PERL: Replace multiple objects within a string
looking to replace parameters within a string with an external answer - with multiple replacements within a string %% will be used to wrap the objects to be replaced
i.e. hello %%title%% %%user%% from %%address%% you last %%action%% on %%object%%
the params will be used to make calls to a database to get the answers thenI need to substitute the answers back in.
I think I need to do this in two passed
first extract all the params and process them
then replace each param with it's results
my questions
- how do I get the params out to an array
- how do I substitute them back in
