插入带有LXML的元素，并设置属性和文本

Question

我想多次插入具有相同标记的元素，每次使用LXML插入不同的内容和属性。虽然插入元素很容易，但如何获取新创建的元素来设置其文本和属性呢?

text = ['First', 'Second', 'Third']
for i, t in enumerate(text):
parent.insert(i, etree.Element('tspan')
# Now, what object should I use to set text and attrib?

Answer 1

使用ElementTree(不需要外部库)

import xml.etree.ElementTree as ET
xml = '''<root></root>'''
text = ['First', 'Second', 'Third']
root = ET.fromstring(xml)
for txt in text:
sub = ET.SubElement(root,'tspan')
sub.text = txt
ET.dump(root)

输出

<?xml version="1.0" encoding="UTF-8"?>
<root>
<tspan>First</tspan>
<tspan>Second</tspan>
<tspan>Third</tspan>
</root>
