hostname substitution to form url in xml
Posted by thierry (thierry), 22 December 2008I have inherited a lovely Nagios install where webinject (http://www.webinject.org/plugin.html) is used to run a series of 20 odd test cases.
Each test case is based on an xml file that contaisn the following stanza:
In their great wisdom the local guys have decided to copy/paste/edit these xml so they have a set of files for each and every $hostname resulting in hundreds of files...
I _know_ there is a better way to do this if I could only learn/understand how to programmaticaly replace $hostname for each server I need to runsaid test for.
Any pointer would be great
Posted by KevinAD (KevinAD), 24 December 2008it is possible to expand a scalar variable in a file using a regular expression with the e option:
my $hostname = 'example.com';
my $text = 'url=http://$hostname:port/path_to_app';
$text =~ s/(\$hostname)/$1/eeg;
How you apply that to your spefic requirements is the trick.
