如何使用PHP和SimpleXML解析名稱空間的SOAP XML響應

我正在使用CURL向Mondrian發送SOAP請求。這是PHP代碼，其中正在使用捲曲：如何使用PHP和SimpleXML解析名稱空間的SOAP XML響應

$poststring = 
    '<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" SOAP-  ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"> 
    <SOAP-ENV:Header /> 
    <SOAP-ENV:Body> 
    <Execute xmlns="urn:schemas-microsoft-com:xml-analysis"> 
    <Command> 
    <Statement> 
    select {[Measures].[Unit Sales]} on columns from Sales 
    </Statement> 
    </Command> 
    <Properties> 
    <PropertyList> 
    <Catalog>FoodMart</Catalog> 
    <DataSourceInfo>Provider=Mondrian;DataSource=MondrianFoodMart;</DataSourceInfo> 
    <Format>Multidimensional</Format> 
    <AxisFormat>TupleFormat</AxisFormat> 
    </PropertyList> 
    </Properties> 
    </Execute> 
    </SOAP-ENV:Body> 
    </SOAP-ENV:Envelope>'; 

$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, 'http://localhost:8080/mondrian/xmla'); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $poststring); 
curl_setopt_array($ch, $this->_curlOptions);   
$_rawResult = curl_exec($ch); 

curl_close($ch);

接收SOAP響應我從蒙德里安得到的是：

我的目標是提取而來的CellData元素中的所有電池元件。雖然這個迴應只有一個單元格，但有可能多個單元格有更多的答案。我想使用XPath的，但我可能會丟失與命名空間的一些詳細登記：

$xml = simplexml_load_string($_rawResponse); 
$xml->registerXPathNamespace('xsi', 'http://www.w3.org/2001/XMLSchema-instance'); 
$xml->registerXPathNamespace('cxmla', 'urn:schemas-microsoft-com:xml-analysis'); 
$_res = $xml->xpath('//CellData/Cell'); 
var_dump($_res);

的var_dump的結果是：

array(0) { 
}

，而不是像這樣：

array(1) { 
    [0]=> 
    object(SimpleXMLElement)#2 (4) { 
    ["@attributes"]=> 
    array(1) { 
     ["CellOrdinal"]=> 
     string(1) "0" 
    } 
    ["Value"]=> 
    string(4) "266773" 
    ["FmtValue"]=> 
    string(5) "266,773" 
    ["FormatString"]=> 
    string(8) "Standard" 
    } 
}

我在做什麼錯？你能指出我正確的方向嗎？先謝謝你。

如果轉儲整個解析的XML結構，您會得到什麼？你有沒有在那裏看到Cell元素？如果是這樣，它可能是你的XPath的問題;如果不是，那麼解析數據就是一個問題。 – qid 2011-12-15 18:47:35

你有沒有考慮過使用[一個合適的soap libary]（http://www.php.net/manual/en/soapclient.soapclient.php）呢？ SOAP XML從未打算直接創建或解析 - 抽象層應該自動爲您提供本機數據類型中的某些內容。如果有WSDL，你的工作會變得更加複雜.... – 2011-12-16 00:37:55

嗨，弗朗西斯。沒有WSDL，我也嘗試過在非WSDL模式下使用SoapClient，但問題會相同，因爲__doRequest方法會返回相同的XML字符串。 – 2011-12-19 17:27:30

這是一個命名空間問題。

的<root>元素，這是<CellData>元素的父，有一個默認的命名空間定義xmlns="urn:schemas-microsoft-com:xml-analysis:mddataset"所以<CellData>是在名字空間（比如它的所有後代也恰巧是）。因此，您需要註冊該名稱空間併爲其指定一些前綴，然後在XPath步驟中使用該前綴。

$xml->registerXPathNamespace('md', 'urn:schemas-microsoft-com:xml-analysis:mddataset'); 
$_res = $xml->xpath('//md:CellData/md:Cell');

如果給定元素名稱未加前綴，則XPath查詢始終搜索不在任何名稱空間中的元素。

使用DOMDocument，您可以獲取所有xml值。嘗試使用DOMDocument文檔鏈接：http://php.net/manual/en/class.domdocument.php
