You seem to randomly mix "myGedcomName" and "myGedcomFile". I'm not sure if
that is intentional, but if it is, you of course can't check if you have a
nome myGedcomFile by using nodeExists(myGedcomName) - that doesn't even
make any sense. The use of nodeExists is to check if a node exists.
Obviously, nodeExists will return false if the node does not exist, and
obviously, if you want it to return true, you have to call if after you add
the node.

Your question is confusing and seems to lack some detail that you consider
obvious and didn't include. You describe the normal and expected behaviour,
and then ask "what the use of that" is, which makes no sense to me. The use
of nodeExists is exactly the use you have described in the lines above. You
can use it the way you do and the answer to your question "how can I test
whether I have already data" is "with the code you provided above".

More details seem to be needed, as that is likely not what you wanted to
hear.

Liebe Gruesse,
