[XSLT] Accessing contents of variable with computed name

[Christian Roth]

Hi,

how do I access the contents of a variable (or param) whose name is computed?

Pseudo-code for demonstration, NOT WORKING:

....
<xslaram name="table.frame.void">border: none;</xslaram> <xslaram name="table.frame.box">border: 1pt solid black;</xslaram> ....

<xsl:template match="table">
<table style="{$table.frame.{@frame}}"> <!-- ### -->
...
</xsl:template>

What I intend is to compute the name of the variable to be accessed using some constant prefix ('table.frame.') and the contents of the element's 'frame' attribute.

Nested {...}'s are not allowed, and some other attempts of mine did not work (like "{$concat( 'table.frame.', @frame)}").

How can I achieve this?

Answering my own question for the archive: This is not possible in XSLT.

Not exactly so:

document('')/*/xsl:variable[@name = $computedName]/@select

accesses the value of the "select" attribute of the global xsl:variable, whose name is the same as the value of the variable "computedName".

To select the children ("contents") of the same xsl:variable use the following XPath expression:

document('')/*/xsl:variable[@name = $computedName]/node
