Unable to read special characters from xml using java
When i try to read the xml from java using SAX parser, it is unable to read the content in element present after special character
For ex:
<title>It's too difficult</title>
After reading using the SAX parser, it's displaying only It
How to handle special characters. My sample code is as below
package com.test.java;
import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;
import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;
public class ReadXMLUsingSAXParser {
public static void main(String argv[])开发者_Go百科 {
try {
SAXParserFactory factory = SAXParserFactory.newInstance();
SAXParser saxParser = factory.newSAXParser();
DefaultHandler handler = new DefaultHandler() {
int titleCount;
boolean title = false;
boolean description = false;
public void startElement(String uri, String localName,
String qName, Attributes attributes)
throws SAXException {
// System.out.println("Start Element :" + qName);
if (qName.equalsIgnoreCase("title")) {
title = true;
titleCount+=1;
}
if (qName.equalsIgnoreCase("description")) {
description = true;
}
}
public void endElement(String uri, String localName,
String qName)
throws SAXException {
// System.out.println("End Element :" + qName);
}
public void characters(char ch[], int start, int length)
throws SAXException {
if (title&&titleCount>2) {
System.out.println("title : "
+ new String(ch, start, length)+":"+titleCount);
title = false;
}
if (description) {
System.out.println("description : "
+ new String(ch, start, length));
description = false;
}
}
};
saxParser.parse("C:\\Documents and Settings\\sukumar\\Desktop\\sample.xml", handler);
} catch (Exception e) {
e.printStackTrace();
}
}
}
The characters(char ch[], int start, int length)
methode does not read full lines, you should store the characters in a StringBuffer
and use it in the endElemen
method.
E.g.:
private StringBuffer buffer = new StringBuffer();
public void endElement(String uri, String localName,
String qName)
throws SAXException {
if (qName.equalsIgnoreCase("title")) {
System.out.println("title: " + buffer);
}else if (qName.equalsIgnoreCase("description")) {
System.out.println("description: " + buffer);
}
buffer = new StringBuffer();
}
public void characters(char ch[], int start, int length)
throws SAXException {
buffer.append(new String(ch, start, length));
}
