我一直在尝试从以前保存的HTML页面中抓取信息。
我一直在与BeautifulSoup和Selenium合作，试图使它自动化。我现在正在尝试使用PC上的HTML文件，尝试从论坛中提取数据。
from lxml import html
from lxml import etree
root = etree.parse(r'C:\...\testFile.html')
tree = html.fromstring(root)
comment = tree.xpath('//*[@id="region-main"]/div/div[3]/div[1]/div[2]/div[2]/div/div/p/text()')
print (comment)
我希望从论坛中的评论以文本形式获取数据，因此以后可以将其另存为文本。
这是我删除所有个人数据后的评论示例
