I need to replace a bunch of xml tags with a unique TAG, I found a solution but I am not sure it's the best out there... What would you propose?

/** Group tags replacement.
 * @param input <mytag><tag>val1</tag><tag>val2</tag></mytag>
 * @param tag tag
 * @param replacement <tag>val</tag>
 * @return <mytag><tag2>value</tag2></mytag>
 */
public static String replaceGroupTags(String input, String tag, String replacement) {
    Pattern replace = Pattern.compile("<" + tag + ">" + ".*" + "</" + tag + ">");
    Matcher matcher = replace.matcher(input);

    int start = Integer.MIN_VALUE;
    int end = Integer.MAX_VALUE;
    while (matcher.find()) {
        if (start == Integer.MIN_VALUE) start = matcher.start();
        if (end <= Integer.MAX_VALUE) end = matcher.end();
    }
    StringBuffer stringBuffer = new StringBuffer(input);
    return stringBuffer.replace(start, end, replacement).toString();
}
