Re: [dom4j-user] Adding a node to the middle of a pre-existing DOM

Hey Doug   The first thing is to find the Element which is going to be the parent to which you are going to add a new element. The selectSingleNode() returns a Node because you could be finding the document ("/") or an attribute ("/foo/@x"), a namespace node ("namespace::*") or text node (":/foo/bar/text()"etc   So you just need to cast it if you know, from the XPath expression, that its going to be an Element.   e.g.   Element parent = (Element) doc.selectSingleNode(     "//server_request/server/weblogic/internal" ); // add a new element parent.addElement( "server_address" ).addText( "192.10.20.41" );   The last add line could be more verbose if you wish. e.g.   Element serverAddress = parent.addElement( "server_address" ); serverAddress.addText( "192.10.20.41" ); James ----- Original Message ----- From: Doug Hoppes To: [EMAIL PROTECTED] Sent: Monday, October 15, 2001 10:33 PM Subject: [dom4j-user] Adding a node to the middle of a pre-existing DOM Hi all,       Just started playing with Dom4J and pretty impressed with it, so far. Question: I have a extremely large Xml object where I want to add an element to the middle of the Dom tree.  What's the most efficient way of doing this?    For example, I want to create an element called <server_address>192.10.20.41</server_address> (where 192.10.20.41 is the text node) to <server_request><server><weblogic><internal>.... I was trying to use the selectSingleNode("//server_request/server/weblogic/internal") to get a Node() and use the addElement(), but the Node class doesn't have the addElement() method.   Could someone post the code for creating an element in the middle of a Xml Dom if I know what the XPath is to the parent element?   Any help is appreciated.   Doug Hoppes
