I would like to be able to use a variable to contain the number of the child I am looking for.

so for instance
I have used "//Featposition() = 4 "

I would like to be able to do something like:
"//Featposition() = myVar "

where I can assign the value to the myVar variable to be able to provide direct access to a particular node.

sorry in the above example I didn't escape the brackets
the current code is 
//Feat[position() = 4 ]


and the desired code would be
//Feat[position() = myVar ]


where I can change the value of the myVar to allow direct access to the node

For instance, in xslt, it would look like this, supposing getting the text of it.
<xsl:variable="myVar" select="4" />
<xsl:value-of select="//Feat[position()=$myVar]" />

But you might be thinking in other technologies, such as xquery... The xpath bit would still be the same.
