[xsl] Template matching attribute

["Kalyan Kumar Mudumbai" <kalyan_tech@xxxxxxxxxxxxxx>]

Hi, is there any way to invoke a template when an attribute is 
found or to write a template that matches an attribute which might 
occur in several nodes.
For example, when I am merging two files, and I have an element in 
file 1 like this.

<Currency Unit="DOL">50</Currency>

and in file 2 I have an element:

<Unit key="DOL" val="$"/>

In the output I should get it as:

<Currency Unit="$">50</Currency>

There are various such elements in File 1 and various such Key, 
value pairs in File 2. Can someone please help me out.

Thanks,
Kalyan
