我正在尝试使用此代码解析网页。
ac = requests.get('link....')
html_text = ac.text
lx = html.fromstring(html_text)
当我运行此代码时，我收到此错误
Traceback (most recent call last):

我找到导致错误的html标记：
<ie:menuitem id="MSOMenu_Help" iconsrc="/_layouts/images/HelpIcon.gif" onmenuclick="MSOWebPartPage_SetNewWindowLocation(MenuWebPart.getAttribute('helpLink'), MenuWebPart.getAttribute('helpMode'))" text="Help" type="option" style="display:none">
</ie:menuitem>
答案 0 :(得分：0)
您发现HTML标记出现了错误，但是您确定了吗？如果没有试试这个：
ac = requests.get('link....')
lx = html.fromstring(ac.content)
valueOfHTMLTag = lx.xpath('//TAG[@class/id="Name"]/text()')
你改变的地方：
这将返回一个数组，其中包含具有正确class / id的标记值。
希望这有帮助！
