在Python的Xpath中选择标记之间的文本

Question

<td width="250"> 10.03.1984 16:30 <br/> Lütfi Kırdar, İstanbul <br/> <br/> 47-38, 49-58, 8-10 </td>

Answer 1

"My code is mactarih=tree.xpath("//tr//td[@width='250']//text()"). But it is wrong".

如果在返回空文本或换行符以及正确文本的意义上它是“错误的”，那么您可以使用normalize-space()来过滤只包含空格的文本：

mactarih=tree.xpath("//tr//td[@width='250']//text()[normalize-space()]")

快速测试：

>>> from lxml import etree
>>> raw = '''<td width="250">
... 10.03.1984 16:30
... <br/>
... Lütfi Kırdar, İstanbul
... <br/>
... <br/>
... 47-38, 49-58, 8-10
... </td>'''
>>> root = etree.fromstring(raw)
>>> root.xpath("//td[@width='250']//text()[normalize-space()]")
['\n10.03.1984 16:30\n', u'\nL\xfctfi K\u0131rdar, \u0130stanbul\n', '\n47-38, 49-58, 8-10\n']
