how Can we get the output format to CSV instead of HTML in Alfresco using webscripts?

how Can we change the output format to CSV instead of HTML in Alfresco using webscripts?

below are the my corresponding FTL and Webscript files

recursive.get.html.ftl

<#macro recurse_macro node depth>
  <#if node.isContainer>
    <tr>
    <td> 
        ${node.properties.name}
    </td>
<td></td>
  </tr>

   <#list node.children as child>
    <#if child.isContainer>

         <@recurse_macro node=child depth=depth+1/>

 <#list child.children as child2>
    <#if child2.isDocument>
     <tr><td></td><td>${child2.properties.name}</td></tr>
       </#if>
 </#list>

    </#if>
   </#list>
  </#if>

Yes it's possible to output a csv. Refer to http://wiki.alfresco.com/wiki/Web_Scripts#Implementation

You need to change your desc file to:

 <webscript>
  <shortname>recurcive</shortname>
  <description>Recursive</description>
  <url>/sample/recursive/{recursive}</url>
  <format default="csv">extension</format>
  <authentication>guest</authentication>
 </webscript>

or if you want to mantain html as your default format you can just call the script with the csv extension (alfresco/service/recursive/blabla.csv) or with the format parameter ?format=csv

Then you have create a recursive.get.csv.ftl file like this:

    <#macro recurse_macro node depth>
      <#if node.isContainer>       
            ${node.properties.name}
       <#list node.children as child>         
         <#if child.isContainer>
         ,         
         <@recurse_macro node=child depth=depth+1/>        
          <#list child.children as child2> 
            <#if child2.isDocument>
                ${child2.properties.name}
               <#if child2_has_next>,</#if>
            </#if>
          </#list>            
         </#if>
            \n        
       </#list>
      </#if>
    </#macro>

I haven't tested the code, but i'm assuming that you understand the idea that in the end of each main node you need to break the line, and after each child (except on the last) you need a coma.

You can specify that the default output will be csv. Put this in the webscript description file (.desc.xml) extension

Then add a recursive.get.xml.ftl which will create the csv output.
