Reg : Facing problem in removing duplicates.

Hai ,

Herewith I have attached the input xml and expected output as jpeg image. I
am facing the problem with Footnote (removal of duplicates).

I.e( Though we have one or more occurance of  *'*'* or *'**'* or *'****' in
input xml , the footnote must contain only one occurance of each followed by
 "*per N ordinary share"*
**
*Example :*
* * per N ordinary share*
 * ** per N ordinary share*
 * *** per N ordinary share*

Please help me on this.

Thanks in advance.

regards,
