python - 避免 lxml 中外部元素换行

Question

>>> from lxml import html
>>> html.tostring(html.fromstring('<div>1</div><div>2</div>'))
'<div><div>1</div><div>2</div></div>'   # I dont want to outer <div>
>>> html.tostring(html.fromstring('I am pure text'))
'<p>I am pure text</p>'  # I dont need the extra <p>

如何避免外<div>和<p>在 lxml 中？

Answer 1

默认情况下，lxml will create a parent div when the string contains multiple elements .

您可以使用单独的片段:

from lxml import html
test_cases = ['<div>1</div><div>2</div>', 'I am pure text']
for test_case in test_cases:
    fragments = html.fragments_fromstring(test_case)
    print(fragments)
    output = ''
    for fragment in fragments:
        if isinstance(fragment, str):
            output += fragment
        else:
            output += html.tostring(fragment).decode('UTF-8')
    print(output)

输出:

[<Element div at 0x3403ea8>, <Element div at 0x3489368>]
<div>1</div><div>2</div>
['I am pure text']
I am pure text
