How to add 1 line of regular expression for notepad?

Question

Regular Expressions

There is a line
href="http://web.archive.org/web/20150908161337/
I have a website, this line /20150908161337/ is different on different pages, you need to add a regular expression so that it takes into account any characters in this block and deletes this section of code. href="http://web.archive.org/web/20150908161337/so that the search and replace occurs when it finds this block, and does not change the data after it.
I wrote like this:

Answer 1

"http:\/\/web\.archive\.org\/web\/[0-9]+\/([^"]+)"// search pattern
"$1"// replace pattern
