1. Philosophy
view UML
Programmatically access PubMed article is a common task for me.
Luckily, with the help of eutils,
we can access full article data in XML format.
What I need is Python objects, not just XML strings, so pubmed-mapper was born.

pip install pubmed-mapper

infile = 'xxx.xml'
with open(infile) as fp:
root = etree.parse(fp)


articles = []
for pubmed_article_element in root.xpath('/PubmedArticleSet/PubmedArticle'):
article = Article.parse_element(pubmed_article_element)
articles.append(article)
