Probably different versions of `rebot`?
Try:
```python
python -m robot.rebot --merge lst_output_01.xml lst_output_02.xml
```

Hi,
Does a simple file rebot (with for example just another output.xml file) works?
```
rebot --output test.xml your file.xml
```
And what is the RF version, and rebot as well?
Regards
Charlie

Hi Charlie
Your command not work, same error…
Seams that the issue is related with the xml file.
The RF version is 6.0.1 and I’m using Rebot from the RF version installed.
Thanks

output.xml has been changed between 6 and 7.0 releases. Check your output.xml files and there should be a xml tag at the top of the file which says something along the lines:
```python
```
generator attribute highlights which version of robot was used to to generate that file and also schemaversion plays into that.
Typically you would use the same version of rebot as the one that was used to generate the output.xml.
However, if you need to run newer robot, you can use `--legacyoutput` command line argument to robot itself so that the output.xml will be compatible with older robot/rebot. But as said, that needs to be decided before you run your tests/output.xml is generated.

Issue solved.
The problem was related with the version of Rebot that was not compatible with version of RF output.xml.
Thanks Rasjani for the support.

This means you have different installations, like I first suggested 🙂
