I have had some thoughts on how to do this (for my situation anyway)

- Locate a Java utility library that includes base64 decoding (eg
org.apache.axis.encoding.ser.Base64Deserialiser)
- Hook this into OPS by writing a java processor
(http://www.orbeon.com/ops/doc/processors-java)

Not sure if it's suitable for what you are doing.

You are not alone,

just see my posts and post from Boon Low.
We don't know how to do anything else with the imported data but stream
it.
And we need help on that.
Welcome to the club.

Cheers,
Taras

Subject: [ops-users] Decoding base64Binary

I'm calling a web service (SOAP), and the results are returned as
base64Binary.

The results are actually an XML document (this is being encoded by the
web service and returned as a base64Binary stream).

I want to decode the base64Binary data back into an XML document so I
can process it.

I've tried using the oxf:xml-converter, but with no joy.

For example:
==========
    <p:processor name="oxf:xml-converter">
        <p:input name="config">
            <config>
                <content-type>application/xml</content-type>
                <encoding>utf-8</encoding>
                <version>1.0</version>
            </config>
        </p:input>
        <p:input name="data">
            <document
xsi:type="xs:base64Binary">PGRhdGE+ZXhhbXBsZTwvZGF0YT4=</document>
        </p:input>
        <p:output name="data" ref="data"/>
    </p:processor>
==========

In this case, the decoded data is actually:
<data>example</data>

The results of the above are the whole of the data input, as-is,
embedded within <document></document> tags.

I can use the oxf:http-serializer processor to stream the base64 data
straight to the browser and view the XML that way; but I can't figure
out a way of converting it into an XML output that can be consumed by
other processors.
