Cannot parse document: Content is not allowed in prolog.

Hello,

I cannot access my Processes and data within Rapid miner anymore. I copied the whole repository manually in a repository folder on a different computer before, which obviously was a bad idea, because the error occured right after this. The .property and .rmp files are still in my local repository folder I just cannot open them in Rapid Miner. Does anyone know how I can open them again?

The error message is the following:

Exception: com.rapidminer.tools.XMLException
Message: Cannot parse document: Content is not allowed in prolog.

    hi @knoblauch hmm that is not great. Please try this:

    1. Quit RapidMiner.
    2. Make a backup of your complete .RapidMiner folder somewhere else on your drive and then deleting everything in it.
    3. Restart RapidMiner.
    4. RM will rebuild your .RapidMiner folder now - you will need to enter all your license info, etc...
    5. You should be up and running now. Once you're sure you are, open a new local repository and point it to your backup.

    You can also try to open the .rmp files (the RapidMiners processes) with a Text Editor of your choice. The Processes are stored in XML format. Maybe copying corrupted something there.
    You can try to copy the XML content and paste it in the XML view in RapidMiner Studio. When the process XML is valid and you click on the green checkmark the process can be inspected in the design perspective.
    Happy Mining,

    Hi,

    thanks a lot for your answers. Unfortunately @Marco_Boeck is right. The copy operation broke my files and they are all empty now. There was no way to recover the files so I had to start from scratch again. So be careful with copying repository folders.

    Best,
    Hannah
