Ok that works now and it prints 1 for the answer which is correct. Finally!
The different with my other program is I have the following class:
package schemaparser;
import java.io.*;
import javax.xml.transform.stream.StreamSource;
import org.apache.ws.commons.schema.*;
public class XSDParser {
private InputStream is;
private XmlSchemaCollection schemaCol;
private XmlSchema schema;
public XSDParser(String fileName){
try {
is = new FileInputStream(fileName);
schemaCol = new XmlSchemaCollection();
schema = schemaCol.read(new StreamSource(is), null);
} catch (FileNotFoundException ex) {
ex.printStackTrace();
}
}
public void printSchema(){
schema.write(System.out);
}
public int getRootNode(){
//XmlSchemaObjectTable attribsObjTbl = schema.getAttributes();
XmlSchemaObjectTable elementsObjTbl = schema.getElements();
return elementsObjTbl.getCount();
}
}
And the following class:
package schemaparser;
public class XMLSchemaTest {
public static void main(String [] args) {
XSDParser xsdParser = new
XSDParser("C:\\Users\\Patrick\\Documents\\college\\FYP\\xml\\note.xsd");
xsdParser.printSchema();
System.out.println(xsdParser.getRootNode());
}
}
And for some reason here it prints zero!
