Counting Elements with XPath
I've been trying to figure out for the last couple of evenings how to check that a table in one of my specs has the correct amount of rows.Finally, I've found out how to do it:
it "should have 10 rows" do
html = request("/resource/with/table").body
html.should have_xpath("//table/tbody/tr[count(../*)=10]")
end
I've no idea what the "../*" means but it works!
Update:
From the interweb ( http://www.zvon.org/xxl/XPathTutorial/Output/example1.html ):
"The basic XPath syntax is similar to filesystem addressing."
So, we're going up a level (..) and selecting all tr's in tbody (*).
