Generally speaking, if you are getting variable name/value pairs then adding them to the hash is simply a matter of: 

$variables{$varname}=$varvalue;

Because you mention that you don't want to delete variables that are already there, I wonder if you mean that some of the variables you are reading in may already be in the hash. If that is the case, you can make sure they are not in the hash by doing something like this when you assign the values: 

$variables{$varname}||=$varvalue;

[download]

That little ||= keeps a value in the hash if it is there or assigns a new key/value pair if it is not defined yet.

The question here is: What exactly is get_page_content() returning? A scalar? array? reference? If you can tell us this, we can give you a more specific anwer.

Cheers
