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());

When I do this, it's inserting the entire document
starting from the specified div to the destination
document. That's confusing. Let me show an
example...
My design.html: (the equiv of your headerFooter.html)
----
<html>
<head>
<title>Design template</title>
</head>
<body>
<div id="header">
This is the header for <span id="siteName_1">Widgets
R Us</span>.
</div>
<div id="footer">
This is the footer for <span id="siteName_2">Widgets
R Us</span>.
</div>
end of doc
</body>
</html>
----
My page.html:
----
<html>
<head>
<title>My page</title>
</head>
<body>
<div id="header"></div>
<div id="content>
Page content here
</div>
<div id="footer"></div>
</body>
</html>
----
When I appendChild() the header node from design.html
to the header node of my page.html, what gets inserted
is:
----
<div id="header">
This is the header for <span id="siteName_1">Widgets
R Us</span>.
</div>
<div id="footer">
This is the footer for <span id="siteName_2">Widgets
R Us</span>.
</div>
end of doc
----
Obviously, what I want it to insert would just be:
----
<div id="header">
This is the header for <span id="siteName_1">Widgets
R Us</span>.
</div>
----
...or even more ideal would be just the contents of
the header div, but I can live with the div tags in
there too.
It doesn't just append the contents of the header div,
it appends EVERYTHING after it. Ditto for footer.
When I appendChild() the footer info, what gets
inserted is:
----
<div id="footer">
This is the footer for <span id="siteName_2">Widgets
R Us</span>.
</div>
end of doc
----
I'm calling importNode() just like you are. I could
get around this by having separate header.html and
footer.html files, but gross! I must be doing
something wrong. Apparently the "node" that you get
back is really a pointer to the rest of the tree,
including nodes at lower depths. How
counter-intuitive!
Any ideas?
Thanks,
Erik
