Pass integers to datetime.date function

[scidam]

I would note the following: 1) OP tries to parse xml file and assume that if <wp:post_date> is in x, then x should contain some data. x is a string and might include just <wp:post_date> tag. I would recommend to use xml-parser instead; (the same is true for title tag) 2) It is recommended to open files using with keyword.
