Python SUDS错误 - SAXParseException

Question

有人知道在python suds调用中为什么会出现"<unknown>:1:0: syntax error"错误，即使响应看起来像这样?

<?xml version='1.0' encoding='UTF-8'?>
<env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope">
  <env:Body>
    <external.bz1:reply xmlns:abn.types="uri:abn.types.asic.gov.au" xmlns:bn.types="uri:bn.types.asic.gov.au" xmlns:business.document.header.types="uri:business.document.header.types.asic.gov.au" xmlns:external.bz1="uri:external.bz1.asic.gov.au" xmlns:fss.types="uri:fss.types.asic.gov.au" xmlns:types="uri:types.asic.gov.au">
      <business.document.header.types:businessDocumentHeader>
        <business.document.header.types:messageType>bnLodgeApplication</business.document.header.types:messageType>
        <business.document.header.types:messageReferenceNumber>1</business.document.header.types:messageReferenceNumber>
        <business.document.header.types:messageVersion>1</business.document.header.types:messageVersion>
        <business.document.header.types:senderId>ASIC</business.document.header.types:senderId>
        <business.document.header.types:senderType>GOVT</business.document.header.types:senderType>
        <business.document.header.types:messageEvents>
          <business.document.header.types:messageEvent>
            <business.document.header.types:errorCode>00007</business.document.header.types:errorCode>
            <business.document.header.types:serverityCode>Error</business.document.header.types:serverityCode>
            <business.document.header.types:description>Message previously processed but no valid reponse is available</business.document.header.types:description>
          </business.document.header.types:messageEvent>
        </business.document.header.types:messageEvents>
      </business.document.header.types:businessDocumentHeader>
    </external.bz1:reply>
  </env:Body>
</env:Envelope>

这是堆栈跟踪：

这是直接从日志中提取的，没有提到解析错误 :(

有什么想法吗？

谢谢， Ben

XML 明显是有效的。你确定它是 SAXParseException 吗？发布显示此内容的堆栈跟踪。 - Jim Garrison

我唯一的建议是传递给解析器的内容可能不完全符合您发布的内容。缓冲区开头的额外空格可能会导致此问题。 - Jim Garrison

我完全不知道该怎么办... 我粘贴的是在日志文件中显示的接收到的内容。有没有办法在解析之前删除响应中的额外空格？ - Ben Kilah

你能在调试器中运行代码以验证缓冲区内容吗？ - Jim Garrison

我不是直接传递结果，而是采取了以下措施，这样就消除了错误。

sax = suds.sax.parser.Parser()

s_received = str(client.last_received())   # passed "client.last_received()", no error 

s_parse = sax.parse(string=s_received)

而不是像这样：

x_request = eval(client.service.ListTestAccounts)

result = x_request("1")

sax = suds.sax.parser.Parser()

s_result = str(result)           # passed "result", generated error

s_parse = sax.parse(string=s_result)

希望这有所帮助。
