[xsl] Multiple Sorts problem

[Jitu <jibhatia@xxxxxxxxxxx>]

I have following sort conditions :

                                   <xsl:sort 
select="child::node()[position() = $sortColPos]" order="{$sOrder}"/> 
                                   <xsl:sort 
select="child::node()[local-name() = $sortColName1]" order="{$sOrder}"/>
                                   <xsl:sort 
select="child::node()[local-name() = $sortColName2]" />

If $sortColPos has a valid value like 1, 2 etc.. it works.
But if does not have a valid value..for example it has a  "" or 
'1000000' (not valid for my case), then the sort conditions following it 
simply fail. They do not work.

What i want is that, if the $sortColPos has invalid value, the first 
sort should obviously not happen, but the two sorts statements following 
it should succeed.

The idea is i may either have the first SORT condition valid, OR the Two 
sort conditions following it valid. All three will never be valid. Since 
i cannot use sort statements within IF conditions...i put all of them 
one after another, assuming whichever conditio  does not satisfy, that 
sort statement will simply be ignored.

Pls let me know your valuable inputs.

Thanks.
