Am wanting to open and re-save as Inkscape an old Sodipodi graphic which served as the master for my website. It starts out like this...

<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG August 1999//EN"
"http://www.w3.org/Graphics/SVG/SVG-19990812.dtd">
<svg
style="fill:#000000;fill-opacity:50%;stroke:none"
id="svg1"
sodipodi:docbase="/home/aplonis/Desktop/SVG_Projects/"
sodipodi:docname="/home/aplonis/Desktop/SVG_Projects/bike_map_b.svg"
xmlns="http://www.w3.org/Graphics/SVG/SVG-19991203.dtd"
xmlns:sodipodi="http://sodipodi.sourceforge.net/DTD/sodipodi-0.dtd"> <sodipodi:namedview
id="base">
</sodipodi:namedview>

So. Is there any question, anything to be answered?
I cannot see anything defining the drawing itself in those.
An empty file can have such lines too.

It is a complete file (32,494 bytes) and even displays (if a bit off center) as an icon when dropped onto my Ubuntu desktop. It and another similar one are the masters for the maps of my motorcycle-trip website which I'd not updated in a while but was wanting to do again. I had begun it in Sodipodi and was really quite sure that sometime since then had updated in in Inkscape. I'd assumed it to now be an Inkscape file, but on looking inside I see "sodipodi" tags. This is the smaller of the two. Here are links to the SVG and the PNG of which it is master.

Here is what I could do about it.
Had to replace some parts of the svg for inkscape to open.

I don't have the fonts you used and somehow the dragon text appears in one row.
Changed some fills and deleted an unnecessary part -short pink path off the image borders-.

That's great! Thank you.
