As a very quick 'off the top of my head thing' it might help to think of four cases:
Xyour textY = where X is not a [ and Y is not a ] - tag [your text] = already tagged - ignore [your textX = where X is not a ] - partial tag ignore Xyour tag] = where X is not a [ - partail tag ignore So in fact only case one is really of interest. Does that narrow down the regex pain :-) "[^\[]your text[^\]]" something like that?
