Unable to transform XML with XSL in java code

Question

Hi,
Could somebody please tell me what's wrong with my code, why it isn't transform the XML with XSL to the output that I want. If I use the command line to transform the XML, it output perfectly:
java org.apache.xalan.xslt.Process -in marc.xml -xsl MARC21slim2MODS.xsl -out out.xml
Here is the code of my program to transform the XML with XSL, I am using xalan-j_2_2-bin:
import java.io.*;
import java.net.*;
import java.util.*;
import org.w3c.dom.*;
import javax.xml.parsers.*;
import javax.xml.transform.*;
import javax.xml.transform.stream.*;
import javax.xml.transform.dom.*;
import java.math.BigInteger;
String xslDoc = "MODS.xsl";
String xmlResult = "out.xml";
DocumentBuilderFactory dfactory = DocumentBuilderFactory.newInstance();
dfactory.setNamespaceAware(true);
DocumentBuilder docBuilder = dfactory.newDocumentBuilder();
Document xmlDoc = docBuilder.newDocument();
Element root = xmlDoc.createElement("collection");
root.setAttribute("xmlns", "http://www.loc.gov/MARC21/slim");
xmlDoc.appendChild(root);
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer(new StreamSource(xslDoc));
FileWriter fw = new FileWriter(new File(xmlResult));
StreamResult output = new StreamResult(fw);
transformer.transform(new DOMSource(xmlDoc), output);
fw.flush();
fw.close();

Answer 1

I am using the same XSL file. My Java program use the same XSL file I used in the command line.
It is possible that my Java code is using a different parser, but I developed a seperate program to parse the XML using the same parser that my Java code is using. It output the result I expected. Here is the code for the program:
import java.io.*;
import javax.xml.transform.*;
import javax.xml.transform.stream.*;
public class Convertor {
public static void main(String[] args) throws Exception {
String xslDoc = "MARC21slim2MODS.xsl";
String xmlResult = "out.xml";
String xmlDoc = marc.xml";
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer(new StreamSource(xslDoc));
StreamSource xmlSource = new StreamSource(xmlDoc);
FileWriter fw = new FileWriter(new File(xmlResult));
StreamResult output = new StreamResult(fw);
transformer.transform(xmlSource, output);
}
