Preg_Match_All Help!? Argh

[jkrystof]

If anyone has some knowledge on using preg_match_all that would be greatly appreciated. I'm trying to pull some user info from my html which looks like below.

<div class="td user_ref">
	<p class="alignright" id="user">
		<span class="Height">FT</span>
		<span><span class="user_ref" userid="jbk" mwformat=",2" userfield="height1">6.3</span>
		</span>
	</p>
</div>

I am looking to pull only the 6.3 and place it into an array. I've displayed one div class but I will have between 20 to 30 html segments just like this in my complete html. Also, there are other div classes not equal to "td user_ref" within the html which should be ignored. I would like to extract each height and place it within the height array.

preg_match_all($string_pattern, $html, $height);

I've been attempting to learn the $string_pattern part with regular expressions but only getting headaches. 😕

all help and thoughts appreciated..thanks

We don't need no stinkin' regexps:

<?php
$file = "test.html";
$heights = array();
$dom = new DOMDocument();
@$dom->loadHTMLFile($file); // need "@" because your HTML is structurally invalid
$tds = $dom->getElementsByTagName('div');
foreach($tds as $td)
{
   if($td->hasAttribute('class') and $td->getAttribute('class') == 'td user_ref')
   {
      $spans = $td->getElementsByTagName('span');
      foreach($spans as $span)
      {
         if($span->hasAttribute('userfield') and $span->getAttribute('userfield') == 'height1')
         {
            $heights[] = $span->textContent;
         }
      }
   }
}
echo "<pre>";
print_r($heights);
echo "</pre>";
