| SVG files I have are roughly of the form
| 
| <?xml version="1.0"?>
| <!DOCTYPE svg   ...
| <svg   ...
| 
| with the all the usual variations from the <?xml ?>
|

| <!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.0//EN"
|         "http://www.w3.org/TR/2001/REC-SVG-20010904/DTD/svg10.dtd";>
| 
| The <svg> almost always includes extra information, some kind of height
| width dimenions or a view box size.
| 
| Quite a few programs insert a comment between the doctype and the <svg>
| tag and put some sort of advertising/generator information there.
|

Why don't you try a "search" match?
