I'm having trouble retrieving specific information of a string.
The string is as follows:
20190502_PO_TEST.pdf
This includes the .pdf part. I need to retrieve the part between the last underscore (_) and the dot (.) leaving me with TEST
I've tried this:
[^_]+$
This however, returns: TEST.PDF
I've also tried this:
_(.+)\.
This returns: PO_TEST
This pattern [^_]+$ will match not an underscore until the end of the string and will also match the .
In this pattern _(.+). you have to escape the dot to match it literally like _(.+)\. see demo and then your match will be in the first capturing group.
What you also might use:
^.*_\K[^.]+
^.*_ Match the last underscore\K Forget what was matched[^.]+ Match 0+ times not a dot
