Hi there,

I'm fairly new to workflow and haven't tried pattern matching yet, but I have a project which asks me to parse out the strett number from a file name and assign it to a field value.  The file names look like this:

SR_A_G_ANDES DR 120.pdf

I'm trying to just parse out the street number, so only the numbers that occur right before the ".pdf".  They are separated from the rest of the file name by a white space that occurs right before the number.  I know that  (.*).pdf will get everything before the .pdf extension, but how do I make it stop at the white space that occurs directly before that number (like, everything to the left of the '.pdf' but stop at the first white space it gets to)? 

I've built a few workflows now, but this is my first foray into pattern matching, and I'm finding it challenging.  I will be looking into more training now for sure, but I really need to get this one off the ground. Can someone help?

Would this work?

Thanks so much!
