Hey all, I'm playing around with contentEditable and I'm current working with styling (bold, italic, etc...) of the current selection (window.getSelection()). Now, I know I can do this via document.execCommand (in certain browsers), but I'd like to implement my own method. I can easily apply a style node (b, i, u, etc...) to the selected text, but I also know that I need to be aware that the style may already be applied to parts of the (or the entire) selection. For instance, selecting part of a bold sentence, then applying bold to that part will result in that part being plain, and the original bold element will be broken up into 2 bold elements with textnodes, and just a textnode in between them.
So, I'm wondering if there exists a pattern for tree traversal to check for this type of thing. For those of you not familar with the Selection object, you get a startContainer and endContainer for the start and end node of the current selection, respectively. You also get a commonAncestor. All of the elements are there, I just don't want to re-invent the wheel.
