在 PHP SimpleXML 对象上使用 xpath,SOAP + 命名空间(不工作..)
在 SO 和 google 上研究了几个小时之后......我希望在这里得到一些帮助:(我离运行正则表达式以完全删除命名空间仅一步之遥)
After researching this on SO and google for hours now... I hope to get some help here: (I am just one step away from running a regex to remove the namespaces completely)
首先这是 XML:
<?xml version="1.0" encoding="utf-16"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Header xmlns="http://webservices.site.com/definitions">
<SessionId>0119A|1</SessionId>
</soap:Header>
<soap:Body>
<Security_AuthenticateReply xmlns="http://xml.site.com/QQ">
<processStatus>
<statusCode>P</statusCode>
</processStatus>
</Security_AuthenticateReply>
</soap:Body>
</soap:Envelope>
现在这是我在 PHP 中的代码的样子:
Now this is what my code in PHP looks like:
$response = simplexml_load_string( $str ,NULL,
false, "http://schemas.xmlsoap.org/soap/envelope/" );
// just making sure the name space is "registered"
// but I tested all examples also with this removed
$response->registerXPathNamespace("soap",
"http://schemas.xmlsoap.org/soap/envelope/");
$_res = $response->xpath('//soap:Header');
print_r($_res);
/*** result: simple query for the root "soap" namespace, this looks good! (so far..)
Array
(
[0] => SimpleXMLElement Object
(
[SessionId] => 0119A|1
)
)
***/
// now we query for the "SessionId" element in the XML
$_res = $response->xpath('//soap:Header/SessionId');
print_r($_res);
/*** result: this does not return anything!
Array
(
)
***/
// another approach
$_res = $response->xpath('//soap:Header/SessionId/text()');
print_r($_res);
/*** result: this does not return anything at all!
***/
// Finally, without using XPath this does work
$_res = $response->xpath('//soap:Header');
$_res = (string)$_res[0]->SessionId;
echo $_res;
/*** result: this worked
0119A|1
***/
如何使用 XPATH 获取 SOAP 消息???
How can I get the SOAP message working with XPATH???
谢谢,罗马
推荐答案
多个命名空间都搞砸了,给我添加以下作品
The multiple namespaces are messing with it, adding the following works for me
$response->registerXPathNamespace("site", "http://webservices.site.com/definitions");
$_res = $response->xpath('//site:SessionId');
