Looking up a macro whose name is in another macro

tennenrishin

Hi RM community,

I am trying to save a given list of macros that are defined at some point in a process. The list is rather long, and I would like to set the process up in such a way that the list (of names of macros to save) appears in only one place in the XML. I thought this (followed by a Write CSV) would work:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<process version="5.3.015">
  <context>
    <input/>
    <output/>
    <macros>
      <macro>
        <key>macro1</key>
        <value>a</value>
      </macro>
      <macro>
        <key>macro2</key>
        <value>3</value>
      </macro>
      <macro>
        <key>macro3</key>
        <value>hello</value>
      </macro>
    </macros>
  </context>

</process>

but it doesn't, for some reason. Maybe I misunderstood what the "macro" function does. Could anyone point me in the right direction?

Thanks in advance,

Found a workaround: "macro()" function seems to work as expected in the Generate Macro operator.
