Hmmmm...
Unless I'm mistaken the following line should if working correctly return only import the header element. Not sure why the whole document would be imported. Maybe it has something to do with the fact the the node being imported has the same id as the node it is getting inserted into. Not sure. Anyone else see the problem here? Maybe try changing the id value in your design.html to something like.
headerFooter.html
<body>
<div id="dynheader">Header content</div>
</body>
Node headerNode = returnHtml.importNode(headerFooter.getElementHeader(),true);
node.appendChild(headerNode);
returnHtml.html
<body>
<div id="header">
<div id="dynheader">Header Content</div>
</div>
</body>
It looks as if the <div id="header"> element of your page.html is no
longer part of the output. I'm woundering if at compile time empty
nodes are being eleminated from the XMLObject. You might also try the
following.
design.html
<body>
<div id="dynheader">header content</div>
<body>
Page.html
<body>
<div id="header">HEADER GOES HERE</div>
</body>
Actually leave the text "HEADER GOES HERE" in the div. Then after
appending the dynheader element remove the first node. Just a thought.
Node headerNode = returnHtml.importNode(headerFooter.getElementHeader(),true);
node.appendChild(headerNode);
node.removeChild(node.getFirstChild());
