Hi MaDhAt2r.  This is a fine place for this question.  (Though I see
the list received several copies of your message; not sure if that was
a misconfiguration on your end or the list's.)

I believe you need to remove the space between the " and the <?xml
here.  I haven't tried the rest of your code, but when I insert an
image with this SVG data directly, the *Messages* buffer reports
"Error parsing SVG image".  Removing this space fixes the error and
Emacs appears to render a reasonable image.

Hope that helps!
