将elementtree转储到xml文件中

Question

我用这样的东西创建了一个xml树

top = Element('top')
child = SubElement(top, 'child')
child.text = 'some text'

如何将其转储到XML文件中？我试过了top.write(filename),但方法不存在.

您需要实例化一个ElementTree对象并调用write()方法:

import xml.etree.ElementTree as ET

top = ET.Element('top')
child = ET.SubElement(top, 'child')
child.text = 'some text'

tree = ET.ElementTree(top)
tree.write('output.xml')

output.xml运行代码后的内容:

<top><child>some text</child></top>
