I wrote a small tool,html parser.I spent serveral hours in coding ,so it must be clumsy.I hope for more advice. the tool is programmed by java and could be used in NT(jdk1.2)   the tool include: in the directory:".\\check\\" 1.config file "tag.des" describe the pare of tag(must be pares ,such as<style></style&gt

2. 3 java classes: (1)position.java

x,y axial, means row and column number,but I have not used the column position) package check; public class position {   public int row=0;   public int column=0;   public position(int r,int c) {     row=r;     column=c;   } } (2)tag.java

record the position) package check; public class tag {   private int pushed=0;   private int poped=0;   private position posPush=null;   private position posPop=null;   private String tagName="";   public tag(String tag) {     tagName=tag;   }   public String getTag() {     return  tagName;   }   public int getPushed() {     return  pushed;   }   public int getPophed() {     return  poped;   }   public int getCountd() {     return  (pushed-poped);   }   public position getPushPos() {     return  posPush;   }   public position getPopPos() {     return  posPop;   }   public void push(position p) {       pushed++;       posPush=p;   }   public void pop(position p) {       poped++;       posPop=p;   }   public boolean isHead(String stoken) {     stoken=stoken.toLowerCase();     if((stoken.startsWith("<"+tagName)==true)&&(stoken.endsWith(">&quot

==true)){       return true;     }     else       return false;   }   public boolean isTail(String stoken) {     if((stoken.startsWith("</&quot

==true)&&(stoken.endsWith(">&quot

==true)&&(stoken.toLowerCase().indexOf(tagName)>0)){       return true;     }     else       return false;   } } (3)html.java(has 3 steps:       a).use paseFile() to read in the file to be checked)       b).use writeFile() to write out the file being arranged "out.html"       c).use check() to check the "out.html" and tell the position error occurs package check; import java.awt.*; import java.io.*; import java.util.*; public class html extends Vector{   private Vector htmlTag=null;   private Stack stack=null;   private String string="",headStr="",tailStr="",between="";   private int tab=0,lastTab=0;   public html() {     String file=".\\check\\tag.des";     try{       String[] tempStr=new String[100];       int count=0;       BufferedReader in=new BufferedReader(new FileReader(file));       String line="";       while((line=in.readLine())!=null){         line=line.substring(0,line.indexOf(";&quot

;      test.writeFile();      test.check();   } } defects: 1.I dont kwon how to select a file to be input and output by java 2.this procedure must fisrt arrange the input file then check the arranged file 3.the code is not elegant, it contains lot of garbage but the idea follows what I paste on the forum serveral days ago.

I've forgot to give the format of "tag.des": eg: html; head; body; tr; td; table; script; select; a;
