Thanks, but it did not solve my problem!
I have a file like:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE standard [
	<!NOTATION GIF SYSTEM "GIF">
	<!NOTATION EPS SYSTEM "EPS">

	<!ENTITY SLE47659 SYSTEM "47659.eps" NDATA EPS>
	<!ENTITY SLE42925 SYSTEM "42925.gif" NDATA GIF>
]>
<standard>
	<graphic ent="SLE47659"/>
	<graphic ent="SLE42925"/>
</standard>

and I want in the output file the content of the files in base64 encoded. 
First step is to resolve SLE47659 to 47659.eps. 2. Step read the file and 
encode it as base64. All within XSLT. Step 2 is covered by you and I found a 
algorithm from Oleg, too. But that does not help without step 1!
Do you have a base64 encoding in VBScript? Then I could embed it in MSXSL 
4.0. There I can do the 1. step.
Thanks Harald
