我正在向服务器发送 SOAP 请求并获得以下响应。我正在使用 DDXMLParser 解析响应。但是，解析器将此解释为无效的 XML。我很确定<return> 标签内的数据必须包装在[!CDATA]块中。使用NSXML Parseri am getting解析时NSXMLParser Error Domain 64。我不确定现在如何进行。

    <soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope">
      <soapenv:Body>
          <return>

任何文档只能有一个 XML 声明，并且必须位于文档的开头。

解析器会将此视为文档的嵌套或 XML 声明的不正确放置，这两者都会导致错误。
