I have a text file scrapped from my email which contains 1 attachment/mail. The attachment is present under different names with totally different formats, ex.:
filename="John_wheeler 11041997 resume.pdf";
filename="Kujal_newResume(1).pdf";
filename=JohnKrasinski_Resume.pdf
My question is: is there any way to find a RegEx pattern that would start searching from filename= and go until the dot character (that separates from file extension)? Getting file extension would be next task, but I can hold that for now. Please help me figure this out.

You could try this pattern: filename="?([^.]+)
It assumes that dot separates filename from extension.
Explanation:
filename="? - match filename= literally and tehn match 0 or 1 apostrophe "
([^.]+) - match one or more characters that is not a dot (match everything until dot) and store it in capturing group
Your desired filename will be stored in capturing group.
Demo
EXTRA: to capture also file extension, you could use such pattern: filename="?([^.]+).([^";]+)
Additional thing here is .([^";]+): matches dot literally with .. Then it matches one or more characters other than " or ; with pattern [^";]+ and stores it in second capturing gropup.
