How to make a string substitution in a very long string in Perl?

Tolgar asked
Last Modified: 2012-08-17
I have a very long string and in that string I have the following pattern in most places.


Open in new window

I'd like to convert this types of patterns to the following form:

Open in new window

How can I do it?

I tried the following but it did not work:

$fileLine =~ s{ href=\w+_20 }{\ /20};

Open in new window

The directory names (dir1, dir2, dir3) may change so the rule should be something like this?

Replace between href="file:///// and 20YYMMDD_HHMM with ***
