Dear R-list,
I am looking for a way to efficiently read a text file (see example below)
into a nested list. I can probably find an ugly way to do this, but I would
appreciate if anyone has (ideas for) efficient solutions.
It seems to me this is a bit similar to parsing XML, could tools from the
XML package be used/changed to read custom files like these?
thanks!

## Text file looks like, for example:
txt <-
"treelist {
Node {
sometext
}
Node {
some more text
}
Node {
Component {
some component
with more text lines
}
Component {
another one
}
Node {
a sub node
}
}
}"
## The result should look like :
# (extra points for naming the elements of the list, but not necessary!)
> treelist
[[1]]
[1] "sometext"
[[2]]
[1] "some more text"
[[3]]
[[3]][[1]]
[1] "some component
[2] "with more text lines"
[[3]][[2]]
[1] "another one"
[[3]][[3]]
[1] "a sub node"
