Changing Identifiers/paths when extracting text from pdf

Hello,

Iam a bit new to adobe.

Iam working on a project to read out text/table information from pdf, extract it via python-SDK and use the extracted information to create new data sets in an external system.

PDFs are created via web forms from adobe. I want to retrieve these documents using the v6 sign api.

Currently Iam working with local pdf files.

I have tried out plenty of standard-functions, however they all seem to have the same problem. I don't get consistent identifier for objects/paths, if some of the optional form-content won't be filled.

Example:

We are asking for customer names in the formular. If one of the optional check boxes aren't ticked I do receive different object-IDs. Also the provided path-information is differentiating.

Additionally I expected just to have a NULL-value or something else if an optional content is not provided. However, It won't get listed at all.

Is there a function that avoids this behavior?

Regards

Patrick
