如何将"描述"更改为"详细信息"？

Answer 1

我建议你使用ElementTree来解析你的XML文档.

这是在python中处理XML文档的简单而最好的库.

这是一个示例代码:

import xml.etree.ElementTree as xmlParser
xmlDoc = xmlParser.parse('path to your xml doc')
rootElement = xmlDoc.getroot()

for element in rootElement.iter('description'):
    element.tag = 'details'

# Saving the xml
xmlDoc.write('path to your new xml doc')

Answer 2

那么你有两个选择。如果 xml 很小，则可以使用纯字符串替换。如果 xml 非常大，那么我建议应用 xsl 转换。
