Extracting specific data from a web page using PHP
html, php, screen-scraping
Solution
You can use `DOMDocument`, like this:
$html = file_get_contents( $url);
libxml_use_internal_errors( true);
$doc = new DOMDocument;
$doc->loadHTML( $html);
$xpath = new DOMXpath( $doc);
// A name attribute on a <div>???
$node = $xpath->query( '//div[@name="changeable_text"]')->item( 0);
echo $node->textContent; // This will print **GET THIS TEXT**
Problem
Possible Duplicate: HTML Scraping in Php I would like to know if is there any way to get from a webpage a specific string of text wich is updated every now and then using PHP. I´ve searched "all over the internet" and have found nothing. Just saw that preg_match could do it, but I didn't understand how to use it. imagine that a webpage contains this: ``` <div name="changeable_text">**GET THIS TEXT**</div> ``` How can I do it using PHP, after having used `file_get_contents` to put the page in a variable? Thanks in advance :)
