Giving values to xsl:variable by xml attribute

How do I set a value of a variable by attribute?

Let's say I want to determine the value of a variable from a list by node
name (I have the static names in advance):

This is my static xsl tree
<xsl:variable name="values">
	<one>1</one>
	<two>2</two>
</values>

This is the input xml:
<x value="one"/>

and now I want to access it in the xsl:

.
.
.
<xsl:value-of name="$values/one"/>

This will work, but what if I want the "one" node to be determined by the
xml value?
