Hi!

some short thoughts:
You need a template that matches all <trs> elements
In that template select the text node and store the text value in a variable. lets call it $key
then select /trans/tr_string[@str=$key]/ru/text()
if it isnot empty return it otherwise select the en version.
this can be done with a if then else expression

regards 
Sebastian
