Using the collector node to generate XML

README.md

This flow is an example of using the collector node type which can be found here: https://www.npmjs.org/package/node-red-contrib-collector

After pressing the a, b and c inject buttons, the following XML is output in the debug tab:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<root>
  <a>Value A</a>
  <b>Value B</b>
  <c>Value C</c>
</root>

Pressing the no b button causes the <b>Value B</b> element to be removed again.
