Regex select all text between tags

You can use "<pre>(.*?)</pre>", (replacing pre with whatever text you want) and extract the first group (for more specific instructions specify a language) but this assumes the simplistic notion that you have very simple and valid HTML.

As other commenters have suggested, if you're doing something complex, use a HTML parser.

Tag can be completed in another line. This is why \n needs to be added.

<PRE>(.|\n)*?<\/PRE>
