delete missing xml link from indd-file / delete xml information

Hello,

I'm currently working on a project that builds catalogs.

The catalogs consist of several different, linked INDD-files.

Now, those INDD-files are filled up with XML data and saved.

When we import them, we always get errors that there is a link missing to the xml. Now, once the indd is filled up, we do not need the xml reference anymore.

I've checked the links-page in indesign, to see if there is a reference to the xml but there is none...

How can I delete all the xml information from a indesign file without loosing the references to a text box or it's structure..

Thanks

Regards

Mario
