Homework 4 had you produce a list of publication IDs from a keyword search on PubMed. The final project is to produce a list of the publication citations for that keyword.

Begin with that program. First, modify it so that after it requests the keywords, it asks the user how many references to print. Be sure the integer is a positive number!

The program will obtain a query string that is a URL of a list of PubMed publication IDs. Use that URL to get the metadata. The web page you get back is an XML document giving details of the publications.

Your job is to print a bibliography from this record. Your entry for each journal should look like this:

A. Bester, R. Zelazny, and H. Ellison, "On the Role of Viruses in Future Epidemics," Journal of Irreproducible Results 3(4) pp. 29-35 (Mar. 2103).
PUBMED: 23456789; DOI 12.1119/2847595.

Then print the abstract, if it is present in the record.

If there is no DOI, use the PII. If neither is there, omit that part of the entry.

You will need to look at the XML records to get the fields. These are delimited by tags with attributes, each of which may have a value. For example, the element

<ELocationID EIdType="doi" ValidYN="Y">10.1016/j.vaccine.2015.04.071</ELocationID>

has a tag of ELocationID, attributes of EIdType (with value doi) and ValidYN (with a value of Y), and the field contains 10.1016/j.vaccine.2015.04.071, which (as the EIdType value indicates) is a DOI.

The easiest way to see what the records look like is to run your program from homework 4 and ask for a single entry. You can then see its structure (you might find the prettyprinter xmlpp.py useful). The fields of interest will have these tags:

Those will be enough to build the reference, as described above.
