How to simply parse and print the XML with dxml?

[tastyminerals via Digitalmars-d-learn]

Maybe I missed something obvious in the docs but how can I just 
parse the XML and print its content?

```
import dxml.parser;
auto xml = parseXML!simpleXML(layout);
xml.map!(e => e.text).join.writeln;
```

throws 
`core.exception.AssertError@../../../.dub/packages/dxml-0.4.3/dxml/source/dxml/parser.d(1457): text cannot be called with elementStart`.
