Regular Expresson to Extrcat URLs from img src tags

Question

Hi,
I have a huge string containing html tags, some of these tags being <img src="URL"> ones. I need to extract the urls from all the occurences of these tags in the input string. This is what I am doing:
Pattern p=null;
Matcher m= null;
String word0= null;
String word1= null;
p= Pattern.compile(".*<img[^>]*src=\"([^\"]*)",Pattern.CASE_INSENSITIVE);
m= p.matcher(txt);
while (m.find())
    word0=m.group(1);
    System.out.println(word0.toString());
     }The problem with this code is that this prints only the last URL. For example if there are 5 <img src="URL"> tags, this code prints only the URL contained withn the 5th< img src> tag. Please tell me how to solve this.
Thanking you in advance

Here's another approach:
ok so this is assuming that the source text is not one line of strings, but mulitple lines.
String[] lines = txt.split("\n")this splits the string based on the newline character. then you can iterate through the array and use the pattern on each string. The only thing that can go wrong here is if there are two images in one line of code. Then you can use some of the methods in the String class to find each instance of "img src=", and you can figure out the rest.
another, better, way to split the string is with a string tokenizer (simple method in my library):
* Returns an array of strings from splitting the givin string
* with the given deliminator.  See the example<br/>
* <br/>
* <i>Example:</i><br/>
* <code>splitTokens("ID: 1920129 NAME: JOHNY IAMYOURFATHER: IDONOTWANT", ": ")</code> would return:<br/>
* <code>["ID",190129","NAME","JOHNY","IAMYOURFATHER","IDONOTWANT"]</code>
* @param base
*               the string to be split
* @param delim
*               the deliminator that is used to split the string.  If the
*               deliminator is <code>", "</code>, then the string will be
*               split on any combination of commas and spaces, along with
*               individual commas and spaces.
* @return an array of strings split from the base string by the deliminator
public static String[] splitTokens(String base, String delim) {
     StringTokenizer toker = new StringTokenizer(base, delim);
     String pieces[] = new String[toker.countTokens()];
     int index = 0;
     while (toker.hasMoreTokens()) {
          pieces[index++] = toker.nextToken();
     return pieces;
}{code}
