Question

Trying to find all HTML <table> rows with this operator, but nothing:

preg_match_all("#<tr[^>]*>.*</tr>#", $content, $matches);

what’s wrong?

Answer 1

Any regex will have trouble with nested tables, unless you get into complicated recursive expressions.

Try this instead:

$dom = new DOMDocument();
$dom->loadHTML($content);
$matches = $dom->getElementsByTagName("tr");
$count = $matches->length;
