Thanks Diogo

I tried this:

<?php
      $lotes = $pages->get(1025)->children();
      function getFirstPara($string) {
      $string = substr($string,0, strpos($string, "</p>")+4);
      return $string;
      }
      foreach ($lotes as $lote) {
      echo getFirstPara($lote->body);
      }
?>

And it worked great !!! :D

In the latest 3.x version, there's also some nice additions that will let you easily do this.

Nice. Funny that there is a regex example that seems to do what ts wants.

<?php

// render the first found paragraph only

if(preg_match('!(<p>.+?</p>)!', $value, $matches)) {

echo $matches[1];

}

Regex is basically voodoo to me so i don't quite understand the exclamation marks but i'm sure Ryan has a better grasp :)

The exclamation marks are simply pattern delimiters. Normally, this is "/", but PHP looks for the first character in a pattern string and treats it as the delimiter. This comes in handy whenever you have a pattern containing a forward slash, as you'd otherwise have to escape it to tell PHP that it's part of the pattern and not its end.

As a follow up question to the first paragraphy solutions provided. Is there a way to get "the rest of the text" output? A way to exclude the first paragraph?

The result I am looking for is to output the first paragraph from a body text field, then an image from an image field, and then the rest of the text from the body text field. So there might be other solutions?
