Base64 decoding

Hello,

is it possible to decode this type of a soap post request on LTM. Section base64Content needs to be decoded. Any idea for an iRule?

POST /upload/documents HTTP/1.1
    Accept-Encoding: gzip,deflate
    Content-Type: text/xml;charset=UTF-8
    SOAPAction: ""
    Content-Length: 623
    Host: avtestsoap
    Connection: Keep-Alive
    User-Agent: Apache-HttpClient/4.1.1 (java 1.5)

    soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:doc="http://xxxxxx/documents"
       soapenv:Header/
       soapenv:Body
          doc:storeDocumentRequest

    Use an appropriate HTTP event handler

    something like this:

        when HTTP_REQUEST {
    set header HTTP::header "XYZ" 
   log local0. "This is the header before b64 decoding"
    set headerb64decode  [b64decode $header]
   log local0. "This is the header b64 encoded
