The Pythonic way to do this is to iterate through the lines of htmlSource and process them one at a 
htmlSource = htmlSource.split('\n')  # Split on newline, making a list of lines
for line in htmlSource:
   # Do something with line - check to see if it has the text of interest

You might want to look at Beautiful Soup. If you can find the links of interest by the tags around 
them it might do what you want:
