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!

xml::handler::canonxmlwriter
XML::Handler::CanonXMLWriter(3) User Contributed Perl Documentation XML::Handler::CanonXMLWriter(3)
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.
