Incomplete abstract

[nleguillarme]

While iterating on articles resulting from a PubMed query, I also noticed that the abstract is sometimes incomplete :

For instance :
Query : ((Haliaeetus leucocephalus[Title/Abstract])) AND ((prey[Title/Abstract]) OR (diet[Title/Abstract]))

Returns (when printing first 10 results) :
pubmed_id = '31015971'
abstract = 'Bald eagle ('

The problem is that the package get the text of abstracttext tag and in the example there is some html tag there. see here:

I changed the line 156 in api.py to:
response = re.sub('<[/ ]*[a-z]{1,3}>', '', str(response.text))
return response

Many abstracts and titles are truncated.

It seems a useful solution for most of articles.
But not good for math articles with `<mml:math ....> tags.
Anyway I suggest to merge this one to have a significative fix so far.
