这里使用的是xpath这个第三方python库
使用 from lxml import etree 导入
使用:
select = etree.HTML(html)
content = select.xpath()
for each in content:
print each
一个简单的demo:
from lxml import etree html = ‘‘‘ <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <input id=‘name1‘ href = ‘www.hao123.com‘></input> <input id=‘name2‘></input> xxxx </body> </html> ‘‘‘ select = etree.HTML(html) content = select.xpath("//body/input[@id=‘name1‘]/@href") for each in content: print each print "end"
