如何在響應標記內解析包含XML文檔的SOAP響應

Question

我正在向服務器發送SOAP請求並獲取以下響應。我使用DDXMLParser解析響應。但是，解析器將其解釋爲無效的XML。我很確定<return>標記中的數據必須包含在[!CDATA]塊中。當使用NSXML Parser解析時，我得到NSXMLParser Error Domain 64。 我不確定如何現在進行。

<?xml version="1.0" encoding="utf-8"?> 
    <soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope"> 
     <soapenv:Body> 
      <return> 
      <?xml version="1.0"?>

Answer 1

任何文檔只能有一個XML聲明，並且它必須位於文檔的開頭。

解析器會將此視爲嵌套文檔或不正確放置XML聲明，這兩者都會導致錯誤。

**<?xml version="1.0" encoding="utf-8"?>** 
    <soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope"> 
     <soapenv:Body> 
      <return> 
      **<?xml version="1.0"?>**
