I am able to retrive only one row in this format from data.html file
<trvalign=middlebordercolor=#ffffff><tdwidth='40'CLASS='tdbgpricespagecolorgrey'><fontface='Arial,Helvetica,sans-serif'size='2'>SB</font></td><t
dwidth="23"Class=tdbgpricespagecolorgrey><fontface='Arial,Helvetica,sansserif'size='2'>USAirways</font></td><tdwidth="34"Class=tdbgpricespagecolorgrey><fontface='Arial,Helvetica,sans-serif'size='2'>MIA</font></td><tdwidth="31"Class=tdbgpri
cespagecolorgrey><fontface='Arial,Helvetica,sans-erif'size='2'>LGW</font></td><tdwidth="23"Class=tdbgpricespagecolorgrey><fontface='Arial,Helvetica,sans-serif'size='2'>USAirways</font></td><tdwidth="34"Class=tdbgpricespagecolorgrey><fontface='Arial,Helvetica,sans-serif'size='2'>LGW</font></td>
But i need the output in this format
<fontface='Arial,Helvetica,sans-serif'size='2'>SB     <fontface='Arial,Helvetica,sans-serif'size='2'>USAirways     <fontface='Arial,Helvetica,sans-serif'size='2'>MIA     <fontface='Arial,Helvetica,sans-serif'size='2'>LGW     <fontface='Arial,Helvetica,sans-serif'size='2'>USAirways     <fontface='Arial,Helvetica,sans-serif'size='2'>LGW     <fontface='Arial,Helvetica,sans-serif'size='2'>MIA          <br>
<fontface='Arial,Helvetica,sans-serif'size='2'>CS     <fontface='Arial,Helvetica,sans-serif'size='2'>USAirways     <fontface='Arial,Helvetica,sans-serif'size='2'>MIA     <fontface='Arial,Helvetica,sans-serif'size='2'>LON     <fontface='Arial,Helvetica,sans-serif'size='2'>USAirways     <fontface='Arial,Helvetica,sans-serif'size='2'>LON     <fontface='Arial,Helvetica,sans-serif'size='2'>MIA          <br>
How can i rewrite the code to achive this.
Here is my java code
import java.io.*;
import java.util.*;
import java.util.regex.*;
public class parseHTML {
public static void main(String[] args)
try
BufferedReader in = new BufferedReader(new FileReader("C:\\data.html"));
PrintWriter out = new PrintWriter(new FileWriter("C:\\data1.html"));
String aLine = null;
String abc=null;
String pattern1 ="<tr.+?><td.+?>(.+?)</.+?td><td.+?>(.+?)</.+?td><td.+?>(.+?)</.+?td><td.+?>(.+?)</.+?td><td.+?>(.+?)</.+?td><td.+?>(.+?)</.+?td><td.+?>(.+?)</.+?td><td.+?>(.+?)</.+?td><td.+?>(.+?)</.+?td><td.+?>(.+?)</.+?td><td.+?>(.+?)</.+?td>++";
Pattern p1 = Pattern.compile(pattern1);
while((aLine = in.readLine()) != null)
abc=aLine.replaceAll("(\n|\t|\r)","").replaceAll(" ","");
Matcher m1 = p1.matcher(abc);
if(m1.find())
System.out.println("the value is...."+m1.group());
out.print(m1.group());
m1.reset(aLine);
in.close();
out.close();
catch(IOException exception)
exception.printStackTrace();
Thanks
