正如SaC所说。。。SimpleXml可能是这里最简单的答案

// assume $xmlstring is the xml you posted

$xml = new SimpleXmlElement($xmlstring);
$urls = $xml->xpath('//PAD_URL');

foreach($urls as $url)
{
  // when used in a string contect $url will be the text value
  echo $url;

  // however its still really the object so for example if you needed te attributes
  $attributes = $url->attributes();

}

这应该是最简单的解决方案

foreach（$xml->ITEMS->ITEMS as$Item）{echo$Item->PAD_URL；}

--hmm，蝙蝠侠！这应该是最简单的解决方案

foreach（$xml->ITEMS->ITEMS as$Item）{echo$Item->PAD_URL；}

--hmm，蝙蝠侠！或

$xml=新文档$xml->load（'file.xml'）；foreach（$xml->getElementsByTagName（'PAD_URL'）作为$PAD）{echo$PAD->nodeValue；}

或

$xml=newdomdocument$xml->load（'file.xml'）；foreach（$xml->getElementsByTagName（'PAD_URL'）作为$PAD）{echo$PAD->nodeValue；}
