[Expat-discuss] DTD processing

[Ferenc Gémesi]

Dear Gurus,
I am parsing 'xml' file vith 'XML::Perser::Expat' Perl modul. In the 'xml'
file is 'external 'DTD' file reference. 
In the 'DTD' file:

<!ATTLIST catalogue
  maintainer CDATA #REQUIRED
  datestamp  CDATA #REQUIRED
  license    CDATA #REQUIRED>

In the 'xml' file:

<catalogue 
           FALSEmaintainer="Graham.Williams@cmis.csiro.au"
           FALSEdatestamp="1999/05/13"
           FALSElicense="doc.date">

How can I catch the errors in the 'Expat' environment?
Thank You for help,
gferi
