python - 将xml输出到控制台(xml.etree.ElementTree)

我需要将XML打印到控制台，该控制台接收到一个响应：

import xml.etree.ElementTree as ET

xml = req.text
result = ET.ElementTree(ET.fromstring(xml))

rough_string = ET.tostring(result, "utf-8")
reparsed = minidom.parseString(rough_string)
print reparsed.toprettyxml(indent="\t")

错误：

AttributeError: 'ElementTree' object has no attribute 'tag'
  File "....", line x, in ...
    rough_string = ET.tostring(result, "utf-8")
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/xml/etree/ElementTree.py", line 1126, in tostring
    ElementTree(element).write(file, encoding, method=method)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/xml/etree/ElementTree.py", line 820, in write
    serialize(write, self._root, encoding, qnames, namespaces)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/xml/etree/ElementTree.py", line 900, in _serialize_xml
    tag = elem.tag
AttributeError: 'ElementTree' object has no attribute 'tag'

最佳答案

您正在将已创建的ElementTree对象传递回ElementTree：

result = ET.ElementTree(ET.fromstring(xml))

不要这样做；取消那里的ET.ElementTree()呼叫：

result = ET.fromstring(xml)

现在您的ET.tostring()呼叫将起作用。
接下来，我看到您正在使用req.text作为xml的源；如果这是一个requests响应对象，那么这是要传入的错误值，您应该使用req.content代替。XML解析器应该传递一个字节字符串，而不是一个unicode值。然后解析器将根据xml声明进行解码。它可能适用于只包含ascii文本的文档，但任何包含ascii字符集以外的文本的文档都将失败。
