在python中创建xml文件时如何插入制表符而不是空格

Question

我正在使用

Creating a simple XML file using python

和

inserting newlines in xml file generated via xml.etree.ElementTree in python

但是我的 xml 子元素从左到右有 2 个空格，而不是制表符，如何切换到子元素的制表符而不是 2 个空格？

Answer 1

将toprettyxml()的indent参数设置为\t：

from xml.dom import minidom
import xml.etree.cElementTree as ET

root = ET.Element("root")

doc = ET.SubElement(root, "doc")

field1 = ET.SubElement(doc, "field1")
field1.set("name", "blah")
field1.text = "some value1"

field2 = ET.SubElement(doc, "field2")
field2.set("name", "asdfasd")
field2.text = "some vlaue2"

dom = minidom.parseString(ET.tostring(root))
print dom.toprettyxml(indent='\t')

打印：

<?xml version="1.0" ?>
<root>
    <doc>
        <field1 name="blah">some value1</field1>
        <field2 name="asdfasd">some vlaue2</field2>
    </doc>
</root>
