Display first two Paragraphs

I would like to display the first two paragraphs of text from my database. Each paragraph is surrounded by <p></p> tags.

Can someone point me in the right direction please?

I had already looked at this, but struggled to see how I could get it to work...

this is what I tried;

php:
<?php   $str $row_newsRS['newsContent'];

$pattern="/(<p[^>]*>(.*)<\/p>){2}/isU";
preg_match($pattern,$str,$matches);
echo 
htmlentities($matches[0]); ?>

that should work. i just tried a test of:

<?php
$row_newsRS['newsContent'] = "<p>This is one</p><p>This is two</p><p>This is three</p>";
$str = "<p>This is one</p><p>This is two</p><p>This is three</p>";
$pattern="/(<p[^>]*>(.*)<\/p>){2}/isU";
preg_match($pattern,$str,$matches);
echo htmlentities($matches[0]);
?>

and got the desired result.

I changed it to;

php:
<?php 

$pattern
="/(<p[^>]*>(.*)<\/p>){2}/isU";
preg_match($pattern,$row_newsRS['newsContent'],$matches);
echo 
htmlentities($matches[0]);
?>



Im now getting - Notice: Undefined offset: 0 in /home/rsheep/public_html/evergreen/news.php on line 168

Im guessing that this is because this code is in a repeat region...

probably $row_newsRS['newsContent'] has a blank value when that error occurs.

this is not really something supported by the WebAssist extensions, if you need further help troubleshooting, I suggest signing up for a premiere support appointment.
