Todd,
Your problem is that in order to sort, you need to be able to select a
*node* for each node being sorted, whereas format-number will return you a
string. You can't select a string for processing, alas, even for purposes
of sorting by them.
I recommend a two-pass solution. In the first pass -- which will be a
near-identity transform -- decorate your data with new nodes describing
such things as the proportion between space used and total space as applied
to a given parent node. Then it'll be there in the form -- nodes -- that
your second transform wants to pick up for its sorting.
I hope this helps,
Wendell

Hello All,
I have been looking in the sorting FAQ but haven't been able to solve my
problem.
I am trying to do a sort based on a parameter which I can do ok with the
following sort statement:
<xsl:sort select="server_name[$sort='server_name'] |
nds_name[$sort='nds_name'] |
short_name[$sort='short_name'] |
total_space[$sort='total_space']"
order="{$order}" data-type="{$dtype}"/>
The above code sorts fine but I have one other sorting criteria. Based on
the used_space and total_space I figure a percent value and would like to
sort on it. The problem is I can get it to work all by its lonesome using
the following:
<xsl:sort select="format-number((number(used_space) div number(total_space))
* 100,'0')" order="{$order}" data-type="number"/>
but when I put it in with the following I get an error.
<xsl:sort select="server_name[$sort='server_name'] |
nds_name[$sort='nds_name'] |
short_name[$sort='short_name'] |
total_space[$sort='total_space'] |
format-number((number(used_space) div number(total_space))
*100,'0')[$sort='percent']"
order="{$order}" data-type="{$dtype}"/>
