java - XPath contains returning IndexOutOfBounds Exception -

-

i new xpath. following piece of code checking ? check both these class "a b" when retrieving span elements.

htmlspan resultsspan =  (htmlspan) page.getbyxpath("//span[contains(@class,'a b')]").get(0);

thanks

this xpath //span[contains(@class,'a b')]" looks span class contains substring "a b". f.e. <span class="ba ba"></span> or <span class="a b"></span> if want span class "a" or class "b" should use //span[@class="a" or @class="b")]
