Wmf In Xsl, How To Display ?

Hello there, it's my first post on this forum 

Here's the problem I'm facing: I've got some xml files in which there are wmf images that I have to display using XSL-FO in my pdf. The problem is that those images are encoded somehow and I don't know what the code is.

It's a sample tag of this image:

I found some ways of displaying images encoded in base64 in some RFC's by using this: "data:image;base64,[some base64 code]" as an url.

The problem is that the images that I've got to display are not encoded in base64 and I got no idea what to do with them to make them apear in my pdf :(

The code looks like some hexadecimals but I haven't come across with something like that before in encoding images. If some one of U people got any idea how to display this image, or how to convert this code, or maybe what this code could be , I would be grateful.
