How can I reliably get the 64bit data from an XML file to a byte[] and then compare that with a string? The following code fails as it seems the whitespace is causing the assert to fail. The goal is for the assert to pass.

Note that it is important that we have it in the form of byte[] at somepoint, but not that the comparison be via strings

<Contents>VGVzdGluZyBURSBzZXNzaW9uIGNvbnRhaW5pbmcgQ29tcGxldGUgUGVyc29uIEEgYW5kIENvbXBs
                ZXRlIEVxdWlwbWVudCBCLg0KDQpUZXN0IFRlc3QNCg0KUmVmZXJlbmNlcyBDb21wbGV0ZSBQbGFj
                ZSBB
            </Contents>

byte[] byteData = document.Contents.text()
assert 'VGVzdGluZyBURSBzZXNzaW9uIGNvbnRhaW5pbmcgQ29tcGxldGUgUGVyc29uIEEgYW5kIENvbXBs'+
                'ZXRlIEVxdWlwbWVudCBCLg0KDQpUZXN0IFRlc3QNCg0KUmVmZXJlbmNlcyBDb21wbGV0ZSBQbGFj'+
                'ZSBB' == new String(byteData)

    Base 64 data is a special encoding of text to ASCII to be URL friendly (historically)

    EDIT thanks to comment below, actually base64 was to encode data to send via for email

    to extract text from your data, do this:

    new String(
'VGVzdGluZyBURSBzZXNzaW9uIGNvbnRhaW5pbmcgQ29tcGxldGUgUGVyc29uIEEgYW5kIENvbXBsZXRlIEVxdWlwbWVudCBCLg0KDQpUZXN0IFRlc3QNCg0KUmVmZXJlbmNlcyBDb21wbGV0ZSBQbGFjZSBB')
.decodeBase64()
)

    result starts with ‘ession containing Complete Person A and Complete Equipment B.’
