I have a string variable which consists of a bunch of <p> tags as below:

<p style="text-align: center; margin: 20px">Silver Blaze</p> <p style="text-align: center; margin: 20px"> I am afraid, Watson, that I shall have to go,” said Holmes, as we
<p style="text-align: center; margin: 20px">The Naval Treaty</p> <p style="text-align: center; margin: 20px"> The July which immediately succeeded my marriage was made

I want the value of the first <p> tag in this string (Sliver Blaze in this case). I tried split with the p tag but didn't work out.
