How use regex for long text?

Question

I use this regex, but not work!

href="/name/nm(\d{7})\?ref.*>(.*)</a>.*class="(.*)">(.*)</span>

Link : https://regex101.com/r/JWyIJ2/1

Output:

Catastrophic backtracking has been detected and the execution of your expression has been halted. To find out more what this is, please read the following article: Runaway Regular Expressions

I recommend you launch the debugger in the menu to the left and analyze the data to find out the cause.

Show your input and expected output (Edit your question) and explain what desn't Work. — Poul Bak, Nov 06 '18 at 21:02

Don't use a regex for this. You can probably use a parser but without a description is hard to help you. — user3783243, Nov 06 '18 at 21:06

Well, have you looked at the debugger output? `.*` is usually inadvisable. — mario, Nov 06 '18 at 21:11
