PHP简单的HTML DOM对象解码

Question

I try to do this:

$html = file_get_html ( 'http://www.ebay.com/cln/explorer/_ajax?page=1&ipp=16&catids=37958' );
foreach ( $html->find ( 'div[class="connection"]' ) as $collection ) {
    echo "found collections: ".count($collection);

Problem is, the returned file from the AJAX request contains elements encoded like:

<div class=\"collection\" data-collectionid=\"75336256016\">
<div class=\"header\">

Can anyone please help me to transform all the \" in the DOM object back to the normal ". Or change the ->find command to find the right element.

Thanks so much!

The response of the ebay is JSON, but there is a <!-- RlogId t6%60jjpfg%3C%3D%60mb6a54d.47e3-143fd4a3ae7-0x32337a --> or something like this at the end of the response.

First you need to clean up that string..

Than json_decode .. value of the html key is your html that you need to parse..

Once you cleaned up and json_decode the response the real html you looked for will be on the object named html.. take a look the code below.. I am pretty sure you can use better var names...

include('simplehtmldom/simple_html_dom.php');
$html = file_get_html ( 'http://www.ebay.com/cln/explorer/_ajax?page=1&ipp=16&catids=37958' );
$str = $html->save();


$strparts = explode('<!-- RlogId',$str);
$json = $strparts[0];


$htmlcleanedup = json_decode($json);

$domhtml = str_get_html($htmlcleanedup->html);

$ret = $domhtml->find('div[class=collection]'); 

echo count($ret);
?>
