snippet 'extractH1fromContent':

<!--?php

$html = $modx--->resource->get('content');
$tag = 'h1';

preg_match_all('|<h[^>]+>(.*)</h[^>]+>|iU', $html, $headings);

foreach ($headings as $heading){
    $fullnode = isset($heading[0]) ? $heading[0] : '';
    $text = isset($heading[1]) ? $heading[1] : '';    
    if (strstr($fullnode,'h1')){
        $modx->setPlaceholder('h1.fullnode',$fullnode);
        $modx->setPlaceholder('h1.text',$text);
        $html = str_replace($fullnode,'',$html);
        break;    
    }
}

$modx->setPlaceholder('cleancontent',$html);

[[extractH1fromContent]]
[[+cleancontent]]
[[+h1.fullnode]]

WOW Bruno.

This works exactly like I imagined it would.
Thanx!
Can I make a donation somewhere?

Thank you very much for your reply Viener, but Bruno17's reply is exactly what I needed. But thanx for your time anyways..

I can go to the page from your link.
But I can't find it trough your navigation.
Maybe I'm not looking at the right place, or maybe you aren't done adding/writing....

thank you for that, I'd forgotten to edit the Menutitle!

I'm using an unpublished resource with the content structure I need, duplicating it for each recipe. I haven't gotten Content Blocks under control yet, but once I do I won't need to duplicate an already structured resource. Content Blocks will provide the sections I need - intro, question, answer, discussion.
