使用 Python 更改 XML 标记名称 [英] XML change tag name using Python

问题描述

对 XML 和 Python 非常陌生.我想更改 XML 文档中某些元素的标签名称.这是文档现在的样子:

Very new to XML and Python. I want to change the tag names of certain elements in an XML document. Here's how the document looks now:

<Company>
   <Employee>
      <SSN>111111111</SSN>
      <Dependent>
          <SSN>222222222</SSN>

我想将 Employee 下的标签更改为EESSN"，并使 Dependent 下的标签保持不变.看起来像这样.

I want to change the tag under the Employee to 'EESSN' and leave the tag under the Dependent the same. To look like this.

<Company>
   <Employee>
      <EESSN>111111111</EESSN>
      <Dependent>
          <SSN>222222222</SSN>

该文档包含数百家公司和数千名员工，并包含数十到数百个子元素，因此我认为我需要查找和替换选项.

The document includes hundreds of companies and thousands of employees both with tens to hundreds of sub elements, so a find and replace option is what I believe I need.

我想使用 ElementTree 模块.我唯一可以使用的代码是导入数据并将其写入新文件.感谢您的帮助！

I want to use ElementTree module. The only code I have that is working is the importing the data and writing it to a new file. Thanks for all your help!

推荐答案

如果您想使用 ElementTree，您可以找到所有 Employee 子元素的 SSN 元素和设置标签.

If you want to use ElementTree, you can find all SSN elements that are children of Employee and set tag.

示例...

输入 (input.xml)

Input (input.xml)

<Company>
    <Employee>
        <SSN>111111111</SSN>
        <Dependent>
            <SSN>222222222</SSN>
        </Dependent>
    </Employee>
</Company>

Python

import xml.etree.ElementTree as ET

tree = ET.parse("input.xml")

for elem in tree.findall("Employee/SSN"):
    elem.tag = "EESSN"

tree.write("output.xml")

输出 (output.xml)

Output (output.xml)

<Company>
    <Employee>
        <EESSN>111111111</EESSN>
        <Dependent>
            <SSN>222222222</SSN>
        </Dependent>
    </Employee>
</Company>
