Is there a clean smooth way (preferably one line of code) to get a Node as text?
If I have a node like this:
```text/html
<node a="v">text</node>
```
, then by "clean smooth way" I mean something like:
```
void nodeAsText(Node n) {
System.out.println(n.toText());
}
```
and I expect to output:
```text/html
<node a="v">text</node>
```
