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
