xml & java

[emma quinn]

. I have the modulus and exponent of a private key stored as BigIntegers as such:

bigInt = ((RSAPrivateKey)rsaprvkey).getModulus();bigInt1 = ((RSAPrivateKey)rsaprvkey).getPrivateExponent();

Those BigIntegers then need to get passed as a value to two XML nodes

<ds:Modulus>ANiFf8Sbvavjutyj+WBzqrS9yJu0SK2kLiCS/ZCaiBfDRhPIWoBpGmE3GQ6tUO5FEoX5wvqI9DzaZyrLij/qiXs=</ds:Modulus> <ds:Exponent>Aw==</ds:Exponent> 

....and look something like the above.
Not too sure as how to go about passing the values into specific nodes. Any ideas???
