You'll need XSLT 2.0 to have a global variable or parameter in you match 
attribute.

If you don't care about namespaces (but you should):
<xsl:template match="/root/*[local-name() = $target]/child" >....

If you do care about namespaces, you can do:
<xsl:param name="target" as="xs:QName" select="xs:QName('ns:position') />

<xsl:template match="/root/*[local-name-from-QName($targer) = 
local-name() and namespace-uri-from-QName($target) = 
namespace-uri()]/child" >....


If you want to supply more than one level in the path, you should 
consider using FXSL (I believe it has some XPath parser). I also 
remember having seen some XPath parser for XSLT 2.0 on this list, but 
can't remember when.
