我有这样的页面：

我需要使用 xpath（没有命名空间）在其中查找元素。 我尝试了不同的变体，但我收到了一些非常短且空的 output（5-6 字节）：
那是我尝试过的变种。 如您所见 - 它们都不起作用。
import lxml.html as html
res = html.fromstring(sec_response.body)
len(res)
5
res.xpath('//div')
[]
import xml.etree.ElementTree as ET
xhtml = ET.fromstring(sec_response.text)
len(xhtml)
6
xhtml.xpath('//div')
*** AttributeError: 'xml.etree.ElementTree.Element' object has no attribute 'xpath'
from lxml import etree
xslt_root = etree.XML(sec_response.body)
len(xslt_root)
6
xslt_root.xpath('//div')
[]
sec_response.selector.remove_namespaces()
sec_response.xpath('//td')
[]
sec_response.xpath('//tr')
[]
请展示转换它的方法，以便 xpath 可以使用它（我需要查找 //tr 或 //td 或 //a 元素并找到它）。

scrapy shell file:///....../temp.xml # your page's code
In [1]: response.xpath('//div')
Out[1]: []
In [2]: import html
In [3]: from scrapy.selector import Selector
In [4]: response.selector.remove_namespaces()
In [5]: text = html.unescape(response.text)
In [6]: sel = Selector(text=text)
In [7]: sel.xpath('//div')
Out[7]:
[<Selector xpath='//div' data='<div id="\\\'DivPROWContainer\\\'" class=...'>,
<Selector xpath='//div' data='<div id="\\\'DivTableGCCDocsHolder\\\'" c...'>,
<Selector xpath='//div' data='<div class="\\\'PROWDefaultFooter\\\'">\\n...'>,
<Selector xpath='//div' data='<div class="\\\'PROWFooter1\\\'">© 2014-2...'>,
