It should be much more efficient (and probably simpler) to just traverse the DOM and replace properties in-place:

Splendid! This job gets easier by the moment!

Thanks for that.

  public void replaceProperties(Node n) throws DOMException {
    switch (n.getNodeType()) {
      case Node.ATTR_NODE:
      case Node.CDATA_SECTION_NODE:
      case Node.TEXT_NODE: {
        n.setValue(getProject().replaceProperties(n.getNodeValue()));
        break;
      }
      case Node.DOCUMENT_NODE:
      case Node.DOCUMENT_FRAGMENT_NODE:
      case Node.ELEMENT_NODE: {
        Node child = n.getFirstChild();
        while (child != null) {
          replaceProperties(child);
          child = child.getNextSibling();
        }
        break;
      }
      default: {
        // ignore all other node types
      }
    }
  }

Is there an Ant way to 'spider' a DOM node, replacing properties as it goes?

I donīt know such a thing. But you can do:
- write the DOM to a String
- use Project.replace() on that String
- parse the String
- replace the DOM with new one
