使用DOMDocument抓取数据并分类

loadHTMLFile($page_url);$div_contents = $doc->getElementsByTagName('div');print_r($div_contents);foreach($div_contents as $div_content ){    $items = $div_content->getAttribute("class");    $itme_value = $items->nodeValue;}echo $items_value;

$link[]=array();$page_url='http://smart-phones.biyixia.com/node/1013';//$content=get_data($page_url);$doc= new DOMDocument();@$doc->loadHTMLFile($page_url);$xPath = new  DOMXPath($doc);$div_tags = $xPath->evaluate("/html/body//div//@class");for($i=0;$i<$div_tags->length;$i++){    $div_tag=$div_tags->item($i);    $div_contents=$div_tag->nodeValue;    echo $div_contents;    echo "
";}

你都会xpath，还要问么？
自己用firebug或类似插件查一查就知道xpath了
