Functionality:
1)This script reads the 'profiles.xml' generated by Crawler_Linkedin.py 
and extracts only the URLs of the public profiles. Finally writes the URL to a file <Sample.txt>.
2)Crawls the linkedin public profile by using the URLs present in the file <Sample.txt> and gets 
the viewers of those profiles. Writes it to a file <Sample1.txt> and get the unique URLs and finally writes it 
to a file <Public_Profiles.txt>
3)Extracts the name,location and skills by parsing them and saves the result in a text file <Linkedin_Results.txt>.

Approximately the script takes 1 to 2 hours to crawl the data, depending on the internet connection and system 
utilization.
