Replacing strings in a text (likely an XML) file. Some newbie
if line.find(newstring) != -1:
print 'match at line'+str(counter)
newline = line.replace(oldstring, newstring)
Question1: The replace method - If a string does not have the target
replacement "newstring", then newline equals oldstring? Ie. oldstring
is not changed in any way? Seems to be what I observe but just want to
Question2: I'm using "line.find(newstring) != -1..." because I want
to print when a replacement happens. Does "line.replace..." report
indirectly somehow when it replaces?
P.S. I know I should be using XSLT to transform XML - but the above
seems to work for small text changes.
