Perl/Shell Script to edit XML Files

Hi Experts,
 I would appreciate some perl/shell scripts which I can use to edit an XML file to insert the data which i have in a flat file.

For ex: Here is a sample XML file

<oim-data resource="Siebel Resource Object">

<attribute name="IT Resource Type">SIEBEL IT Resource </attribute>


<child-record table="UD_SIEBEL_R">

 <attribute name="Responsibility">SNI - Broker</attribute>
</child-record>
</oim-data>
In the above code, i would want to edit the tag

<attribute name="Responsibility">SNI - Broker</attribute>

and generate multiple XML Files with the data i have from the flat file, the sample flat file as follows

Flat File:
SNI - Inside Sales Leader/Exec
SNI - Collections Agent/Credit Tech
SNI - Data Steward/Info Admin
SNI - Campaign Administrator
SNI - Sales Team Administrator
SNI - Inside Sales User

and would want to name the resulting XML file to as SNI - Inside Sales Leader/Exec.xml and the output XML should look like

<oim-data resource="Siebel Resource Object">

<attribute name="IT Resource Type">SIEBEL IT Resource </attribute>


<child-record table="UD_SIEBEL_R">

 <attribute name="Responsibility">SNI - Inside Sales Leader/Exec</attribute>
</child-record>
</oim-data>


Thanks in advance

Note that there are some characters in your new names that cannot be used in a filename, such as /.  And, although allowed, spaces are not usually wanted in a filename.  Here is a script that does what you want, replacing the invalid characters with _ in the filename.
#!/usr/bin/perl
use strict;
use warnings;
 
#NOTE: replace flat.txt with the name of your flat file
open(my $in, "<flat.txt") or die "Flat: $!\n";
my @flat = <$in>;
chomp(@flat);
 
local $/;
#NOTE: replace test1.xml with the name of your original xml
open($in, "<test1.xml") or die "xml: $!\n";
my $xml = <$in>;
close($in);
 
foreach (@flat) {
	next unless /\S/;  #Skip blank lines
	my $name=$_;
	$name =~ s/[^\w]/_/g;
	
	my $newxml=$xml;
	$newxml =~ s/(<attribute name="Responsibility">).*(<\/attribute>)/$1$_$2/;
	open(my $out, ">$name.xml") or die "out: $!\n";
	print $out $newxml;
	close($out);
}

Thanks Adam, works like a charm, As far as the file name , even the lines with '/' are getting replaced by an '_', for ex: SNI Broker is getting replaced as SNI___Broker_ , actually i would like to  supply the file names by a different flat file with no '/', can you please make the change for that.

Like I said, spaces are not normally wanted in filenames, so the script removes them.  To allow spaces, change line 19 to this:
    $name =~ s/[^\w ]/_/g;
(notice the added space after w)

If you want to supply filenames:
#NOTE: replace flat.txt with the name of your flat file
open(my $in, "<flat.txt") or die "Flat: $!\n";
my @flat = <$in>;
chomp(@flat);
close($in);
 
#NOTE: replaces names.txt with the name of the file containing filenames
open($in, "<names.txt") or die "Names: $!\n";
my @names=<$in>;
chomp(@names);
close($in);
 
local $/;
#NOTE: replace test1.xml with the name of your original xml
open($in, "<test1.xml") or die "xml: $!\n";
my $xml = <$in>;
close($in);
 
for(my $i=0; $i<=$#flat; $i++) {
    next unless $flat[$i] =~ /\S/;  #Skip blank lines
    
    my $newxml=$xml;
    $newxml =~ s/(<attribute name="Responsibility">).*(<\/attribute>)/$1$_$2/;
    open(my $out, ">$names[$i]") or die "out: $!\n";
    print $out $newxml;
    close($out);
}
