The format you've choosen looks a little bit unusual to me, because
I don't see why you drop the nesting information packed into the xml
source.
However, the following quick and dirty code may at least
be a starting point ... assuming that you've only have to deal with
valid xml (no prologue, no DTD etc.), and aren't interested in comments
or processing-instructions.
Out of your example it produces:
document: [
thexml [
tag1 [
"This is some string"
tag2 ["with embedded tags"]
"and another"
tag3 ["with this string"]
"ending with this string."
]
]
]
