Description

This filter encodes and decodes a binary resource into and from base64 encoding.

Encode a resource into base64

<b:encode href="{resource uri}" mime="{mime type}" suffix="{filename suffix}" xmlns:b="http://www.xmlpipe.org/xpe/base64" />

The above XML fragement instructs the filter to encode the resource specified by the href attribute to base64 encoding. The filter changes the above XML fragment into:

   <b:base64 mime="{mime type}" xmlns:b="http://www.xmlpipe.org/xpe/base64" >
      {base64 string}
   </b:base64>

Decode base64 into resource

Applying the filter to a base64 element:

   <b:base64 xmlns:b="http://www.xmlpipe.org/xpe/base64" >
      {base64 string}
   </b:base64>

turns the xml fragment into:

<b:resource href="{resource uri}" mime="{mime type}" xmlns:b="http://www.xmlpipe.org/xpe/base64" />
