推荐答案
这同样的事情我解析。做
That same thing i done with parsing.
XML处理程序类 -
class xmlHandler extends DefaultHandler {
private Vector nodes = new Vector();
private Stack tagStack = new Stack();
public void startDocument() throws SAXException {
}
public void startElement(String uri, String localName, String qName,
Attributes attributes) throws SAXException {
// System.out.println("1");
if (qName.equals("clause")) {
Noden node = new Noden();
nodes.addElement(node);
// System.out.println("2");
}
// System.out.println("3");
tagStack.push(qName);
}
public void characters(char[] ch, int start, int length)
throws SAXException {
String chars = new String(ch, start, length).trim();
if (chars.length() > 0) {
String qName = (String) tagStack.peek();
Noden currentnode = (Noden) nodes.lastElement();
// System.out.println(qName);
if (qName.equals("en")) {
currentnode.setEn(chars);
} else if (qName.equals("alt")) {
currentnode.setAlt(chars);
}
}
}
public void endElement(String uri, String localName, String qName,
Attributes attributes) throws SAXException {
tagStack.pop();
}
public void endDocument() throws SAXException {
StringBuffer result = new StringBuffer();
for (int i = 0; i < nodes.size(); i++) {
Noden currentnode = (Noden) nodes.elementAt(i);
result.append("En : " + currentnode.getEn() + " Alt : "
+ currentnode.getAlt() + "\n");
}
System.out.println(result.toString());
}
class Noden {
private String en;
private String alt;
public Noden() {
}
public void setEn(String en) {
this.en = en;
}
public void setAlt(String alt) {
this.alt = alt;
}
public String getEn() {
return en;
}
public String getAlt() {
return alt;
}
};
retriving -
try
{
SAXParserFactory factory = SAXParserFactory.newInstance();
SAXParser saxParser = factory.newSAXParser();
InputStream is = null;
String xml = "your pasable string";
String newXml = xml.substring(xml.indexOf("<translation>"), xml.indexOf("]]"));
System.out.println(newXml);
is = new ByteArrayInputStream(newXml.getBytes());
InputSource inputSource = new InputSource(is);
saxParser.parse(inputSource,new xmlHandler());
}
catch(Exception ex) {
ex.printStackTrace();
}
这将帮助您。
