Sax Parser - how to add new nested elements

[alexandra12]

Hello,

I am quite new to Java and Sax Parser. I have spent the last couple of days trying to figure this out.

I have an xml file - - part sample below. I am using Sax Parser to parse the file. I am now trying to add new elements to the xml file along with associated data. I am confused as to how to add the elements.

<?xml version="1.0" encoding="UTF-8"?>
<defaultChartMeasure refDataItem="Speed">
	<chartLabel>
		<chartContents>
			<chartTextItem>
				<dataSource>
					<staticValue>Speed</staticValue>
				</dataSource>
					<conditionalDataSources refVariable="Report Language">
						<conditionalDataSource refVariableValue="en">
							<staticValue>Speed</staticValue>
						</conditionalDataSource>
							<conditionalDataSource refVariableValue="pt-br">
								<staticValue>Velocidade</staticValue>
							</conditionalDataSource>
					</conditionalDataSources>
			</chartTextItem>
		</chartContents>
	</chartLabel>
</defaultChartMeasure>

I want to add elements like the below but with different values

<conditionalDataSource refVariableValue="pt-br">
								<staticValue>Velocidade</staticValue>
							</conditionalDataSource>

Here is my main class file

	//below is all the event handlers that should be in their own class files
		public void printData(){
			
			System.out.println("report size is " + reportl.size());
			for (report tmpR : reportl){
				System.out.println(tmpR.toString());
			}
		}
	
	
//event handler
	@Override
	public void startElement(String s,String s1, String elementName, Attributes attributes)throws SAXException{
		int length = attributes.getLength();

		
		if(elementName.equalsIgnoreCase("conditionalDataSource")){
			inConditionalDataSource=true;
			//set the tempval to null so that their is no previous data in the variable
			String tempValue ="";
//			 print out the attributes of the the element "conditionalDataSource"
			for (int i=0; i<length; i++) {
	            // Get names and values for each attribute
	            String name = attributes.getQName(i);
	            String value = attributes.getValue(i);
	   //         System.out.println("elementName= " +name);    
	            System.out.println("elementValue= " + value);
			}
			//create a new instance of conditionalDataSource
			conditionalDataSource = new defaultChartMeasure();
		//	tempValue.setType(attributes.getValue("type"));
		}
		
				
		
	}
	@Override
	public void endElement(String s, String s1,String elementName)throws SAXException{
	
		//end element always goes to the end of the document REGARDLESS
		if(elementName.equalsIgnoreCase("ConditionalDataSource")){
			//adding it to the list
	//		myempls.add(tempemp);
			
			
			inConditionalDataSource = false;
		
		}	
		
		//now we have to loop through the rest of the nodes in the element
		else if(elementName.equalsIgnoreCase("staticValue")){
	//		tmpValue.setStaticValue(tmpValue);
		}
	
	}
	
	@Override
	public void characters(char ch[],int start, int length) throws SAXException{
		
		tmpValue = new String(ch,start,length);
	
		}

Here is the class file for adding the elements but it is not complete

public class defaultChartMeasure {
	private String refDataItem;
	private String staticValue;
	private String refVariable;

	//creating the constructor
	public defaultChartMeasure(){
		setRefDataItem(null);
		setRefVariable(null);
		setStaticValue(null);
	}
	
//use void for set ONLY and string etc for get
	
	public void setRefDataItem(String refDataItem){

		this.refDataItem =refDataItem;
	}
	
	public void setRefVariable(String refVariable){
		this.refVariable = refVariable;
		
	}
	
	public void setStaticValue(String staticValue){
		this.staticValue = "<staticValue></staticValue>";
		
		
	}
}

Can someone explain to me what I need to do ?
Any advice will be greatly appreciated !

I am no expert in this -- not by any means, but I always thought that a SAX parser was for, well, parsing, and that it is not a tool that is used for writing to an XML file.

Edit: Google showed me this: generating-xml-using-sax-and-java.

It states that a SAX parser is not used for generating XML, but a SAX "framework" can be used for this purpose. Though I must post the caveat that this is nothing I've ever worked with.
