如何在响应标记内解析包含XML文档的SOAP响应

Question

我正在向服务器发送SOAP请求并获取以下响应。我使用DDXMLParser解析响应。但是，解析器将其解释为无效的XML。我很确定<return>标记中的数据必须包含在[!CDATA]块中。当使用NSXML Parser解析时，我得到NSXMLParser Error Domain 64。 我不确定如何现在进行。

<?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

任何文档只能有一个XML声明，并且它必须位于文档的开头。

解析器会将此视为嵌套文档或不正确放置XML声明，这两者都会导致错误。

**<?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"?>**
