[xsl] displaying selective links in ouput

["james walker" <jameswalkerandy@xxxxxxxxxxx>]

Hello,
I am stil having a bit of trouble with the selective links problem. 
Bascially i would like to display the the alpahbet at the top of the page 
and have a link (#b for example) to a letter if a title starts with it. E.g.
In this example B and D are links:
A, (B), C, (D), E.........X, Y, Z

B:
Banded substances
D:
Dont call
Dancing

I know that to take the first letter aoff teh title it would be 
<xsl:value-of select="substring(entrydata[3]/text,1,1)" />.....
At the moment i have a key <xsl:key name="ve-by-firstoccurrence" 
match="viewentry" use="substring(entrydata[3]/text,1,1)" /> which finds the 
first occurrence of a letter and groups every other title according to first 
letter..
thanks
james
