If the XML is not valid there's a big chance FME won't be able to read it either. You can try this:

Create an XML reader, go into its parameters, set the Configuration Type to Feature Paths, find the Elements To Match setting and set that to setting, then enable flattening in the Flatten Options.

That way FME will try and make attributes out of everything it can find underneath that <setting> tag and you can map it to Excel.

Hope this helps.

Thanks for your hint. I will try this and let you know. :-)

I can transform my xml document ("elements to match" did the trick) to excel but comments are missing.

I will try different settings at reader level to export comments to excel too.

Thank you.

If it's possible upgrade to 2016 that will provide you with a feature introduced in 2016 that scans the schema and returns all the xml elements in the input.

Hope this helps

@itay do you mean that xml reader has a new feature in version 2016? Or is this a completely new reader? Do this read my comments by default or at least easier than in 2015?

@nhaz Its a new 2016 XML reader functionality, see the following article for more info
