I am trying to performance a regex on a "string" of text that python isinstance

Here is the "string" of code I am working with:
{'/Title': '1F: Progress Notes Src.: MILANI, JOHN C Tmt. Dt.: 05/12/2014 -
05/28/2014 (9 pages)', '/Page': IndirectObject(465, 0), '/Type': '/FitB'}
I want to grab the name "MILANI, JOHN C" and the last date "-mm/dd/yyyy" as a
pair such that if I have X numbers of string like the above I will end out with N pairs of values
(name and date)/ Here is my code:
import PyPDF2,re
pdfFileObj=open('x.pdf','rb')
pdfReader=PyPDF2.PdfFileReader(pdfFileObj)
Result=pdfReader.getOutlines()
MyDict=(Result[-1][0])
print(MyDict)
print(isinstance(MyDict,dict))
MyRegex=re.compile(r"MILANI,")
x=MyRegex.findall(MyDict)
print(x)
As the error message says, re.findall() expects a string. A dictionary
is in no sense a string, so passing it in whole like that won't work.
If you know that the name will always show up in the title field, you
can pass just the title:
x = MyRegex.findall(MyDict['/Title'])
Otherwise you will have to loop through all the entries in the dictionary:
for entry in MyDict.values():
x = MyRegex.findall(entry)
# ...and do something with x
I rather suspect you are going to find that the titles aren't in a very
systematic format, though.
