| First, we print out the document tree with a |
| recursive Velocimacro : |
| |
| #recursive( $root.getRootElement() $i ) |
| |
| |
| Next, we access pieces of data directly : |
| |
| email : $root.getRootElement().getChild("properties").getChild("author").getChild("email").getText() |
| last name : $root.getRootElement().getChild("properties").getChild("author").getChild("name").getChild("last").getChild("full").getText() |
