ED data type with (long) base64 data #45

I'm currently looking at parsing data that looks like this:

This is a base64-encoded json string. I got this from a data sheet, not sure what character there should be at the line ends.

If I feed this into the hl7apy parser, it only yields data from the first line in the result and ignores all the subsequent lines' encoded data.

Not sure right now if I am doing something wrong or whether this is just not supported?

I also tried feeding this as a single line (removing all line endings), but then it complains about a too long string.

Hi @ThomasWaldmann, sorry for the late answer. I tried to parse your segment and I succeeded. This is the code I used:

from hl7apy.parser import parse_segment
obx = "OBX|22|ED||HGRAM|eyJQTFQiOiB7ImNvdW50IjogODAsICJtaW4iOiAwLCAibWF4IjogMzAsICJmaWx0ZXIiOiA3LCAiZGlzYyI"\

obx_s = parse_segment(obx)
print(obx_s.obx_5.to_er7())

Can you explain more precisely the problem you're experiencing?
