How to select from a string only the path to the pdf file?

Question

Regular Expressions

Good afternoon.
It is necessary that links with pdf files are searched and only the path is selected from the link.
That is, in the line href="/NanoBridgeM2/NanoBridgeM2.pdf". Find and replace /NanoBridgeM2/. We tried this: href="(.+\/)(.+\.pdf) - but in this case, the entire line is found. Please help me solve the problem.

Answer 1

and if so (\/[^\/]*\/)(.*pdf)$
and so with any nesting, you can get the name pdf (?:\/[^\/]*)*(\/.*pdf) $

Answer 2

try this href="(.+)\/([^\/]+\.pdf)"$
