Regex on a Dictionary

[Stanley Denman]

I am trying to performance a regex on a "string" of text that python isinstance is telling me is a dictionary.  When I run the code I get the following error:

{'/Title': '1F:  Progress Notes  Src.:  MILANI, JOHN C Tmt. Dt.:  05/12/2014 - 05/28/2014 (9 pages)', '/Page': IndirectObject(465, 0), '/Type': '/FitB'}

Traceback (most recent call last):
  File "C:\Users\stand\Desktop\PythonSublimeText.py", line 9, in <module>
    x=MyRegex.findall(MyDict)
TypeError: expected string or bytes-like object

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)

Thanks in advance for any help.
