name dynamically in XSLT. You should use one variable and compose the value based on a condition.

It may be possible to achieve what you're trying to do using a different method. Are your variables static, or obtained from fields in the source xml?
