问题描述
from lxml import html
import requests
pagina = 'http://www.beleggen.nl/amx'
page = requests.get(pagina)
tree = html.fromstring(page.text)
aandeel = tree.xpath('//a[@title="Imtech"]/text()')
print aandeel
这部分有效,但我想阅读具有不同标题的多行,是否可以将Imtech"部分更改为变量?
This part works, but I want to read multiple lines with different titles, is it possible to change the "Imtech" part to a variable?
这样的事情,显然不行,但我哪里出错了?还是没那么容易?
Something like this, it obviously doesnt work, but where did I go wrong? Or is it not quite this easy?
FondsName = "Imtech"
aandeel = tree.xpath('//a[@title="%s"]/text()')%(FondsName)
print aandeel
推荐答案
你几乎是对的:
variabelen = [var1,var2,var3]
for var in variabelen:
aandeel = tree.xpath('//a[@title="%s"]/text()' % var)
