I am trying to get a copy-of an element by the value of one of it's
decendants. The issue is that I need to match it with a value of the a
current attribute:

following-sibling::foreign-key[child::reference/@local="the_value_of_the_current_attribute"]

Here's an example of the xml I am trying to process.

<table>
     <column name="parent_id" />
     <foreign-key>
         <reference local="parent_id" />
     </foreign-key>
</table>

I want to use the @name of the column in the xpath expression.
