If your input is well-formed XML, it would be better to use XML XPath tools to extract the data.

Install Perl-XML-XPath in your system and you can use the following to do the job. This perl script take input from STDIN
Code:
#!/usr/bin/perl

use XML::XPath;
$xp = XML::XPath->new(ioref => \*STDIN);
$nodeset = $xp->find('//project');
foreach $node ($nodeset->get_nodelist) {
  print $node->getAttribute('name');
  print $node->getAttribute('revision');
}

   Original XML:
       -o, --original=value
	      XML is contained in the named file

       -O, --original-string=value
	      XML is contained in the supplied string

   Operation:
       -n, --new=value
	      Compare the original XML to the contents of the named file

       -N, --new-string=value
	      Compare the original XML to the contents of the supplied string

EXAMPLES

       Obtain the two different configuration files by running cibadmin on the two cluster setups to compare:

	      # cibadmin --query > cib-old.xml

	      # cibadmin --query > cib-new.xml

       Calculate and save the difference between the two files:

	      # crm_diff --original cib-old.xml --new cib-new.xml > patch.xml

       Apply the patch to the original file:

	      # crm_diff --original cib-old.xml --patch patch.xml > updated.xml
