Using <xsl:for-each> and position() to increase indent in each iteration

Hi,

I'm new to the list and fairly new to XSL.

I am wanting to use the position() function to increase the indent in an 
<xsl:for-each> iteration by 3 spaces, using the following logic, but preferably 
without using a case statement:

position() == 1 > generate ""
position() == 2 > generate "&nbsp;&nbsp;&nbsp;"
position() == 3 > generate "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"
position() == 4 > generate 
"&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"
etc
etc

As a separate issue, when I use &nbsp; in my xsl template it seems to fail (the 
&nbsp; disappears).

By googling I found a suggestion to use &#160; instead.

Is there a reason why &nbsp; is not working?

Thanks very much,

David Gadd
