Class::XPath has turned out to be a very good idea, if I may say so myself. Just now I was working on a change to a Krang element library and Class::XPath saved me a lot of work. I needed to reorganize the element tree and move a subelement one level deeper. Without Class::XPath the code to access this element would probably have been:
$auto = $story->element->child('search_auto');Which would have to change to:
$auto = $story->element->child('search_auto_container')->child('search_auto');This would have sucked because that element is used all over the element set. But thanks to Class::XPath the code was:
($auto) = $story->element->match('//search_auto');This will work no matter where the 'search_auto' element is in the tree, so no change is needed! How cool is that?
