私はDOMパーサ 2）私たちは 1をパーサーに使用してそれを行うことができますすべての詳細 自分たちは（プリント）を析出することができる方法以下の私の質問に答えがわかっ）SAXパーサ
public void ReadAndPrintXMLfileUsingDOM()
{
try {
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
InputStream rStream = null;
try
{
rStream = getClass().getResourceAsStream("sample.xml");;
}catch (Exception e)
{
System.out.println(e.getMessage());
}
Document doc = docBuilder.parse(rStream);
doc.getDocumentElement().normalize();
System.out.println ("Root element of the doc is " +
doc.getDocumentElement().getNodeName());
NodeList listOfPersons = doc.getElementsByTagName("ROW");
int totalPersons = listOfPersons.getLength();
System.out.println("Total no of people : " + totalPersons);
for(int s=0; s<listOfPersons.getLength() ; s++)
{
Node firstPersonNode = listOfPersons.item(s);
Element firstPersonElement = (Element)firstPersonNode;
System.out.println("==============Name value = " + firstPersonElement.getAttribute("Name"));
System.out.println("===============CheckBox value = " + firstPersonElement.getAttribute("CheckBox"));
System.out.println("==============Type value = " + firstPersonElement.getAttribute("Type"));

NodeList firstNameList = firstPersonElement.getElementsByTagName("COL");
int child_lng=firstNameList.getLength();
for(int j=0;j<child_lng;j++)
{
Node innernode=firstNameList.item(j);

NamedNodeMap attributes = innernode.getAttributes();

System.out.println("+++++++++++++++Node Value : " +value.getNodeValue());
}
}
}catch (SAXParseException err)
{
System.out.println ("** Parsing error" + ", line "
+ err.getLineNumber() + ", uri " + err.getSystemId());
System.out.println(" " + err.getMessage());
}catch (SAXException e)
{
Exception x = e.getException();
((x == null) ? e : x).printStackTrace();
}catch (Exception t)
{
System.out.println(t.getMessage());
}
}
第二の方法であります
public void ReadAndWriteXMLFileUsingSAXParser(){
try
{
DefaultHandler handler = new MyHandler();
// parseXmlFile("infilename.xml", handler, true);
SAXParserFactory factory = SAXParserFactory.newInstance();
SAXParser saxParser = factory.newSAXParser();
InputStream rStream = null;
rStream = getClass().getResourceAsStream("sample.xml");
saxParser.parse(rStream, handler);
}catch (Exception e)
{
System.out.println(e.getMessage());
}
}
}
class MyHandler extends DefaultHandler {
String rootname;Attributes atr;
private boolean flag=false;
public void startElement(String namespaceURI, String localName,
String qName, Attributes atts) {
rootname=localName;
atr=atts;
if(rootname.equalsIgnoreCase("ROW")){
flag=true;
int length = atts.getLength();
for (int i=0; i<length; i++) {
String name = atts.getQName(i);
String value = atts.getValue(i);
System.out.println(name+"**********"+value);
}
}
}
public void characters(char[] ch, int start, int length){
String value=new String(ch,start,length);
if(flag)
{
if(rootname.equalsIgnoreCase("COL")){
int length2 = atr.getLength();
for (int i=0; i<length2; i++) {
String name1 = atr.getQName(i);
String value1 = atr.getValue(i);
System.out.println(name1+"**********"+value1);
}
System.out.println("++++++++++++++"+value);
}
}
}
public void endElement(String uri, String localName, String qName){
rootname=localName;
if(rootname.equalsIgnoreCase("ROW")){
flag=false;
}
}
}
