SessionTransformer questions

2002-10-30 Thread Alex Romayev 
Hello,
I have a couple of questions on how to use
SessionTransformer:

1. I have a multiple select, which is being
submitted by a form, so that my request string looks
like:
my-action?selectItem=1selectItem=2selectItem=3...
 
Does anyone know how I could retrieve all of the
selectItem request paramters?  I've tried (just to
see what happens):
 
session:getxml context=request
path=/parameter/selectItem/, and this just gets the
first selectItem parameter (id=1).
 
What I would like to get is:
items
 item id=1/
 item id=2/
 item id=3/
/items
 
2. I would like to set an attribute with the value of
a request parameter.  I understand, that if I were to
set an element I would do something like:
 
item
 idsession:getxml context=request
path=/parameter/id//id
/item
 
However, what I would like to do is:
item id=the value of id request parameter/
 
Does anyone know if this is possible, or if not, what
are the typical workarounds?
 
Thanks,
-Alex

I don't know any direct working solution, but there are
some workarounds:
a) You can use a stylesheet to transform itemxyz/item
   to item id=xyz/. 
b) You can change your markup and use itemxyz/item
c) you can write a custom component for this
So you see, these are all workarounds, no real solutions.

2002-10-30 Thread Ludovic de Beaurepaire 
I did it directly in JAVA in a xsp generator, here I add in my data some
request parameters already formatted in XML :
if my request has the following parameters :
SrvImpNomMaquette=mqt1SrvImpData=data1/SrvImpNomMaquette=mqt2SrvImpData
=data2/
it generates :
maquettes
 maquette nom=mqt1
   data1/
 /maquette
 maquette nom=mqt2
   data2/
 /maquette
/maquettes

See the code below :

?xml version=1.0 encoding=ISO-8859-1?
xsp:page language=java xmlns:xsp=http://apache.org/xsp;
xsp:structure
  xsp:includejava.net.*/xsp:include

xsp:includeorg.apache.cocoon.components.language.markup.xsp.*/xsp:include

/xsp:structure

maquettes
xsp:logic
 String [] lstNomMaquette = request.getParameterValues(SrvImpNomMaquette);
 String [] lstData = request.getParameterValues(SrvImpData);
 String nomMaquette;
 String data;
 if(lstNomMaquette != null)
 {
  for(int i=0; i lt; lstNomMaquette.length; i++)
  {
   nomMaquette = lstNomMaquette[i];
   data = URLDecoder.decode(lstData[i]);

   xspAttr.addAttribute(,nom,nom,CDATA,nomMaquette);
   this.contentHandler.startElement(,maquette,maquette,xspAttr);
   xspAttr.clear();
   XSPObjectHelper.xspExpr(this.contentHandler,data);
   this.contentHandler.endElement(,maquette,maquette);
  }
 }
/xsp:logic
/maquettes
/xsp:page
