I have some large svg files I need to edit that crash programs like Inkscape when I try to do much with them, but the changes I want to make are essentially removing bits from them that I don't want which are easily found within the svg if viewed as text,

What I'm looking for is a way to do things like: - completely remove group B which is nested inside group B - remove all "path" elements residing inside group C, unless they match a regex pattern - move all elements from group D into group E (or ungroup them)

I imagine that with the rightXML skillset, which I don't have, this is probably fairly simple?
