Hey guys,
Yesterday I had nothing to do, so I decided to create a cartoon using inkscape.
I saved it and closed Inkscape. Nothing wrong witch that.
My actual problem is that I can't open it. when I tried to open it, it said that the file wasn't a valid XML-file.
I treid dragging it into inkscape and I looked in 'recent projets' but it didn't work.
I spend ike 4 or 5 hours on this project, so would be pleased if someone could help me out with this!
greets,
SuperInkscapeMan

Hi.

Sounds it got corrupt. Usual scenario is when the save was not complete, meaning some parts of your file are missing preventing it from opening/rendering.
Svg files are xml documents, if you open it in a notepad it should end with a </svg> tag.
If it is missing, and other parts as well before it, you should add the tag.
Maybe even needs deleting "chopped in half" object and closing other groups with tags too.

Can you share the file?

Also activate autosave to not loose any more work, but to keep snapshots of your work. Never close Inkscape too early while it is still saving.

Edit -> Preferences -> Input/Output -> Autosave

I think a lot of people have workflow:

work, work, work, look over work, save, close

better would be:

work, work, work, save, look over work, close

or if it's already a large file that is challenging resources (Inkscape going slow):

work, save, work, save, work, save, look over work, close

I use a tool like prettyprinter XML in the editor I use (Geany). It gives me the line number in which the mistake is found.
Furthermore, you can use the W3C-validator. If the file is corrupt, it will give you the place where it has found mistakes.
Another thing. Inkscape can be quite forgiving in depicting images that are technically not correct. But the start of the file must be entirely correct. It must be like this:

If the error is indeed to be found in the start of the file, replace it with above mentioned code. You can then change the width and the height of the image after you have opened the image in Inkscape.
Btw, you can always give the output of the errormessage in this forum.
