Matt,

At 12:57 PM 7/16/2003, you wrote:

OK, I was looking at using keys as well but the problem I was having (and am still having regardless of approach) is when I need to do compound matching.

I dont have an AND operator (do I?) to say I want to extract the first <B> who's substring() == val1 && substring() == val2 && substring() == val3...

I'd like the use to be multiple substring matched.

You do have an AND operator. Mysteriously, it is named "and".

But you might do as well to declare a key that has a compound value declared on the 'use' attribute. Just use the concat() function to concatenate the values you want to use, and parallel that with the analogous concat() when you call it. (Don't use the 'and' operator there: it'll return a Boolean, not the most useful of key values.)

I hope that's enough to get you going. If not, post again with more code.

Also, pay attention to other solutions suggested in this thread -- perfectly reasonable approaches there.

Cheers,
Wendell
