Search for cascading element using watin

Please tell me the way to search a cascading element in a page.

For e开发者_如何学Goxample, there are 10 anchor element tags used in a page. I can simply reach an element using FindBy method i.e. Element.FindBy(). But what to do when i have a cascading element on a page css like ".lineItem .title a"

I am not sure what you mean by saying "cascading element". Are you looking for <a/> element contained in element with class="lineItem" which is contained in element with class="title"? If so, there is at least two things you could do, to find that element:

1. Use Find.ByExistenceOfRelatedElement<T>(ElementSelector<T> selector)

   ie.Link(
       Find.ByExistenceOfRelatedElement<Element>(link => link.Ancestor(
           Find.ByClass("title")
           && Find.ByExistenceOfRelatedElement<Element>(linksAncestor => linksAncestor.Ancestor(
               Find.ByClass("lineItem"))))));
   

2. Use Predicate<Link>

   ie.Link(link =>
   {
       var ancestor = link.Ancestor(Find.ByClass("title"));
       return ancestor != null && ancestor.Ancestor(Find.ByClass("lineItem")) != null;
   });
   

I bet there is another way.
