Re^2: Perl XML "dynamic paths "?

Sorry for the late answer. This is example of my config, a node number is the $VAR, in my case. I may need to use config options from <node3> or <nodeN>, that's why I need some sort of variable I guess.

<?xml version='1.0'?>
<regions>
  <node3>
    <instance_num>0</instance_num>
    <common_db_template>165.sql</common_db_template>
    <lib_db_template>165b.sql</lib_db_template>
    <region>node3</region>
    <region_db_host>192.168.38.1</region_db_host>
    <region_db_port>3306</region_db_port>
    <region_name>node3.test.com</region_name>
    <region_prefix>Nd3_</region_prefix>
  </node3>
  <node4>
    <instance_num>0</instance_num>
    <common_db_template>165.sql</common_db_template>
    <lib_db_template>165b.sql</lib_db_template>
    <region>node4</region>
    <region_db_host>192.168.22.1</region_db_host>
    <region_db_port>3308</region_db_port>
    <region_name>node4.test.com</region_name>
    <region_prefix>Nd4_</region_prefix>
  </node4>
  <node5>
    <instance_num>0</instance_num>
    <common_db_template>165.sql</common_db_template>
    <lib_db_template>165b.sql</lib_db_template>
    <region>node5</region>
    <region_db_host>192.168.1.1</region_db_host>
    <region_db_port>3306</region_db_port>
    <region_name>node5.test.com</region_name>
    <region_prefix>Nd5_</region_prefix>
  </node5>
</regions>

If all you need is one specific element of your path to change, then using `->{$VAR}->` already is enough. See Data::Dumper for getting output of a Perl data structure, and References Quick Reference for how to use references. References are what XML::Simple returns.	[reply] [d/l]
