Any XML-RPC fans who can help me with this please?

This label command works in the PyMOL command line:

label 4zho//A/36/CA 4zho//B/36/CA, "hello world"

How do I format an equivalent XML-RPC request?
I've tried
<methodCall>
  <methodName>label</methodName>
  <params>
    <parameter>
      <value>4zho//A/36/CA  4zho//B/36/CA</value>
    </parameter>
    <parameter>
      <value>"hello world"</value>
    </parameter>
  </params>
</methodCall>

but get back a fault response XML message with

&lt;class 'SyntaxError'&gt;:invalid syntax (&lt;string&gt;, line 1)


I have also tried encoding the " as %22, or omitting the quotes, same result.

Any ideas please?

Thanks,

Mungo
