Default Add/extract info and file in/from XML

Good evening everibody.
Since I have never used XML in conjunction with Delphi, I can say that I'm a total newbie in this area.
Can anybody help me with some example of how to store the following elements in an XML file (and how to extract them from there):
- file name
- file size
- binary file (some jpg, doc or exe, not a plain file)


Something like this (if you take the content of filecontent and save it in a icon.jpg file you will get exactly the picture:

HTML Code:
<?xml version="1.0" encoding="iso-8859-1"?>
<file>
  <filename>Icon.jpg</filename>
  <filesize>1421</filesize>
  <filecontent> JFIF  ` `   C

It seems like working with binary files is a damn hard work. Never worked it out...
So I've decided to convert binary to Base64 prior to store in XML, and convert back to binary when read.
This way I've overcomed many problems.
I will let this thread open just in case somebody will came with a solution to this problem for future questions ...
