Get text between H2 tags

I want to get text between < H2 > tags . The code I wrote was

grep -oP  "<H2>.*?</H2>" redirect.html

The answer I get is

<H2><A NAME="s3">3. All about redirection</A>        </H2>

I want to remove the < H2 > and < /H2 > by changing the regular expression there.

>Solution :

Try using this,

grep -oP  "(?<=<H2>).*?(?= </H2>)" redirect.html
