Question

I have a long line like this:

<div class="interesting">This is interesting1</div><div class="not interesting">Some text</div><div class="interesting">This is interesting2</div><div class="not interesting">Some more text</div>

How can I extract the following:

This is interesting1
This is interesting2

from the above text using grep? Any suggestions?

cat temp | grep -o "<div class=\"interesting\">.*?</div>"

does not seem to be giving out anything.

Answer 1

cat temp | grep -P -o "<div class=\"interesting\">(.*?)</div>"

Parenthesis match the items items inside that html tag.
