Getting Data Between Elements in Nokogiri

Question

I'm trying to get the text between two elements in nokogiri and pair the data with the text in the element in front of it.

html  = 
"<website>
    <maindeck>
        1<card>Blood Crypt</card>
        2<card>Temple Garden</card>
    </maindeck>
    <maindeck>
        3<card>Angel of Serenity</card>
        4<card>Forest</card>
    </maindeck>
</website>"

I want to end up with an array like this

#=> [[1,"Blood Crypt"],[2,"Temple Garden"]]

A previous example provided this as an answer, but I'm unsure of what it does/ how to use it.

/*/div[1]/following-sibling::text()[1]

Answer 1

This works:

doc = Nokogiri::HTML(html)
doc.xpath('//maindeck[1]/text()').map { |n| [n.text.to_i, n.next.text] }
#=> [[1, "Blood Crypt"], [2, "Temple Garden"]]
