add an inner function to extract tags

MaRDI Pull Request

Changes:

• the inner function should collaborate with the outer function extract tags in getAsXml.py

• it should add the softwares to the openaire set as we already agreed.

I like the function, but it should not be written into another function itself; it can be confusing. Please write add_software(): out of extract_tags(result):

@Mazztok45 i moved the function outside and now it is written separately and only called inside the extract tags function , made another small commit just to correct the blank and whitespaces for deep source warnings sake
