Extract XML Element Values

I have a rather large file with XML-style content. Each line contains one full XML entry. For example:

1:<Message><DNIS>1234</DNIS><UCID>3456</UCID><TransferGroup>XYZXYZ</TransferGroup></Message>
2:<Message><DNIS>9999</DNIS><UCID>2584</UCID><TransferGroup>ABCABC</TransferGroup></Message>
.....

I'm trying to figure a way to be able to go through the file, pull pertinent info, and print the output in a separate file delimited with commas:

output.txt:
1234,3456,XYZXYZ
9999,2584,ABCABC

I was able to achieve this via a series of greps with cuts for each value I want, but it takes far too long to run. I have 10,000+ entries to retrieve. I'm not very good with awk or sed or anything else that could prove more efficient. Can anyone help? Thanks!

NAME
XML::Handler::CanonXMLWriter - output XML in canonical XML format SYNOPSIS
use XML::Handler::CanonXMLWriter; $writer = XML::Handler::CanonXMLWriter OPTIONS; $parser->parse(Handler => $writer); DESCRIPTION
"XML::Handler::CanonXMLWriter" is a PerlSAX handler that will return a string or write a stream of canonical XML for an XML instance and it's content. "XML::Handler::CanonXMLWriter" objects hold the options used for writing the XML objects. Options can be supplied when the the object is created, $writer = new XML::Handler::CanonXMLWriter PrintComments => 1; or modified at any time before calling the parser's `"parse()"' method: $writer->{PrintComments} = 0; OPTIONS
IOHandle IOHandle contains a handle for writing the canonical XML to. If an IOHandle is not provided, the canonical XML string will be returned from `"parse()"'. PrintComments By default comments are not written to the output. Setting comment to a true value will include comments in the output. AUTHOR
