Masking password for logging

Dear all,

I have a question on masking password for logging

When putting this message (in string format) to log,
<ConfigDetails><ConfigGroup name="configgp1"><LastUpdateTimestamp>Tue Sep 29 11:57:17 HKT 2009</LastUpdateTimestamp><Config key="USERNAME" value="testing"/><Config key="PASSWORD" value="abcd1234"/></ConfigGroup></ConfigDetails>

it is required to change to:
<ConfigDetails><ConfigGroup name="configgp1"><LastUpdateTimestamp>Tue Sep 29 11:57:17 HKT 2009</LastUpdateTimestamp><Config key="USERNAME" value="testing"/><Config key="PASSWORD" value="********"/></ConfigGroup></ConfigDetails>

How can I extract the config key "PASSWORD" and change its value to all *?

Thanks:):):):):):)

Review the String class API... like String.subString(...) and String.indexOf(...)
