You never need <![CDATA[]]> sections, they are just a convenience
mechanism so you don't have to escape XML's special characters &,
< and >,
<script ...><![CDATA[if (1 < 2) ...]]></script>
and
<script ...>if (1 < 2) ...</script>
are equivalent.

You could prefix the nodes with NodeX,
<text id="sampletext" y="20">Node1:
Node2:<tspan x="5" dy="1em">line 1</tspan>Node3:
Node4:<tspan x="5" dy="1em">line 2</tspan>Node5:
Node6:<tspan x="5" dy="1em">line 3</tspan>Node7:
</text>
As you can see, the text nodes that contain only white-space are nodes
too, if you just want the tspan children you could use the function
getElementsByTagNameNS() or you can iterate over the nodes and check
the node type for element nodes.
