Hello Jeff
Thanx for your email. 
Your code works fine. It is not exactly I need, but after a few modifications it should be ;-)
I have only one more question to you:
Is it possible to get a node, placed somewhere in my XML file during call to your template? I mean, if it is possible to call this template with for example (width,"")(height,"") nodelist (src-attribute-list) parameter and inside call a template that matches 'width' element from my XML file? (I know, that this element - like all other- is unique in my XML document scope).

Best regards
Alexandra
