我只想返回其中父标题节点中包含匹配文本的xml部分,在此示例中,要匹配的文本是“site”.

//get Feed with curl

 $doc = new SimpleXmlElement($xml,LIBXML_NOCDATA);

 //$result = $doc->xpath('//title'); //this works returns all the <title>'s

 $result = $doc->xpath('//title[site]');                     //doesn't work
 $result = $doc->xpath('//title[text()="site"]');           //doesn't work
 $result = $doc->xpath('//title[contains(site)]');           //doesn't work
 $result = $doc->xpath('//title[contains(text(),'Site')]');  //doesn't work


 foreach ($result as $title)
 echo "$title<br />"
