Json to XML with namespaces

hello,

I’m new to streamsets so it might be an obvious question!

I’m using “data generator” to accept the json input and transform to XML, however I want to add few namespaces in the generated XML output. Please can anyone suggest how to achieve that?

This is the output “data generator” is producing:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<root>
  <id>file</id>
  <value>File</value>
  <popup>
    <menuitem>
      <value>New</value>
      <onclick>CreateDoc()</onclick>
    </menuitem>
    <menuitem>
      <value>Open</value>
      <onclick>OpenDoc()</onclick>
    </menuitem>
    <menuitem>
      <value>Save</value>
      <onclick>SaveDoc()</onclick>
    </menuitem>
  </popup>
</root>

What changes do I need to make it something like this (the element id is under “b” namespace):

<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<root xmlns:b="http://bookstore.com/books">
  <b:id>file</id>
  <b:value>File</value>
  <popup>
    <menuitem>
      <value>New</value>
      <onclick>CreateDoc()</onclick>
    </menuitem>
    <menuitem>
      <value>Open</value>
      <onclick>OpenDoc()</onclick>
    </menuitem>
    <menuitem>
      <value>Save</value>
      <onclick>SaveDoc()</onclick>
    </menuitem>
  </popup>
</root>
