how to cast a variable in xpath python

Question

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

This part works, but I want to read multiple lines with different titles, is it possible to change the "Imtech" part to a variable?

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

Answer 1

You were almost right:

variabelen = [var1,var2,var3]
for var in variabelen:
    aandeel = tree.xpath('//a[@title="%s"]/text()' % var)
