Ok, I create an entity resolver to specify the external DTD. However, I'm
getting many parse errors of the kind
Error: Parsing - Element type "task-description" must not be declared more
than once.
Error: Parsing - Element type "cmr-type" must not be declared more than
once.
Error: Parsing - Element type "related-mrbs" must not be declared more than
once.
Error: Parsing - Element type "related-mrb" must not be declared more than
once.
Error: Parsing - Element type "task-cat" must not be declared more than
once.
Error: Parsing - Element type "cmr-intervals" must not be declared more than
once.
Error: Parsing - Element type "cmr-interval" must not be declared more than
once.
Error: Parsing - Element type "precluded-tasks" must not be declared more
than once.
Error: Parsing - Element type "precluded-task" must not be declared more
than once.
Error: Parsing - Element type "precluded-struct-task" must not be declared
more than once.
Error: Parsing - Element type "precluded-struct-tasks" must not be declared
more than once.
Error: Parsing - Element type "precluded-sys-task" must not be declared more
than once.
This is odd because I placed the same DTD in the XML file's DOCTYPE
declaration and parse the file w/o using an entity resolver and it parses
without errors. What am I doing wrong with my entity resovler or is it not
setting a specific DTD feature on the Parser?
snippet - code of entity resolver
==============================================
public InputSource resolveEntity(String publicId, String systemId)
throws SAXException, IOException
{
if(_MyOwnSystemId != null)
{
InputSource is = new InputSource(_MyOwnSystemId );
return is;
}
else// use the default behavior
{
return null;
}
}
========================================================================
