Re: (anti)XMLProcessing : how to render a list of node as a comma separated list of their text ?

Hi Thierry -

Maybe I'm misunderstanding/missing something, but if your problem is  
just the whitespace (the \n s)
you could (really simplistically) just put it all on one line:

<#assign x><#list bill.material as x>${x}<#if x_has_next>,</#if></ 
#list></#assign>

(NB: not sure why you need to do the assign in your example?)

but if you want to keep it on separate lines (easier to read after  
all) then use the <#t/>  (truncate leading/trailing whitespace on this  
line):

<#assign x>
   <#list bill.material as x><#t/>
     ${x}<#if x_has_next>,</#if><#t/>
   </#list><#t/>
</#assign>
