1. 出现乱码的代码

import requestsimport refrom lxml import etreewith open('real_case.html', 'r', encoding='utf-8') as f:    c = f.read()tree = etree.HTML(c)table_element = tree.xpath("//div[@class='table-box'][1]/table/tbody/tr")#正则表达式过滤掉<>pattern1_attrib = re.compile(r"<.*?>")for row in table_element:    try:        td1 = row.xpath('td')[0]        #调用tostring()后出现乱码        s1 = etree.tostring(td1).decode('utf-8')        s1 = pattern1_attrib.sub('', s1)        print(s1)    except Exception as error:        pass

乱码：

2. 修正过后的代码
   引入HTML包，使用unescape()方法

import requestsimport refrom lxml import etree#引入HTML包import htmlwith open('real_case.html', 'r', encoding='utf-8') as f:    c = f.read()tree = etree.HTML(c)table_element = tree.xpath("//div[@class='table-box'][1]/table/tbody/tr")pattern1_attrib = re.compile(r"<.*?>")for row in table_element:    try:        td1 = row.xpath('td')[0]        s1 = etree.tostring(td1).decode('utf-8')        s1 = pattern1_attrib.sub('', s1)        # unescape() 此函数使用HTML5标准定义的规则将字符转换成对应的unicode字符。        s1 = html.unescape(s1)        print(s1)    except Exception as error:        pass

结果：
