Getting post count

[Martin18]

I'm working on something and I need to be able to grab post count from another forum.

 

I looked into regex and I'm really clueless.

 

<div class='row1' style='padding:6px; margin-bottom:1px; padding-left:10px'>1,856 posts (14.15 per day)</div>

 

The posts are displayed like that.. how would I go about retrieving just the "1,856 posts (14.15 per day)" part.

 

I was thinking you could just get whatevers between <div class='row1' style='padding:6px; margin-bottom:1px; padding-left:10px'> and </div> but that's not the only text between html like that.

One method (and is an alternative to regex) would be to make use of dom / domxpath like so:

 

$html = <<<EOF
   <div class='someCrap'>whatever</div>
   <div class='row1' style='padding:6px; margin-bottom:1px; padding-left:10px'>1,856 posts (14.15 per day)</div>
   <div class='someCrap'>whatever</div>
EOF;

$dom = new DOMDocument;
libxml_use_internal_errors(true);
@$dom->loadHTML($html); // for a live site, change @$dom->loadHTML to @$dom->loadHTMLFile and put url in quotes within the parenthesis
libxml_use_internal_errors(false);
$xpath = new DOMXPath($dom);
$divTag = $xpath->query('//div[@class = "row1"]');

foreach ($divTag as $val) {
    echo $val->nodeValue . "<br />\n";
}

//Output: 1,856 posts (14.15 per day)

 

EDIT: Granted, this makes some very rudimentary assumptions (like looking for a div with the class = "row1"). This may be too 'loose fisted' with regards to control. I guess it entirely depends on the html div possibilities. So this solution may (or may not) offer enough control to distinguish which divs exactly you are looking at.
