[jdom-interest] percent signs and XML parsing when internal DTD entities declared

[Ted Toth]

I've slightly altered the inline.xml file adding a link from the catalog.xml file which contains "%". This causes an exception that doesn't make any sense to me. I'm not sure this is a JDOM issue since the original exception is a SAXParseException. I think it has something to do with the internal DTD declaration. Any ideas?

------- altered inline.xml ----------------------------------------------------------

<?xml version='1.0'?>

<!DOCTYPE DOCUMENT [
  <!ELEMENT DOCUMENT (#PCDATA)>
  <!ENTITY nbsp '&#160;'>
  <!ENTITY aring '&#229;'>
  <!ENTITY auml '&#228;'>
  <!ENTITY ouml '&#246;'>
  <!ENTITY Aring '&#197;'>
  <!ENTITY Auml '&#196;'>
  <!ENTITY Ouml '&#214;'>
]>
