hi jason
i've actually been having a look at generating digester rulesets and beans
from xml-schema (along the lines you suggest earlier).
i have an extended set of pattern matching rules (which now work pretty
well against more complex schema) and an ant setup that's working in terms
of using digester to create the initial rules for the schema->bootstrap
object model parsing. i had hoped to be generating basic beans with
digester rulesets this weekend but unfortunately i got tied up with an
upgrade that went bad :(
i'm going to need some test schema to run against so maybe i'll have a go
at generating the ones you need. even if i finish second, it'd be
interested to compare notes :)
i'm not really up to speed on gump. are the schema are the ones in
jakarta-alexandria/src/xml ?
BTW i've found that creating a rule implementation that just prints out
debugging information is really useful for debugging pattern matching
rulesets - something like
class TestRule extends Rule
{
protected String msg;
TestRule(Digester digester,String msg)
{
super(digester);
this.msg=msg;
System.out.println(msg + " CREATED");
}
public void begin(org.xml.sax.Attributes attributes)
{
System.out.println(msg + " BEGIN");
}
public void body(java.lang.String text)
{
System.out.println(msg + " BODY " + text);
}
public void end()
{
System.out.println(msg + " END");
}
public void finish()
{
System.out.println(msg + " FINISH");
}
}
