Content of generated XML document to variable - Oracle ...

Question

Hello everybody,
here is sample code which generates XML document:
* This is a sample application program which is built using the
* classes generated by the XML DTD Class Generator. The External DTD
* File "Widl.dtd" or the XML document which "Widl.xml" which is compliant
* to Widl.dtd is used to generate the classes. The application
* SampleMain.java is used to generate the classes which takes the DTD
* or XML document as input parameters to generate classes.
import oracle.xml.classgen.CGNode;
import oracle.xml.classgen.CGDocument;
import oracle.xml.classgen.DTDClassGenerator;
import oracle.xml.classgen.InvalidContentException;
import oracle.xml.parser.v2.DTD;
public class TestWidl
public static void main (String args[])
try
WIDL w1 = new WIDL();
DTD dtd = w1.getDTDNode();
w1.setNAME("WIDL1");
w1.setVERSION(WIDL.VERSION_1_0);
SERVICE s1 = new SERVICE("Service1", "Service_URL");
s1.setINPUT("File");
s1.setOUTPUT("File");
BINDING b1 = new BINDING("Binding1");
b1.setTYPE(BINDING.TYPE_INPUT);
BINDING b2 = new BINDING("Binding2");
b2.setTYPE(BINDING.TYPE_OUTPUT);
VARIABLE v1 = new VARIABLE("Variable1", VARIABLE.NULLOK_FALSE);
v1.setTYPE(VARIABLE.TYPE_STRING);
v1.setUSAGE(VARIABLE.USAGE_INTERNAL);
v1.setVALUE("value");
VARIABLE v2 = new VARIABLE("Variable2", VARIABLE.NULLOK_TRUE);
v2.setTYPE(VARIABLE.TYPE_STRING1);
v2.setUSAGE(VARIABLE.USAGE_HEADER);
VARIABLE v3 = new VARIABLE("Variable3", VARIABLE.NULLOK_FALSE);
v3.setTYPE(VARIABLE.TYPE_STRING2);
v3.setUSAGE(VARIABLE.USAGE_FUNCTION);
v3.setMASK("mask");
CONDITION c1 = new CONDITION("CRef1", "CMatch1");
c1.setSERVICE("Service1");
c1.setTYPE(CONDITION.TYPE_SUCCESS);
CONDITION c2 = new CONDITION("CRef2", "CMatch2");
c2.setTYPE(CONDITION.TYPE_RETRY);
CONDITION c3 = new CONDITION("CRef3", "CMatch3");
c3.setSERVICE("Service3");
c3.setTYPE(CONDITION.TYPE_FAILURE);
REGION r1 = new REGION("Region1", "Start", "End");
b1.addNode(r1);
b1.addNode(v1);
b1.addNode(c1);
b1.addNode(v2);
b2.addNode(c2);
b2.addNode(v3);
w1.addNode(s1);
w1.addNode(b1);
w1.addNode(b2);
w1.validateContent();
w1.print(System.out);
catch (Exception e)
System.out.println(e.toString());
e.printStackTrace();
I see the method w1.print(System.out) which shows content of xml to console. But how can I store xml to some String variable? Thank you in advance.

If there is a version of the "print" method that can write to a Writer, then:StringWriter sw = new StringWriter();
w1.print(sw);
String result = sw.toString();But if you can only write to an OutputStream then:ByteArrayOutputStream baos = new ByteArrayOutputStream();
w1.print(baos);
String result = new String(baos.toByteArray(), encoding);where "encoding" is a string containing the name of the encoding used to write the XML. Possibly you can control that via "w1.setENCODING(something)" or some other way.
