crawling a html page using php?
Best methods to parse HTML
I have one string-variable in my php-script, that contains html-page. How i can extract DOM-elements from this string?
For example, in this string '<div class="someclass">text</div>', i wish get variable 'text'. How i can do this?
You need to use the DOMDocument class, and, more specifically, its loadHTML method, to load your HTML string to a DOM object.
For example :
$string = <<<HTML
<p>test</p>
<div class="someclass">text</div>
<p>another</p>
HTML;
$dom = new DOMDocument();
$dom->loadHTML($string);
For example, in your case, you could use something based on this portion of code :
$xpath = new DOMXpath($dom);
$result = $xpath->query('//div[@class="someclass"]');
if ($result->length > 0) {
var_dump($result->item(0)->nodeValue);
}
Which, here, would get you the following output :
string 'text' (length=4)
Have a look at DOMDocument and DOMXPath.
$DOM = new DOMDocument();
$DOM->loadHTML($str);
$xpath = new DOMXPath($DOM);
$someclass_elements = $xpath->query('//[@class = "someclass"]');
// ...
