KBEC-00213 - Listing plugin procedures using ec-perl and XPATH

Summary

This article shows how to extract a list of procedures from your installed plugin library. The approach applies to extracting data from other XML-generating API commands.

Solution

Use the Perl XPATH methods find() and get_nodelist on API get commands to generate list that can be processed with a for-loop.

Examples

use strict;
use ElectricCommander;
$| = 1;
 
my $ec = ElectricCommander->new();
 
for my $plugin ($ec->getPlugins()->find('//pluginName')->get_nodelist) {
    print "Plugin: ", $plugin->string_value(), "\n";
    for my $procedure ($ec->getProcedures($plugin->string_value())->find('//procedureName')->get_nodelist) {
        print " - ", $procedure->string_value(), "\n";
    }
    print "\n";
}

The above ec-perl code will generate output similar to the following:

 - Create
 - CreateResourceFromVM
 - Destroy
 - List
 - Resume

 - ShutDown
