whoo.. well that is a bit more complicated.
For each
result you have to test first
if the next paragraph bulletsAndNumberingListType is not ListType.BULLET_LIST.
if so, myResult[i].changeGrep();
Remember always to iterate your array from the back. also there are quite a bit of catches. for example if the list is the last paragraph in the story, using paragraphs.nextItem() will return a invalid object. also of notice is the fact that the"nextItem()" method on colections is horribly slow, so for a large document you ether have to writhe your own method of getting the next paragraph, or have tons and tons of patience.
if this is a one time use only script or even a rarely used script, i say it's just not worth the trouble.
