And for my second post.... I am coming unstuck on Hashes and Arrays. I am using XML:Simple to read in an xml file. In order to read my tree I have to set a flag 'forcearray'. The tree structure is like this: 
 <root>
  <page>
   <field>
     <ID></ID>
     <value></value>
   </field>
  </page>
 </root>

The root can have more many pages, and each page can have many fields. The fields only have the ID and value. I am trying to add a new field to a specific page. So far I have got: 
 my $pageobj=$data->{page}[$pagenumber];
 my $fieldobj=$pageobj->{field};

when dumped this produces: 
[
{ 'value' => [ 'test' ], 'ID' => [ '0000001' ] },
{ 'value' => [ 'test' ], 'ID' => [ '0000002' ] },
{ 'value' => [ 'test' ], 'ID' => [ '0000003' ] },
{ 'value' => [ 'test' ], 'ID' => [ '0000004' ] }
]

I have tried various ways of adding a new field to this, I would ideally like to build a new field from values I enter, and then add it to the array. I tried creating a new hash, and adding in a value and ID. Although I feel I am slipping up somewhere: 
my $pageobj=$data->{page}[$pagenumber];
my $fieldobj=$pageobj->{field};
my %tmpF=();
my @tmpA;
push(@tmpA,"0001");
%tmpF->{ID}=@tmpA;
push(@$fieldobj,%tmpF);

After dumping this, it doesnt seem to have the desired result... Any help would be amazing TienLung
