xpath not operator and multiple select

for link in hxs.select("//a[contains(@href,'/women-')]"):
    if ('.a[notcontains(@href,"/women-shoes")]'):
        self.log("LINKS2 :: %s" % attribute::href())

The first statement is selecting all the hyperlinks which contain /women- in their url. Basically I want to select all links which have /women- in their url but not /women-shoes.

1. How can I put that condition in the for loop itself. I am looking for the correct usage of not operator in the loop condition. Also,
2. If I want to do something like select all links with /women- in their url and then in the if condition I want to check if the link doesn't have /women-shoes in the url, how do I do tha开发者_如何学编程t?

I think it would be more optimized as it will see first url not contains /women-shoes and then check whether it contains /women- :

queryStr = "//a[not(contains(@href,'/women-shoes')) and contains(@href,'/women-') ]

Why not filter within your query?

queryStr = "//a[contains(@href,'/women-') and not(contains(@href,'/women-shoes'))]"
for link in hxs.select(queryStr):
    self.log("LINKS2 :: %s" % attribute::href())
