[F8] Add/remove bullets in html selection??

I've got a text field that I need to be able to add and remove bullets from using the <li> html tag. I figured out how to get the selection and wrap it with the <li> tag, but, I'm not sure how to determine if there's an <li> tag around the selection html and remove it. I would just do a split and join to remove the tags from the whole text box, but there might be two bulleted sections on one page, so I can't just remove all the bullets...

Anyone??

Sample attached...

Edit: And here's the code I'm using...as you can guess, the first part of the if statement isn't working since the <li> tag doesn't show up in the selection, since it's not html:

Code:

---

on (release) {
        Selection.setFocus(this._parent.text_txt.text);
        Selection.setSelection(this.SelBegin, this.SelEnd);
        allText = this._parent.text_txt.text;
        selText = allText.substring(this.SelBegin, this.SelEnd);
        if (selText.substring(1, 4) == "<li>") {
                initString = this._parent.text_txt.text.substring(0, this.SelBegin);
                replaceString = selText.substring(5, selText.length-5);
                finalString = this._parent.text_txt.text.substring(this.SelEnd, this._parent.text_txt.text.length);
                this._parent.text_txt.htmlText = initString+replaceString+finalString;
        } else {
                initString = this._parent.text_txt.text.substring(0, this.SelBegin);
                replaceString = "<li>"+this._parent.text_txt.text.substring(this.SelBegin, this.SelEnd)+"</li>";
                finalString = this._parent.text_txt.text.substring(this.SelEnd, this._parent.text_txt.text.length);
                this._parent.text_txt.htmlText = initString+replaceString+finalString;
        }
}
