I am trying to cut out a part of an existing SVG, because I don't need the full SVG.
I am new to Inkscape, but have spent the whole day looking at tutorials and videos to get this done, but I can't see how it is possible without doing a large amount of work - work I don't mind doing, but would rather NOT do

I Also found a tutorial, specifying that it is possible to use Object > Clip > Set. Unfortunately the actual data will remain and the image would therefore not be optimal for the web in this form.

I am using Inkscape version 0.48.4 r9939 on Windows 7.
