I have a variable like this:
<xsl:variable name="foo">something</xsl:variable>
and I am trying to set an attribute in this way:
<disney>
<xsl:attribute name="mickey">
<xsl:value-of select="./$foo"/>
</xsl:attribute>
</disney>
where $foo is the name of an attribute of the source document.
The (wrong) output is:
<disney mickey="something">
</disney>
It's actually the correct output - it's your expectations that are
wrong. Variables in XPath hold values, they don't hold bits of
expression text. XPath is not a macro language. select="./$foo" means
exactly the same as select="$foo" - it returns the value of the variable
$foo.

while the desired one is:
<disney mickey="valueof(something)">
</disney>
Thanks for help!

P.S.
I am using XSLT and Xpath 2.0
