userid='F100206' situation='active' discoveredSituation='CONFIRMED' accountExists='true'>
<MemberObjectGroups>
<ObjectRef type='ObjectGroup' id='#ID#Top' name='Top'/>
</MemberObjectGroups>
</Account>


open FH,"<a.txt";
my @arr=<FH>;
close FH;
foreach(@arr){
while(m/ (.*?=".*?")/){
my $str=$1;
$_=$';
$hash{$1}=$2 if ($str=~m/(.*)="(.*)"/);
}
print $hash{accountId},"|",$hash{createDate},"|",$hash{userid},"|",$hash{creator},"|",$hash{accountExists} ,"|",$hash{resource},"|",$hash{lastModifier},"\n";

   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

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
