Xml Schema parser

Hello,
Given the following line of code;
SchemaParser sparser = new SchemaParser(schemaParserFile.toURI().toURL());
The URL points to an xml file.

How could one print/show the content of sparser?  
I have tried; System.out.print(sparser.getConstraints()); but nothing get printed. it could be that it is empty.
Also, if the xml file does not have "constraints" then the method getContraints might have nothing to get.
I was hoping it would read/get the tags, but it does not seem like it does.
Any suggestions?

From what I can gather on this API, you don't call the SchemaParser directly (at least doesn't seem like it to me).  You pass the SchemaUrl to the factory method that creates the instance of Validator.  The Validator object then uses the Constraints passed back by the parser to determine if data you pass it to validate meets the constraints imposed by the XSD (Schema Document).

If you are using SchemaParser from this package:
http://oodt.jpl.nasa.gov/metadata-service/apidocs/jpl/eda/metadata/validation/package-summary.html

Then it appears you get the constraints that the Schema defines as a Map.  The API for the Constraint object itself can be found on same link above.

Otherwise, please provide the package you are using SchemaParser from.

mwvisa1, while I got the code from here; http://www.javaworld.com/jw-11-2000/Validation/src.zip 
I have debugged it some.  If you need to see the debugged version, please let me know.

mwvisa1, I looked at the link that you provided and it is the package I am using.  How then could I look at the Map?  The xml file I am working with does not provide constraints.  It provides tags and it is these tags information that I am hoping to parse.
