java - Regex to remove the uri prefix (within tag) only from xml tag -

i need regular expression remove uri prefix(within tag) xml tag.

example

here code:

import java.util.regex.matcher; import java.util.regex.pattern;  public final class regularexpressiontest {      private static string regex1 = "<\\/?([a-z0-9]+?:).*?>";      private static string input = "<ns1:fso xmlns:ns1='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 = "";    public static void main(string[] args) {       pattern p = pattern.compile(regex1);     matcher m = p.matcher(input); // matcher object     stringbuffer sb = new stringbuffer();     while (m.find()) {       m.appendreplacement(sb, replace);     }     m.appendtail(sb);     system.out.println(sb.tostring());   } 

i not able paste input xml here

private static string input =

is not correct 1 shown in above code. instead can take example of soap message.

i more used perls regex engine, if works same, it:

private static string regex1 = "(<\\/?)[a-z0-9]+:"; 

and

private static string replace = "$1";
