如何使用IMPORTXML获取Google搜索的第一个结果的URL？

Question

I am trying to use the ImportXML function in Google Spreadsheets to find the URL of the first result of a Google Search (not including any links to advertised links). I thought I understood that all search results are displayed in an h3 element with class "r", and I hoped the XPath expression below would find a) all links to search results (the part in brackets) and then b) select the first one of those:

=importxml(A1,"(//h3[@class='r']/a/@href)[1]")

[where A1 is eg "="https://www.google.com/search?q=U+Chicago&num=10""]

Unfortunately I do get links to Google Maps.

Answer 1

Instead of filtering through the results, you should set google parameters to only return one result. The query parameters should include the number(num) of responses and the page (start)

"https://www.google.com/search?q=stack+overflow&num=1&start=1"

Answer 2

按相关ID缩小查询范围，例如：

//ol[@id='rso']//h3[@class='r']/a/@href

Answer 3

I've been struggling with the same thing. Haven't found a way to get a unique XPath query that only returns one URL, but you can force Google to return only the top search result!

In your search URL, change "&num=10" to "&num=1". That's it.

Answer 4

您可以同时执行两种操作，也可以使用“＆num = 1”返回一个结果，也可以使用xpath“ // cite”
