我正在尝试专门将 style="fill:#000000; 更改为任何其他颜色，但问题是我的 XML 文档已经有很多 (style="fill:#123456;)。我如何才能将其缩小到我需要更改或指向它的确切位置？

这是我迄今为止尝试过的python代码：

import xml.etree.ElementTree as ET
with open('test.svg','r+') as f:
    tree = ET.parse(f)
    root = tree.getroot()
    for child in root:
        child.set('fill','#777777')

Answer 1

通过查看您的文件，我猜您的元素通常位于：root[4][0]，所以试试这个（或其中的一部分）：

root[4][0].attrib['style'].split(';')[0].split('#')[1]

也可以通过id=g2348获取父元素

编辑：

root.find('./*[@id="g2348"]')[0].attrib['style']

或：

root.find('./*[@id="g2348"]')[0].attrib['style'] = 'fill:#123456;fill-opacity:1;stroke:none;stroke-width:0.001'
tree.write('test_2.svg')
