The code below does not work right when I get in line with multiple spaces

The code below does not work right when I get in line with multiple spaces:

RadDocument doc = new RadDocument();

.......

In the document have the following line:

" *                *                *               *              *                *     "

And the command does not work when running "while" in order to exclude the entire line:

doc.delete(true);     

Nor can I run this command "deleterange" in line
