Not if the SVG file looks like this:
<!-- image goes here -->
This is almost certainly what happened to those images by Christopher
Fynn - his files appear to be made by CorelDRAW, and CorelDRAW really
does write an empty <metadata> tag right after the opening <g> tag,
The only correct thing to do here is to use an XML parser. But as a
quick fix, most of the problems would be avoided if you could modify
the regular expression so that it doesn't match empty tags.

That was quick! Yes, this is better than just saving the SVG files.
