I got a problem when trying to write a new node to an xml file, basically the new node isn't appended to the file. I tried to write to another file, but in both cases, only the old data appears... what am I doing wrong? :S


Here's my code:

Thanks in advance.

Try appending the XmlDataElement created to the document.

Thanks for your reply... done, I got:

org.w3c.dom.DOMException: HIERARCHY_REQUEST_ERR: An attempt was made to insert a node where it is not permitted.
at com.sun.org.apache.xerces.internal.dom.CoreDocumentImpl.insertBefore(CoreDocumentImpl.java:391)
at com.sun.org.apache.xerces.internal.dom.NodeImpl.appendChild(NodeImpl.java:235)

Then try where you have to append the XmlDataElement. If that should be under the root, then get the doc.getDocumentElement() and append the XmlDataElement to it.

Hi John: Fine, that works; I was deducing when I call "Element XmlDataElement = doc.createElement("XmlData");" DOM knows both is a new node, and where I wanna put the new node (considering is the next new node inside the document) but it is not the case. Here's the new code calling the root node and appending a new XmlData node to it, that solution worked for me (Lines 34, 35):

Again, thanks so much for your help.
