The node is text, and the DOM spec says that its name is "#text" ...
I'd suspect it's a text node with whitespace (a blank line) if the
input is your next example.  Try printing the names of each child,
and you'll probably see "#text", "line", "#text".

The next release (no, I won't say when!) should make it easier to
ignore whitespace that you really don't want to see, but which the
XML spec requires you to be able to see.  (Like that blank line.)

You'll need to get the first node that's an element, rather than
the first node ... since the first node is whitespace.

Get the (element) node whose name is "line".  Get its children.

These questions relate to DOM -- you'd surely have the same questions
with any DOM implementation!  Sun's package has no tutorial as yet,
but there are probably some on the network somewhere.
