I need to extract XML file embedded in PDF. I looked into module 'CAM::PDF' by Chris Dolan, but I could not find suitable examples. I need to do the extraction as part of a larger Perl program, without calls to third party tools like 'pdfdetach' or 'pdftk'. I would much appreciate any suggestion that could help me to achieve this task. Below is fragment of dictionary, returned by method 'getRootDict()'; you can see the name of XML file referenced there: 
$VAR1 = {
          'Type' => bless( {
                             'gennum' => 0,
                             'value' => 'Catalog',
                             'type' => 'label',
                             'objnum' => 83
                           }, 'CAM::PDF::Node' ),
          'Names' => bless( {
                              'gennum' => 0,
                              'value' => {
                                           'EmbeddedFiles' => bless( {
                                                                      
+ 'gennum' => 0,
                                                                      
+ 'value' => {
