Exchanges will usually publish an up-to-date list of securities on their web pages. For example, these pages offer CSV downloads:

• http://www.nasdaq.com/screening/companies-by-industry.aspx?exchange=NASDAQ&render=download
• http://www.nasdaq.com/screening/companies-by-industry.aspx?exchange=NYSE&render=download
• http://www.asx.com.au/asx/research/ASXListedCompanies.csv

NASDAQ Updated their site, so you will have to modify the URLS:

NASDAQ

• https://old.nasdaq.com/screening/companies-by-name.aspx?letter=0&exchange=nasdaq&render=download

AMEX

• https://old.nasdaq.com/screening/companies-by-name.aspx?letter=0&exchange=amex&render=download

NYSE

• https://old.nasdaq.com/screening/companies-by-name.aspx?letter=0&exchange=nyse&render=download

Depending on your requirement, you could create the map of these URLs by exchange in your own code.
