[User feedback required] How to name the file with only the alphanumeric characters of the url

[Sekuiya]

So, I'm a beginner in this whole regular expression deal, but here's my problem.

I need to name my files in according to their source urls, more specifically I need to remove all non-alphanumerics characters.

An example:
I have this file

**External links are only visible to Support Staff**

and I need it's filename to be

httpsdrivegooglecomucexportdownloadid14YrfZFcr07ZOrBauATKS4Mg0pE66.png

.

Looking up online sites I was able to reach at this regular expression that would match all my desired characters, "([^\W_])". Now my problem is transferring this to the file name.

I was using "<jd:source:1>.<jd:orgfiletype>" but this unfortunately only gives me a "h.png". I tried looking some kind of tutorial but all I could find of <jd:source:1> was answers in the forums so I've reached a wall.

Any help would be appreciated, thank you very much!

your first regex condition only repeats for single character hence why just h is returned, use + as repeat. not sure you can achieve your desired outcome to be honest, since you don't exactly know how many times its going to repeat. For instance how many / and ? (illegal chars). Since you need to do jd:source:x for each repeat. either you need to create many rules to cover said repeats, or it might be easier to achieve with eventscripter (javascript) extension module.
