Hello, I have a large xml file that does not have any newlines in it. Can someone please provide some code to use REXML to simply read in an xml, insert newlines after the xml sections or elements, then spit it out to stdout. This way I'd at least be able to open the xml file in an editor so I can read what kind of format it has. I don't know anything about REXML so it needs to be a somewhat complete script. thank you.
You could use HTML tidy for this I think.

You can use IO.read("somefile.xml") to read the contents into a single
string.
You can pass a file to the REXML::Document#write method instead of
$stdout, e.g.
File.open( "with_newlines.xml", "w" ){ |file|
doc.write( file, 0 )
}

Step 1) Install tidy
Step 2) tidy -i yourfile.xml
Step 3) tidy --help
REXML is very bad for handling such things.

Not at all. If you're using an an older version of the standard library, you prettify the XML using doc.write(output, 0), as in Phrogz' example.
For newer versions of REXML, use the REXML::Formatter class instead which gives you much more control over the prettifier.

Sure, i've tried for quite some time to get REXML to a point where it
really pretty-prints any document, but apart from implementing a whole
streamlistener that keeps track of indentation and width there doesn't
seem to be any. The new REXML works a bit better but inserts lots of
whitespace at the wrong places.
Unfortunately tidy has a memory-leak, so i cannot recommend the
bindings if your process is running over a longer period. Of course
you could start it in another process, but then the CLI tool is good
enough already.

Don'tunderstand what you mean by "new REXML", since you seem to be using an old one. I'm on 3.1.7.1, and here you do, for example:
formatter = REXML::Formatters::Pretty.new( 3 )
formatter.compact = true
formatter.write( doc, $stdout)

By new i mean 3.1.7 - which has formatters. But the one that ships
with ruby is still 3.1.6 - if i require a dependency then i can just
use tidy instead, no?
