The real problem is that the computer recognized that it is NOT a true
"Hello World" message (word, not world) and it refused to display due to
the typo ;-) just kidding.
As I recall, there's another child node in the object heiarchy when you
have text between the tags. It's a "#text" subnode to the "message"
node. Someone with more experience in that can expound.
If you use Lazarus, my TMPack has a XML Treeview component that loads an
XML file into a TTreeView for visual display. It might you help
visualize what's going on better. I've attached a tiny screenshot based
on your example XML data.

No, it returns nothing, and you'll have to look for child nodes to the
<tag> to find <inner_tag>.
The main problem is that you are thinking of an XML file as a text file,
when in fact it's a string of interconnected objects. It's kind of like
thinking of a ".frm" file textually (Is that a word) because it's stored
as a text file, when in fact it's a represenation of objects that make
up a form.
