using System;
using System.IO;
using Sax.Net;
using Sax.Net.Helpers;
public class MySAXApp : DefaultHandler {
public static void Main(params string[] args) {
var handler = new MySAXApp();
IXmlReader parser = XmlReaderFactory.Current.CreateXmlReader();
parser.ContentHandler = handler;
parser.ErrorHandler = handler;
foreach(string fileName in args) {
using(StreamReader reader = new StreamReader(fileName)) {
parser.Parse(new InputSource(reader));
}
}
}
public override void StartDocument() {
Console.WriteLine("Start document");
}
public override void EndDocument() {
Console.WriteLine("End document");
}
public override void StartElement(string uri, string localName, string qName, IAttributes atts) {
if (string.IsNullOrEmpty(uri)) {
Console.WriteLine("Start element: {0}", qName);
} else {
Console.WriteLine("Start element: {{{0}}}{1}", uri, localName);
}
}
public override void EndElement(string uri, string localName, string qName) {
if (string.IsNullOrEmpty(uri)) {
Console.WriteLine("End element: {0}", qName);
} else {
Console.WriteLine("End element: {{{0}}}{1}", uri, localName);
}
}
public override void Characters(char[] ch, int start, int length) {
Console.Write("Characters: \"");
for (int i = start; i < start + length; i++) {
switch (ch[i]) {
case '\\':
Console.Write("\\\\");
break;
case '"':
Console.Write("\\\"");
break;
case '\n':
Console.Write("\\n");
break;
case '\r':
Console.Write("\\r");
break;
case '\t':
Console.Write("\\t");
break;
default:
Console.Write(ch[i]);
break;

<?xml version="1.0"?>
