如何在xpath python中转换一个变量 [英] how to cast a variable in xpath python

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)
