Scrapy : ValueError: XPath error: Invalid expression


I am trying to learn scrapy for a project. I receive this error ValueError: XPath error: Invalid expression but I don't understand what is wrong in my script.

It's my script

    def parse(self, response):
        yield {
            'user_agent': str(response.request.headers['User-Agent']),
            'links' : response.xpath('//a[@class="sc-996f251d-0 leAMGT"]/@href').getall()
        }



        next = response.xpath('//a[@title="Page suivante"]/')
        print(next)

Here is a piece of the scraped page:

        <a class="indexstyles__PaginateItem-sc-8rtl5h-3 YJHOY" title="Page suivante"  href="/locations_saisonnieres/offres/p-2">

It's the error:

      ValueError: XPath error: Invalid expression in //a[@title="Page  suivante"]/

Solution

  • It seems like there is an extra '/' in your Xpath that's why it's showing an error! so instead of //a[@title="Page suivante"]/ use //a[@title="Page suivante"] and That should work!

    def parse(self, response):
        yield {
            'user_agent': str(response.request.headers['User-Agent']),
            'links' : response.xpath('//a[@class="sc-996f251d-0 leAMGT"]/@href').getall()
        }
    
    
    
        next = response.xpath('//a[@title="Page suivante"]/')
        print(next)
