Question

我有一个像这样的xml文件：

<component apiversion="" class="BSP" condition="" group="Board" subgroup="s7g2_sk" variant="" vendor="balabala" version="1.1.1.1">
      <description>SK Board Support Files</description>
      <originalPack>board_s7g2_sk.1.3.0.pack</originalPack>
    </component>

我想提取子组值：s7g2_sk，我该怎么做？

感谢。

Answer 1

lxml库可以轻松完成此任务：

from lxml import etree

xml="""    
<component apiversion="" class="BSP" condition="" group="Board" subgroup="s7g2_sk" variant="" vendor="balabala" version="1.1.1.1">
      <description>SK Board Support Files</description>
      <originalPack>board_s7g2_sk.1.3.0.pack</originalPack>
    </component>    
"""

root = etree.fromstring(xml)
print(root.get('subgroup'))
#>>> s7g2_sk

Answer 2

或者，假设一个名为test.xml的可访问文件：

import xml.etree.ElementTree as ET
tree = ET.parse('test.xml')
root = tree.getroot()
print(root.attrib['subgroup']) # s7g2_sk

如何使用python获取xml的值？
