Question

Could someone show me a regular expression that would look through this document and select the href value of every href that has RELATION_ID on the end of it? Then if it does, I have to get the Id that is before the question mark (example href='dctm://ISDOFSDdev/37004e1f800021f3?DMS_OBJECT_SPEC=RELATION_ID‘)

Thanks!

Answer 1

You can use this regex expression:

[a-fA-F0-9]+(?=\?DMS_OBJECT_SPEC=RELATION_ID) 

which matches the the hex number immediately before the query string.

I’d also suggest using XPath to do this over regex.
