要转换为json的XML

ns1:UnderwritingRequest xmlns:xsd="" xmlns:xsi="" xmlns:ns1="ABCD" ResponseQueueName="">
  <ns1:Header>
    <ns1:TrackingId>ABCDEF</ns1:TrackingId>
    <ns1:PartnerId>Myhome</ns1:PartnerId>

在AngularJS中获取操作

var json = x2js.xml_str2json(data.XDocResponse[0]);

i / p参数包含xml，但json对象为null，我已遍历索引，xml的其他节点，但没有运气。 xml结构有什么问题吗？

请帮助我，因为我被困2天，非常感谢任何帮助
