Extracting specific data from a web page using PHP [duplicate]

Answer 1

You’re talking about data scraping: the act of extracting data from a human readable output. In your case this is whatever is between the <div> tags. Use PHP DOM’s extension to get to the tag you want and extract data. Google search for a PHP DOM tutorial.

Answer 2

You might want to have a look at the

Simple HTML DOM Library

There is a little tutorial here: http://www.developertutorials.com/tutorials/php/easy-screen-scraping-in-php-simple-html-dom-library-simplehtmldom-398/

That one is a screen scraping API that lets you feed html to it and then get parts of it in a jQuery similiar language.

Answer 3

$delements= file_get_html('url will go here'); 

foreach($elements->find('element') as $ele) {

    //traverse according to your preferences

} 

//return or output

Answer 4

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**
