Hello Charlie, thank you for responding that fast.
I am trying to push my plugin l10n (http://cms4j.wordpress.com/l10n-a- jquery-plugin/) a bit further so that is does not only localize texts within the <span> elements, but also any element in a web page. Therefore i loop through all elements that have a class of "l10n" like this: $(".l10n").l10n({options}); Within the plugin in the method return this.each(function() { // do the cool stuff }); i have to decide what kind of element i am dealing with. Therefore i need the checks for the type of element. Hope that made things clearer and also hoping for your answer.
