Re: [xsl] Best way to have user decide sort

Hello Doug,

a little uncertain at what u mean by 'dynamic sort in SAX', as what u want
can be done easily in cocoon.

in any case u are going to have pass a parameter into your stylesheet
somewhere along the line to represent the decision of the user.

i would either

a) come up with some generic javascript code ( ala chris bayes stuff
www.bayes.co.uk/xml) to take care of IE or with cocoon
b) take advantage of passing params via the url ex.
http://someurl?param1=value

once u've done this u could have the xsl template call itself ( with an <a
href="someurl?param1={$somevalue}"> with just a change in the param, and
when there is some default param value, u know that no choice has been
taken.

as for dealing with the branching for PDF, this could be another param as
flag ex http://someurl?param1=value&pdf=on

HTH, jim fuller
