How to Format XML Files

There are two common methods:

1. Utilize specialized tools or libraries such as XML Parser, Prettify, etc. These tools can convert unformatted XML files into formatted XML files. You can choose one of these tools and format the XML file based on the methods or API it provides.
2. Process and format XML files using a programming language. For example, using the xml.etree.ElementTree library in Python, you can load an XML file as a tree structure. After processing, you can use the tostring() method to convert the tree structure into a formatted XML string. The specific implementation code is as follows:

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

# 读取XML文件
tree = ET.parse('input.xml')
root = tree.getroot()

# 将根元素转换为字符串
xml_str = ET.tostring(root, encoding='utf-8')

# 使用minidom库进行格式化
parsed_xml = minidom.parseString(xml_str)
formatted_xml = parsed_xml.toprettyxml(indent='\t')

# 保存格式化后的XML文件
with open('output.xml', 'w') as f:
    f.write(formatted_xml)

In the code above, the XML file is first read using the ElementTree library, then converted into a string using the tostring() method. Next, the string is parsed into a DOM object using the parseString() method from the minidom library, and formatted using the toprettyxml() method. Finally, the formatted XML string is written to an output.xml file.

No matter which method you choose, you can format the generated XML file for better readability and understanding.
