Replace data in text node

[ceyesuma]

When Using DOM can the text in <linkDesc>[url]www.deleteme.com[/url] desc</linkDesc> be replaced or will the link element need to be
Removed and replaced?

<?xml version="1.0" encoding="utf-8"?><links>
<links>

<link action="save">
<linkName>www.deleteme.com name</linkName>
<linkPath>www.deleteme.com</linkPath>
<linkDesc>www.deleteme.com desc</linkDesc>
</link>

</links>

thanks

which programming language do you use
with xsl no problem

Java and I just started using DOM I need to fight it for a while to learn basics.
I have a working solution. It may be over kill but it ends up rewriting xml
I'll post the example.

original xml
NOTE: The linkDesc will be altered.

<?xml version="1.0" encoding="utf-8"?>
<links>
  <link action="save">
    <linkName>[e-mail]</linkName>
    <linkPath>[e-mail]</linkPath>
    <linkDesc>User Email</linkDesc>
  </link>
  <link action="save">
    <linkName>[e-mail]</linkName>
    <linkPath>[e-mail]</linkPath>
    <linkDesc>User Email</linkDesc>
  </link>
  <link action="save">
    <linkName>www.hotmail.com name</linkName>
    <linkPath>www.hotmail.com</linkPath>
    [b] <linkDesc>The original description.</linkDesc> [/b]
  </link>
</links>

find the element and save the data in text nodes and introduce new data to the linkDesc tag

private void processForEdit(Element e) throws FileNotFoundException{
        if (e != null) {
            child = e.getChildNodes();




            for (int z = 0; z < child.getLength(); z++) {
                Element element = (Element) child.item(z);
                String name = element.getTagName();
               

                if (element.getNodeName().equals(LINKNAME)) {




                    if (element.TEXT_NODE > 0) {
                        value = getTextValue(child.item(z));
                        if (value != null) {
                            setLinkName(value);
                        }
                    }



                }
                if (element.getNodeName().equals(LINKPATH)) {

                    if (element.TEXT_NODE > 0) {
                        value = getTextValue(child.item(z));
                        if (value != null) {
                            setLinkPath(value);
                        }
                    }


                }
                if (element.getNodeName().equals(LINKDESC)) {

                    setLinkDesc(OpenURLListSelectionPanel.descTxtField.getText());
                 

                }




            }
           
            Document thisDoc = getDoc();
            root.removeChild(e);
            NoteRewriteElementXML nre = new NoteRewriteElementXML();
            nre.appendToOriginalXMl(thisDoc, linkName, linkPath, linkDesc);
        }

    }

change the document,transform the doc and rewrite the xml

public NoteRewriteElementXML() throws IOException{

    }

    public void appendToOriginalXMl(Document doc,String linkName,String linkPath,String linkDesc) throws IOException {

        MusicSystemsJDesktopManager.setCurrentFrame(frame);
        frameName = frame.getTitle();
        JTabbedPane pane = (JTabbedPane) frame.getContentPane().getComponent(0);
        int index = pane.getSelectedIndex();
        tabName = pane.getTitleAt(index);

     
       addFragment(doc,linkName,linkPath, linkDesc);
        

        //set up a transformer
        TransformerFactory transfac = TransformerFactory.newInstance();
        Transformer trans = transfac.newTransformer();
        trans.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
        trans.setOutputProperty(OutputKeys.INDENT, "yes");


        //create string from xml tree
        StringWriter sw = new StringWriter();
        StreamResult result = new StreamResult(sw);
        DOMSource source = new DOMSource(doc);

        trans.transform(source, result);
        xmlString = result.getWriter().toString();
