Hi Monks,


i have a unique requirement for calculating checksum on a XML file as below

* Read the whole XML file
* Strip of all XML tags
* Bring all XML data into one line
* Will call CRC32 routine to calculate checksum on this one line
to Achieve this iam doing below 

my $tempContent = undef; # Holds final XML data in one line
while (<FILE>){
        my $xml = $_;
        chomp($_);
        while($xml=~m/\<(.+?)\>(.+?)\<\/\1\>/sig){
                my $tag=lc(strip($1));
                ## Below line is the selective condition to ignore all
+ header XML tags and consider only data
                next if ( $tag =~ /TotalAmount|NoOfRecords|TotalBatch|
+CurrentBatch|EODTransactionDate|BankFileSeqNo|TotAmount/i );
                my $attribs="?";
                my $value=strip($2);
                $tempContent .= qq~$value~;
}
$tempContent .= qq~\n~; 
open(OUT,">tmp") or die "Unable to open $! \n";
print OUT $tempContent;
close OUT;
CRC32 ( tmp) ;  # this one can be ignored , i have no problem here
#Showing on trasaction, but in daily there are plenty

# Will calculate checksum for above one line

my problem is, is there any better way to do above ? also , when XML file contains around 10,000 or more trasactions, its taking more time since iam processing line by line and appending in temp variable. pls let me know if i can improve in any of the above areas
