Ok fair enough. How do you access the elements in the sequence? ie. extract
their names?
I just tried your test case as a java class:
package schemaparser;
import java.io.InputStream;
import javax.xml.transform.stream.StreamSource;
import org.apache.ws.commons.schema.XmlSchema;
import org.apache.ws.commons.schema.XmlSchemaCollection;
import org.apache.ws.commons.schema.XmlSchemaObjectTable;
public class XSDSchemaTest2 {
public static void main(String [] args){
try{
InputStream is =
XSDSchemaTest2.class.
getClassLoader().getResourceAsStream("C:\\Users\\Patrick\\Documents\\college\\FYP\\xml\\note.xsd");
XmlSchemaCollection schemaCol = new XmlSchemaCollection();
XmlSchema schema = schemaCol.read(new StreamSource(is),
null);
XmlSchemaObjectTable objectTable = schema.getElements();
System.out.println(objectTable.getCount());
} catch(Exception ex){
ex.printStackTrace();
}
}
}
When I try and run that I get the following error:
org.apache.ws.commons.schema.XmlSchemaException
at
org.apache.ws.commons.schema.XmlSchemaCollection.read(XmlSchemaCollection.java:386)
at
org.apache.ws.commons.schema.XmlSchemaCollection.read(XmlSchemaCollection.java:422)
at
org.apache.ws.commons.schema.XmlSchemaCollection.read(XmlSchemaCollection.java:448)
at schemaparser.XSDSchemaTest2.main(XSDSchemaTest2.java:23)
Any idea what's wrong there?
Thanks,
Patrick
