I assume you mean that it's giving you only the first line of text of
each node.

"(.*)" will capture a single (and possibly empty) line of text.

"(.+\n)" will capture a single non-empty line of text ending with a
newline.

I think you want to capture multiple non-empty lines, each line ending
with a newline:

patternNode = re.compile("""
# Node (\w*).*
((?:.+\n)*)""", re.MULTILINE)

It's better than my Czech/Slovak (depending on what Google says)! :-)
