+get_property()
+**************
+
+Purpose
+========
+
+get_property(rsyslog_variable, key_str)
+
+Provides ability to get a rsyslog variable or property using dynamically evaluated parameters.
+The first parameter is a valid rsyslog variable or property, the second parameter is a key string, or index value.
+
+
+Example
+========
+
+In the following example, a json string is parsed using parse_json(), and placed into the variable ``$!parsed``.
+The get_property function is then used to get property fields from ``$!parsed``.
+
+.. code-block:: none
+
+   set $.ret = parse_json("{\"offsets\": [ { \"a\": 9, \"b\": 0 },\
+                                           { \"a\": 9, \"b\": 3 } ],\
+                                           \"boolval\": true,\
+                                           \"int64val\": 1234567890,\
+                                           \"nullval\": null,\
+                                           \"doubleval\": 12345.67890 }", "\$!parsed");
+
+   # get different fields from $!parsed here
+   if $.ret == 0 then {
+      # dynamically evaluate different fields in $!parsed
+
+      # do dynamic indexing into array
+      $.index = 1;
+      # set $.ret = { "a": 9, "b": 3}
+      set $.ret = get_property($!parsed!offsets, $.index);
+
+      # set $.ret = true;
+      set $.key = "boolval";
+      set $.ret = get_property($!parsed, $.key);
+
+      # null values are evaluated to empty string
+      # thus below statement will set $.ret to empty string
+      set $.ret = get_property($!parsed, "nullval");
+
+      # evaluates to 1234567890
+      set $.key = "int64val";
+      set $.ret = get_property($!parsed, $.key);
+
+      # using a key variable, evaluates to 12345.67890
+      set $key = "doubleval";
+      set $.ret = get_property($!parsed, $key);
+   }
+
+   # example of dynamically building key value
+   set $.foo!barval = 3;
+   # set $.bar = 3;
+   set $.bar = get_property($.foo, "bar" & "val");
