I'm trying to understand how to apply a formatting directive (such as "<FONT> "</FONT>" opening and closing tags) to a DHTML text range such that the various nodes within the textrange have the formatting tags applied appropriately (basically, walking the tree). This can be tricky if the range has a table within in it, or tables in tables, because (for example) the formatting tags need to be applied around the HTML within every <TD> element in order for the formatting to render correctly within the table.
