Top Most Creating XML With is Easy And Very Fast With XOM API

Lets Look in this API.
Steps:
1) First create a Java Project and include the Jar xom-1.2.8.jar in class path.
2)Create two Java Src file as below. API Used in RED Line.

First Java source in:com.myapp



package com.myapp;
import java.math.BigInteger;
import java.util.ArrayList;
import java.util.List;
import nu.xom.Attribute;
import nu.xom.Document;
import nu.xom.Element;


public class HelloWorldXomXmlTest {

List<PcFxStComPartNumberInfo> gridData;

public List<PcFxStComPartNumberInfo> getGridData() {
return gridData;
}

public void setGridData(List<PcFxStComPartNumberInfo> gridData) {
this.gridData = gridData;
}

public static void main(String[] args) {
PcFxStComPartNumberInfo info=new PcFxStComPartNumberInfo();
info.setDescription("my description");
info.setPartCode("0111");
info.setPartNum("TIPS");
info.setStatus("Alive");

PcFxStComPartNumberInfo info2=new PcFxStComPartNumberInfo();
info2.setDescription("my description2");
info2.setPartCode("0122");
info2.setPartNum("MEMS");
info2.setStatus("DEAD");

List<PcFxStComPartNumberInfo> list=new ArrayList<PcFxStComPartNumberInfo>();
list.add(info);

list.add(info2);


HelloWorldXomXmlTest test=new HelloWorldXomXmlTest();
test.setGridData(list);
System.out.println(test.getXMLForPartNumber("hello"));
}

public String getXMLForPartNumber(String userSearchedKeyword){
int totalRecord=this.gridData.size();
Element root = new Element("search_result"); 
Attribute searchKeyword = new Attribute("searchkeyword", userSearchedKeyword);
Attribute records = new Attribute("records", String.valueOf(totalRecord));
root.addAttribute(searchKeyword);
root.addAttribute(records);

Element part_numbers = new Element("part_numbers");
for (PcFxStComPartNumberInfo info : this.gridData) {

String partNumberValue = info.getPartNum();
Element part_number = new Element("part_number");
   Attribute name_attribute = new Attribute("name", partNumberValue);
   part_number.addAttribute(name_attribute);
 
   Element description = new Element("description");
   String descriptionValue = info.getDescription();
   description.appendChild(descriptionValue);
   part_number.appendChild(description);
   part_numbers.appendChild(part_number);

}
   root.appendChild(part_numbers);
   Document doc = new Document(root);
   String result = doc.toXML();
   return result;


}

}

Second Java source in: com.myapp packge. You can remove comparable if you want.


package com.myapp;



import java.util.*;

public class PcFxStComPartNumberInfo  implements Comparable<PcFxStComPartNumberInfo>{

private String partNum;
private String partCode;
//private String subClassId;
//private String subClassName;
private String description;
private String status;
//private List<PcFxStComOrderablePartNumber> opnList;


public String getPartNum() {
return partNum;
}
public void setPartNum(String partNum) {
this.partNum = partNum;
}
public String getPartCode() {
return partCode;
}
public void setPartCode(String partCode) {
this.partCode = partCode;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}

public int compareTo(PcFxStComPartNumberInfo o) {
// TODO Auto-generated method stub
if( o==null)
return 1;
else
return this.getPartNum().compareTo(o.getPartNum());


}
}

Step3) Run your first Java Source a Java Application and see the result. Its better than DOM, SAX and StAX API.
