How to rip out an attribute using a regular expression?

Question

Regular Expressions

There are a bunch of links with attributes, I need to rip out the title attribute. I didn’t work much with regular expressions, I only googled it.
(?<=\btitle=")[^"]*
But in this way I delete the contents of the attribute, but I need to somehow invert the work of this expression. Help brotherly please.

At the exit, you need only
