数据文件testfile.xml是这样的：
<?xml version="1.0" encoding="utf-8"?>
<body>
<body.head>
<hedline>
<hl1 style="header">All the things we lost that summer</hl1>
<hl2 style="standfirst">It was the promise of seals that sold Virginia on this mission.</hl2>
<hl2 style="dropcap-large"><em class="dropcap">W</em>e are always calling each other names.</hl2>
</hedline>
</body.head>
</body>
解析该文件的脚本是这样的：
import xml.etree.ElementTree as ET
tree = ET.parse('testfile.xml')
root = tree.getroot()
if root.find('body.head') is not None:
if root.find('body.head').find('hedline') is not None:
for child1 in root.find('body.head').find('hedline'):
print("Tag level 1:" + child1.tag)
print("Attrib level 1:" + str(child1.attrib))
print("Text level 1:" + str(child1.text) + "\n")
for child2 in child1:
print("Tag level 2:" + child2.tag)
print("Attrib level 2:" + str(child2.attrib))
print("Text level 2:" + str(child2.text))
这就是结果：
Tag level 1:hl1
Attrib level 1:{'style': 'header'}
Text level 1:All the things we lost that summer
Tag level 1:hl2
Attrib level 1:{'style': 'standfirst'}
Text level 1:It was the promise of seals that sold Virginia on this mission.
Tag level 1:hl2
Attrib level 1:{'style': 'dropcap-large'}
Text level 1:None <-- THIS IS THE PROBLEM
Tag level 2:em
Attrib level 2:{'class': 'dropcap'}
Text level 2:W
我希望报告行“文本级别 1：”报告值“e 总是互相称呼对方的名字”。来自数据文件，但它无法解析它，因此它最终为 None。 你能正确解析它吗？ 这是 Windows 上的 Python 3.12。
