Hi Monk

sub DeleteValueTreeWithinHash
{
   my $HashData      = $_[0];
   my $FindValue     = $_[1];

   my $value   = &RecursiveFunctionToDeleteValueWithinHash($HashData, 
+$FindValue);
   
   print Dumper ($value);
   
   %{$HashData} = undef;      
   %{$HashData} = %{$value};

   print Dumper ($HashData);
}

I have this function which is called by &DeleteValueTreeWithinHash(\%HashData, "index"); when I do a dumper on $value, i see all this data to screen. when I do a dumper on $HashData, i see no values.

$VAR1 = {
          '' => undef
        };

Any ideas on what i'm doing wrong? All I wanted to do was create a recursive function and delete a branch or element if it finds the text there. Update: Maybe I didn't put enough details so here is everything. This below is how %HashData looks like before this function line &DeleteValueTreeWithinHash(\%HashData, "index");

This is my recursive function to remove the element. Note my hash structure above is multi dimensional such that it has no limit to it's depth.

sub RecursiveFunctionToDeleteValueWithinHash
{
   my $HashData                  = $_[0];
   my $FindValue                 = $_[1];
   my $keys;

   foreach $keys (sort { $a <=> $b } keys %{$HashData})
   {
      if ($keys =~ m/^(([\d]+)\.([\d]+) )/)
      {
         my $MarkerNumber  = $1;
         my $line_data     = $keys;
         $line_data =~ s/^([\d]+)\.([\d]+) //;
       
         if ($line_data =~ m/$FindValue/)
         {
            delete $$HashData{$keys};
            next ;
         }
         my @values = (sort { $a <=> $b } keys %{$$HashData{$keys}});
         if (scalar(@values) != 0)
         {
            $$HashData{$keys} = &RecursiveFunctionToDeleteValueWithinH
+ash($$HashData{$keys}, $FindValue);
         } 
      }
   }
   return $HashData;

This is the value of print Dumper ($value); I just want to set this as my main hash. Notice that any values with the word index is removed from the hash?
