I'm wondering whether or not I should expect that if I import/adopt a
node from a source DOM, that attributes of type ID on the
imported/adopted nodes should be found by getElementById() in the
destination DOM. The behavior I'm seeing is that getElementById()
fails to find the elemements (null is returned).
Can anyone provide some insight on what I should expect? If the type
of the attributes are not carried over, what is one to do? For
non-HTML DOM's, getElementById() can apply to an attribute of any
name, as long as it was marked as of type ID, so it's not like I
recurse the DOM for "id" attributes, as I might in the HTML DOM.
Actually, when I use the HTML DOM, I seem to have the same problem
and I wouldn't expect it there because if
HTMLDocument.getElementById() can't find an element with an attribute
registered as of type ID with the specified value, it falls back to
recursing the DOM looking for "id" attributes with the specified
value. Why is it not finding the elements? For instance (pretend
these are HTML documents, and note that this is from a conversation
on the XMLC list [1])...
page 1:
-----
<page1>
<node id="wherePage2ContentGoes"></node>
</page1>
-----
page 2:
-----
<page2>
<node id="content">
Stuff to be transferred to page1.
<node id="needToMatch">this node</node>
</node>
</page2>
-----
// import content from page 2
Node destNode = page1.getElementById("wherePage2ContentGoes");
Node srcNode = page2.getElementById("content");
destNode.appendChild(page1.importNode(srcNode, true));
...
// then later:
Node match = page1.getElementById("needToMatch"); // fails (match == null)
Thoughts?
