Java data generator

// create child element
child_NumGp_SNO = doc.createElement("SNo");
child_NumGp.appendChild(child_NumGp_SNO);
String sno = String.valueOf(i+1);
Text txt = doc.createTextNode(sno);
// append child element
child_NumGp_SNO.appendChild(txt);

randint = r.nextInt(101);
System.out.print(randint + "\n");

child_NumGp_RAND = doc.createElement("Rand");
child_NumGp.appendChild(child_NumGp_RAND);
String randomint = String.valueOf(randint);
Text txt2 = doc.createTextNode(randomint);
child_NumGp_RAND.appendChild(txt2);


Above is part of Java code that will generate an output XML file that wil be feed by Serial Comm or Network Port to my earlier Line Graph program.
