Is there a way to use environment variables in .dtd and .xml files. Example: I want to use user dependant files to include private data DTD: <!ENTITY P1 SYSTEM "./Projects.xml"> <!ENTITY HOME SYSTEM "$HOME/Private.xml"> XML file: &P1; &HOME; I read the files, using jdom: SAXBuilder builder = null; builder = new SAXBuilder(); Document doc; doc = builder.build(new File(filename)); XMLOutputter outputter = new XMLOutputter(); Element root = doc.getRootElement(); Element OS; OS = root.g   More>>

			

			DTD:
			

			<!ENTITY P1 SYSTEM  "./Projects.xml">
			

			<!ENTITY HOME SYSTEM "$HOME/Private.xml">
			

			

			

			XML file:
			

			

			

			&P1;
			

			

			

			

			&HOME;
			

			

			

			I read the files, using jdom:
			

			

			

			SAXBuilder builder = null;
			

			builder = new SAXBuilder();
			

			

			Document doc;
			

			

			doc = builder.build(new File(filename));
			

			XMLOutputter outputter = new XMLOutputter();
			

			

			Element root = doc.getRootElement();
			

			Element OS;
			

			OS = root.getChild("Unix");
