Question

I’m trying to match a regular expression in order to extract a value of a substring.
I’ve read on regular expression syntax but it seems I still can’t get it right.

I have the following coming from http response:

Content-Disposition:    attachment; filename=Subtitle.197747.zip; type=s
Content-Disposition:    attachment; filename="file one.txt" type=s
Content-Disposition:    attachment; filename="file one.txt"; type=s
Content-Disposition:    attachment; filename=Subtitle.197747.zip type=s

I’m trying to extract the value of filename without the double quotes if specified.
Came up with something like:

 `.*filename="?(?<filename>[^;"]*)\s?.*`

But this doesn’t seem to do the trick, would appreciate some guidance.

Thanks everyone for your answers, I read them all and went with:

filename="?(?<filename>[^;"]+)[\s;"]

Though I’m not sure how to get it to get it to compile correctly (either \s or ” giving me troubles).

Answer 1

Try this

filename="?(?<filename>[^;"]+)[;"\s]*type
