hmmmm, Have you tried using FME's built in OSM reader? This might be a nice option for you.

You can save your request from the overpass HTTPCaller to a file rather than an attribute and then a the FeatureReader configured with The OSM XML Format to parse the results for you directly into FME features.

Thank @virtualcitymatt​  , with your idea, I progress a litlle bit. But as you can see (Itried with cemeteries and park), only 31 polygon (only parks) were build. And I don't have name or others informations. For the cemeteries nothing happens and in the featureReader, all features go to Unknown category.

Here the featureReader parameter

So right now it's not so positive ! ;)

Can you share the test.xml file? It could just be there is some more hidden information

@virtualcitymatt​  what do you think about it?

Hey, right yeah seems there is somethign a bit weird going on when using the detfault settings.

I found I got more results if I used the "Output Incomplete Ways and Relations" settings. A lot more retsults here

Yes it works with it! It's better, it think I can progress now.

Thank you @virtualcitymatt​  for your quick answer!
