I convert an old html file to us CSS, so I need to remove various strings and replace them with <span class = "title"> and other tag. I can open and process my file, even change replace the starting tags but not tags that begin at position x and end at position y. Below is an example of the text any help would be appreciated.

<p><a href="http://www.mysite.com"><img src="test.gif" ></a><font size="3" face="Arial"> <u><b>Title</b></u> - Text ............................................................................... ............................... ...................................... .....................</font></p>
<p><a href="http://www.mysite.com"><img src="test.gif" ></a><font size="3" face="Arial"> <u><b>Title</b></u> - Text ............................................................................... ............................... ...................................... .....................</font></p>


import java.io.*;
import java.lang.String.*;

public class FileTestReplace{

public static void main(String args[]){
int count = 0, ch;
try{

File f1 = new File("C:/temp/test.HTML");
BufferedReader in = new BufferedReader(new FileReader(f1));
File f2 = new File("C:/temp/JOUT.HTML");
BufferedWriter out = new BufferedWriter(new FileWriter(f2));
String s="";
int lineCount=0;

String s1 = "<p";
String s2 = "RC";

String searchQuery1 = "search"; // 0
String replaceWord = "<span class = \"title\" >";
String searchQuery2 = "b>";


while ((s=in.readLine())!=null){

if (s.length() > 1){

// Need to trim to get rid of extra space
//Want to only change lines that start as paragraphs
if ( s.substring(0,2).trim().equals(s1) ) {

int startIndexVal = 0;
int endIndexVal = 0;
int endofIndexVal = 0;

// look for the starting index of searchQuery
startIndexVal = 0; //str.indexOf(searchQuery);
endofIndexVal = s.indexOf(s);

// evaluate the ending Index of searchQuery
endIndexVal = startIndexVal + endofIndexVal ;

// Form the string again using the substring() method
s = "<p>" + replace(s, 50, endIndexVal);

out.write(s);
out.newLine();

}
}
in.close();
out.close();
}


catch(IOException e){
System.out.println("I/O Error occurred");
}
}
}

I'd try replaceAll method from String class. Here you have an example
