Hi,
In my xml file i have a variable setup as this:
<Logfile path="$(CONFIG.DIR)" />

I have an env variable setup in my windows XP as this:
CONFIG_DIR=C:\MyApp\cfg

In my code for parsing xml i have the following:
org.w3c.dom.Element el = (org.w3c.dom.Element) nodeList.item(0);
m_sPath = el.getAttribute("path");

The variable m_sPath returns null. Any idea what am i doing wrong. Or can anyone suggest how i can get env variables from an xml config file? Help would be greatly appreciated. Thanks.

The code you have shown should return the value "$(CONFIG.DIR)", a string, if the nodeList contains the Logfile element as its first child. XML has no way to evaluate environment variables. You can parse the string to get "CONFIG.DIR" and then use standard Java methods (I assume this is Java, I've never seen org.w3c.dom.Element before) to resolve this variable.

Hi Joe,
Your reply is helpful to me. I am using Java. Could you tell me, if once i get the "Config.dir" string, what java functions could i use to get the "CONFIR_DIR" value? Thanks.

I don't know if there is a cross platform way. Better to ask in the Java forums and state what platform you are running on.
