我需要用一些值替换命名空间

     private static String REGEX1 = "(<\\/?)[ns2]+?:";

    private static String INPUT = "<ns1:fso xmlns:ns2='https://www.example.com/fsoCanonical'><ns2:senderId xmlns='http://www.example.com/fsoCanonical'>abc</ns2:senderId><receiverId xmlns='http://www.example.com/fsoCanonical'>testdata</receiverId>   <messageId xmlns='http://www.example.com/fsoCanonical'>4CF4DC05126A0077E10080000A66C871</messageId>    </ns1:fso> ";
    private static String REPLACE = "$1cc:";

    public static void main(String[] args) {
                Pattern p = Pattern.compile(REGEX1);
                Matcher m = p.matcher(INPUT); // get a matcher object
                StringBuffer sb = new StringBuffer();
                while (m.find()) {
                 m.appendReplacement(sb, REPLACE);
               }
                m.appendTail(sb);
              System.out.println(sb.toString());

我需要将我的命名空间从ns2替换为cc，但上面的代码只能替换ns2：到cc：我需要用xmlns替换标签：ns2 = with xmlns：cc = also。请告知如何使用相同的正则表达式替换它。

         <ns1:fso xmlns:ns2='https://www.example.com/fsoCanonical'><ns2:senderId xmlns='http://www.example.com/fsoCanonical'>abc</ns2:senderId><receiverId xmlns='http://www.example.com/fsoCanonical'>testdata</receiverId>   <messageId xmlns='http://www.example.com/fsoCanonical'>4CF4DC05126A0077E10080000A66C871</messageId>    </ns1:fso> "

到

      <ns1:fso xmlns:cc='https://www.example.com/fsoCanonical'><cc:senderId xmlns='http://www.example.com/fsoCanonical'>abc</cc:senderId><receiverId xmlns='http://www.example.com/fsoCanonical'>testdata</receiverId>   <messageId xmlns='http://www.example.com/fsoCanonical'>4CF4DC05126A0077E10080000A66C871</messageId>    </ns1:fso> "

RegEx用于替换XML中的命名空间
