将xml打印到控制台(xml.etree.ElementTree)

Question

我需要将xml打印到我从响应中收到的控制台:

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'

Answer 1

您正在将已创建的ElementTree对象传递回ElementTree:

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

不要那样做; 删除ET.ElementTree()那里的电话:

result = ET.fromstring(xml)

现在你的ET.tostring()电话会工作.

接下来,我看到您正在使用req.textXML作为源代码; 如果那是一个requests响应对象,那么传入的值是错误的,你应该使用它req.content.XML解析器应该传递一个字节字符串,而不是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,但包含ASCII字符集之外的文本的任何内容都将失败.
