PHP解析XML内容

Question

这是我的请求发送

$header = "POST 213.207.000.000/services/AmountCharging/v3 HTTP/1.1 \r\n"; $header .= "Content-type: text/xml;charset=UTF-8 \r\n"; 
$header .= "Content-length: ".strlen($request_xml)." \r\n"; 
$header .= "Content-transfer-encoding: text \r\n"; 
$header .= "Connection: Keep-Alive \r\n\r\n"; 
$header .= $request_xml; 
$ch = curl_init(); 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); 
curl_setopt($ch, CURLOPT_URL,$url); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_TIMEOUT, 120); 
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $header); 
$strxml = curl_exec($ch); 

下面是我的XML响应，并使用PHP我要抢的<soapenv:Body></soapenv:Body>

<?xml version="1.0" encoding="utf-8" ?> 
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> 
<soapenv:Body> 
<ns1:chargeAmountResponse xmlns:ns1="http://www.csapi.org/schema/parlayx/payment/amount_charging/v3_1/local"></ns1:chargeAmountResponse> 
</soapenv:Body> 
</soapenv:Envelope> 

任何想法，只是内容？ 谢谢..

鉴于在soapenv:Body内确实没有什么值得一看的，下面并没有真正显示任何有趣的内容，但应该有所帮助。

$strxml='<?xml version="1.0" encoding="utf-8" ?> 
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> 
    <soapenv:Body> 
     <ns1:chargeAmountResponse xmlns:ns1="http://www.csapi.org/schema/parlayx/payment/amount_charging/v3_1/local"></ns1:chargeAmountResponse> 
    </soapenv:Body> 
</soapenv:Envelope>'; 

$dom=new DOMDocument; 
$dom->loadXML($strxml); 
$body=$dom->getElementsByTagNameNS('http://schemas.xmlsoap.org/soap/envelope/','Body')->item(0); 
echo 'Body: '.$body->tagName.', Child: '.$body->childNodes->item(1)->tagName.', Attribute: '.$body->childNodes->item(1)->getAttribute('xmlns:ns1'); 


Output 
------ 
Body: soapenv:Body, Child: ns1:chargeAmountResponse, Attribute: http://www.csapi.org/schema/parlayx/payment/amount_charging/v3_1/local 


update: 
------- 

Given that it does appear supplying a single line string causes errors 
you could aproach it slightly differently. 

$col=$dom->getElementsByTagName('*'); 
foreach($col as $node) { 
    echo 'tag:'.$node->tagName.' value:'.$node->nodeValue.BR; 
}
