fixed bugs where methods were being called on NoneType objects #73

Closed nicford closed 4 years ago

nicford commented 4 years ago

I was parsing some data from PubMed and found a few cases where there was some missing information in the xml tags causing NoneType to be returned, therefore causing methods to be called on NoneType objects during runtime, causing the program to crash. I added some additional checking for NoneType to overcome this.

Thanks so much @njford!
