Hi richill!

This is what I had in mind. Parse the xml file once building a hash keyed on file name with sub keys giving the before and after links (see the Dump of the hash below).

The File::Find callback sub parses each html file that 'exists' in the lookup and changes the link as appropriate.

The html is written to STDOUT. The file still needs to be written to its final destination.

Hope that helps and good luck :-)

use warnings;

use XML::Simple;
use File::Find;
use HTML::TokeParser::Simple;
use Data::Dumper;

my $dir = "C:/perm/monks/files/html";

my $xmlfile = "C:/perm/monks/xmlfile/urlchange.xml"; 
my %lookup = get_lookup($xmlfile);

find(\&wanted, $dir);

sub wanted {

  my $file = $_;
  return unless -f $file;
    
  my $rel = $File::Find::name;
  $rel =~ s/$dir//;
  return unless exists $lookup{$rel};
  
  my $p = HTML::TokeParser::Simple->new($file)
    or die "couldn't parse $file";
  
  my $new_html;
  while (my $t = $p->get_token){
    if ($t->is_start_tag('a')){
      my $href = $t->get_attr('href');
      if ($lookup{$rel}{from} = $href){
        $t->set_attr('href', $lookup{$rel}{to});
      }
    }
    $new_html .= $t->as_is;
  }
  
  if (1){
    print "$File::Find::name\n";
    print "$new_html\n";
    print '-' x 20, "\n";
  }
  # todo

    my @records = @{$data->{$sheet}};
    for my $record (@records){
      $lookup{$record->{OriginPage}} = {
        from => $record->{LinkToPage},
        to   => $record->{New_location},

I created some dummy html files (using file names and links from the xml file) e.g.: 
<html>
<head>
<title>index.asp</title>
</head>
<body>
<a href="http://quicklinkurl1/index.asp">link</a>
</body>
</html>

[download]
output showing that the links have been changed: 
C:/perm/monks/files/html/meeting/index.asp
<html>
<head>
<title>index.asp</title>
</head>
<body>
<a href="xxxxxxx">link</a>
</body>
</html>
--------------------
C:/perm/monks/files/html/meeting/lunchtime-meeting/index.asp
<html>
<head>
<title>index.asp</title>
</head>
<body>
<a href="another changed url">link</a>
</body>
</html>
--------------------
C:/perm/monks/files/html/meeting/series/index.asp
<html>
<head>
<title>index.asp</title>
</head>
<body>
<a href="new url">link</a>
</body>
</html>

update:
fixed some badly formed html in the dummy files.
update 2:
Note that the last two records in you xml refer to the same page and link but with a different 'new location'. The third record was therefore ignored.
