You can use the current() function to get the XSLT context node from within an
XPath:
<xsl:value-of
select="$documentAppConfig/configuration/myNode/@*[local-name()=current()/tex
t()]" />

> Betreff:  Fetching the value of a dynamically assigned attribute
>
> While mocking up some examples related to a previous question, I have an
> example where I add a namespace to my stylesheet and add some data to it:
>
>   <myns:data>
>     <foo>
>       <bar>one</bar>
>       <bar>two</bar>
>       <bar>three</bar>
>     </foo>
>   </myns:data>
>
> I also load another XML doc I am using data from:
>
>   <xsl:variable name="documentAppConfig"
> select="document('some_binary.exe.config')" />
>
> While looping over the elements from the data I added to my stylesheet, I
am
> trying to select the value of an attribute where the attribute name is
dynamically
> specified:
>
>     <xsl:for-each select="document('')/xsl:stylesheet/myns:data/foo/bar">
>
>         <!-- this works: -->
>         <xsl:value-of select="concat('some-text', text())" />
>
>         <!-- this does not work: -->
>         <xsl:value-of
select="$documentAppConfig/configuration/myNode/@*[local-
> name()=text()]" />
>
>         <!-- this works: -->
>         <xsl:variable name="text" select="text()" />
>         <xsl:value-of
select="$documentAppConfig/configuration/myNode/@*[local-
> name()=$text]" />
>
>     </xsl:for-each>
>
> That result is not surprising, but what is the syntactically correct way of
> accomplishing this, or is the intermediate assignment the only way?
