Question

I want this code to check if a element exists and then get the number of records inside the div.

html

<div id=myDiv>This table contains 5 records (3 seconds)</div>

php

$selector = new Zend_Dom_Query($response->getBody());
$nodes = $selector->query('#myDiv');

if (count($nodes) < 1) {
            $this->setValue(0);
            return;
        }

        $el = $nodes->current();
        if (preg_match('#(\d+[\d,]*)\s+result#i', $el->nodeValue, $matches)) {

            $number = str_replace(',', '', $matches[1]);
            $this->setValue(intval($number));
        } else {
            Zend_Registry::get('log')->err(get_class($this).': Unable to match response and regex.');
            $this->setValue(0);
        }

Right now it gets to the bottom $this->setValue(0), so it can find the element. There must be something wrong with the regex, and that’s where Im clueless.

if (preg_match('#(\d+[\d,]*)\s+result#i', $el->nodeValue, $matches)) {

The HTML code does not contain anything that would match #(\d+[\d,]*)\s+result#i, the expression requires the string “result” to be present.

You probably want to change that word to “record”. E.g:

/(\d+)\s+record/i
