ElementTree 文本与标签混合

Question

想象以下文字：

<description>
the thing <b>stuff</b> is very important for various reasons, notably <b>other things</b>.
</description>

我如何设法使用 etree 接口解析它？有了 description 标签，.text 属性 returns 只有第一个词 - the。 .getchildren() 方法 returns <b> 元素，但不是文本的其余部分。

非常感谢！

Answer 1

获得.text_content()。使用 lxml.html:

的工作示例

from lxml.html import fromstring   

data = """
<description>
the thing <b>stuff</b> is very important for various reasons, notably <b>other things</b>.
</description>
"""

tree = fromstring(data)

print(tree.xpath("//description")[0].text_content().strip())

打印：

the thing stuff is very important for various reasons, notably other things.

I forgot to specify one thing though, sorry. My ideal parsed version would contain a list of subsections: [normal("the thing"), bold("stuff"), normal("....")], is that possible with the lxml.html library?

假设描述中只有文本节点和 b 元素：

for item in tree.xpath("//description/*|//description/text()"):
    print([item.strip(), 'normal'] if isinstance(item, basestring) else [item.text, 'bold'])

打印：

['the thing', 'normal']
['stuff', 'bold']
['is very important for various reasons, notably', 'normal']
['other things', 'bold']
['.', 'normal']
