Re: Tenplates and subtree plugins: msg#00021 java.enhydra.xmlc

That got me on the right track.
Here is the actual method I wrote....

    /** This takes the whatToPutThere element and puts a deep copy
     ** of it under putItHere. Before the insertions all child nodes
     ** of putItUnderHere are removed.
     ** The idea here is to have a template doc with some
     ** DIV tag with an id. You find the div. Then create another document
     ** with the contents for some part of the template, and copy it to
     ** be under the DIV.
     ** <code>
     ** layoutHTML L = new layoutHTML();
     ** indexHTML t = new indexHTML();
     ** // All HTMLElements here are org.w3c.dom.html.HTMLElement
     ** HTMLElement centerMiddle = L.getElementCenterMiddle();
     ** HTMLElement indexMainContents = t.getElementMainContents();
     ** HTMLElement N = replaceNodes(centerMiddle, indexMainContents);
     ** </code>
     ** @returns The new cloned node.
     **/
    public org.w3c.dom.html.HTMLElement replaceNodes(
    org.w3c.dom.html.HTMLElement putItUnderHere,
    org.w3c.dom.html.HTMLElement whatToPutThere) {
        org.w3c.dom.NodeList N = putItUnderHere.getChildNodes();
        while(N.getLength() > 0) {
            putItUnderHere.removeChild(N.item(0));
        }
        org.w3c.dom.html.HTMLElement theNewNode =
        (org.w3c.dom.html.HTMLElement)putItUnderHere.getOwnerDocument().importNode(whatToPutThere, true);
        putItUnderHere.appendChild(theNewNode);
        return theNewNode;
    }

And here is it's use...
            layoutHTML L = new layoutHTML();
            indexHTML t = new indexHTML();
            HTMLElement centerMiddle = L.getElementCenterMiddle();
            HTMLElement indexMainContents = t.getElementMainContents();

            org.w3c.dom.html.HTMLElement newObj = replaceNodes(centerMiddle, indexMainContents);

            HTMLDivElement d = (HTMLDivElement)L.getElementById("testPara1");
            CharacterData cd = (CharacterData)d.getChildNodes().item(0);
            cd.setData("This was changed from original clone text.");

The reason I change the CharacterData after the replaceNodes is that if I was doing
something big like a multi row table from a database, then you avoid copying huge amounts of nodes.

The template HTML (layoutHTML) is
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title></title>

</head>
<body>
<table border="1">
<tbody>
    <tr>
      <td id="leftTop">Left top</td>
      <td id="centerTop">Center top</td>
      <td id="rightTop">Right top</td>
    </tr>
    <tr>
      <td id="leftMiddle">Left center</td>
      <td id="centerMiddle">Center center</td>
      <td id="rightMiddle">Right center</td>
    </tr>
    <tr>
      <td id="leftBottom">Left bottom</td>
      <td id="centerBottom">Center bottom</td>
      <td id="rightBottom">Right bottom</td>
    </tr>
    <tr>
    </tr>
</tbody>
</table>
</body>
</html>

And the indexHTML is

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
    <title>index</title>
</head>
<body>
<div id="mainContents">
    <hr> <div id="testPara1"> This is a test paragraph </div>
    <hr>
</div>
</body>
</html>

I want to take one document called layout.html and another called body.html

with the removed div.
I have code like....
            layoutHTML L = new layoutHTML();
            bodyHTML t = new bodyHTML();
             // The div I want to replace.
            HTMLElement centerMiddle = L.getElementCenterMiddle();
             // The div I want to plug into the layoutHTML object.
            HTMLElement indexMainContents = t.getElementMainContents();


HTMLElement nE = 
(HTMLEelemet.getDocument().importNode(t.getElementMainContents(),true);
cenerMiddle.appendChild(newElement);

bodyMainContents.getParentNode().removeChild(indexMainContents);
centerMiddle.appendChild(t.getElementMainContents());
It compiles and when I run it it says 'wrong document'
It appears that the indexMainContents retains the class id or something
of the
owning document t, and so when L goes to render it'sself to the browser
it recognizes that the nodes are from the wrong doc.


Try someting like those two lines above.
