【问题描述】：

我编写这个 python 脚本是为了创建 Xml 内容，我想把这个“美化”的 xml 写入一个文件（完成 50%）：

到目前为止我的脚本：

    data = ET.Element("data")

    project = ET.SubElement(data, "project")        
    project.text = "This project text"

    rawString = ET.tostring(data, "utf-8")
    reparsed = xml.dom.minidom.parseString(rawString)

    cleanXml = reparsed.toprettyxml(indent="    ")

    # This prints the prettified xml i would like to save to a file
    print cleanXml

    # This part does not work, the only parameter i can pass is "data"
    # But when i pass "data" as a parameter, a xml-string is written to the file
    tree = ET.ElementTree(cleanXml)
    tree.write("config.xml")

当我将 cleanXml 作为参数传递时出现的错误：

Traceback (most recent call last):
  File "app.py", line 45, in <module>
    tree.write("config.xml")
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/xml/etree/ElementTree.py", line 817, in write
    self._root, encoding, default_namespace
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/xml/etree/ElementTree.py", line 876, in _namespaces
    iterate = elem.getiterator # cET compatibility
AttributeError: 'unicode' object has no attribute 'getiterator'

有人知道我如何将美化的 xml 保存到文件中吗？谢谢和问候！

【解决方案1】：

ElementTree constructor 可以传递根元素和文件。要从字符串创建ElementTree，请使用ElementTree.fromstring。

但是，这不是您想要的。只需打开一个文件，直接写入字符串即可：

with open("config.xml", "w") as config_file:
    config_file.write(cleanXml)
