Number of spaces linked to an attribute

[Paul Terray <terray@xxxxxxxxxxxx>]

Hi,

Here is a funny one : corresponding to an attribute level, I want to insert 
a certain number of spaces before the beggining of a line in HTML, i.e. :
XML :
<listing level="4">something coming from a screen</listing>

HTML (in courier):
    something coming from a screen

Since I don't know any way of making a loop, and given the fact that spaces 
do not make it in HTML, my only guess till now was (beware, this is ugly) :
<xsl:value-of 
select="substring('&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;', 
1, @level+1)"/>

Any more beautiful idea ? (this work almost, except that I get extra spaces 
sometime, if I have another markup at the beginning of the line)
