How to ignore comments in regular expression???

[katy28]

Hi,

Im creating program that reads a file content and search for a URL. While searching i do not want to take url's present inside the comment(wanna regex to ignore comment(//)).For that

i have written source code but its not working out..Can anyone check and help me out..

This is my source code:

import java.io.*;
import java.util.regex.*;
import java.util.*;
public class sam
{


public static void main(String args[]) throws IOException
{
String wordd;
String word;
String path="(ftp|http|file|gopher|telnet|news)//){1}([^/]+)(/.*)?(/.*)";
Pattern p=Pattern.compile(path,Pattern.COMMENTS);
LineNumberReader fr=new LineNumberReader(new FileReader("javatest.java"));
while((wordd=fr.readLine())!=null)
{
Matcher m=p.matcher(wordd);
while(m.find())
{
word=m.group();
System.out.println("Line"+fr.getLineNumber()+":"+"\t"+wordd);
}
}
}
}

This is the file im trying to get URL:

JavaTest.java:

cdhchukhjkcdhncks
//htrhhhth"D:\maintest\test"
sdgudhudhu
//htrhrthrhht"c:\"
dhdijijdeil
ijidjsa
"a:\maintest"
"A:\test"
"t:"
"t:
/*
"a:\maintest"
"A:\test"
"a:\maintest"
"A:\test"
"a:\maintest"
"A:\test"
*/hisfdsfffd
htrhrthrhht"c:\"
"D:\maintest\test"
/*


When i run the above program output is like this:

C:\jdk1.5.0_08\bin>javac sam.java

C:\jdk1.5.0_08\bin>java sam
