# Open a file, create a tree parser and give it the file, and retrieve
# the parsed document. Gee, this comment is longer than the code.
doc = NQXML::TreeParser.new(File.open('doc.xml')).document

# Create a writer and point it to stdout. We don't have to use the
# newline-inserting "prettify" argument here since the document
# itself contains newlines that will be output by the writer.
writer = NQXML::Writer.new($stdout)
writer.writeDocument(doc)

# The last newline, since it is outside the root entity of the document
# and is purely whitespace, is ignored by the NQXML::TreeParser. Let's
# add a newline to our output.
