The template element in HTML 5 is special in the sense that it does not
add its contents into the DOM tree, but instead keeps them in a separate
shadow DOM document fragment. Interacting with the DOM tree cannot touch
the elements in the document fragment.
Closes GH-14906.
It was possible to return false without throwing an exception.
This is even wrong in "old DOM" because we expect either a NOT_FOUND_ERR
or NO_MODIFICATION_ALLOWED_ERR according to the documentation.
A side effect of this patch is that it prioritises NOT_FOUND_ERR over
NO_MODIFICATION_ALLOWED_ERR but I think that's fine.
The xinclude code from libxml removes the fallback node,
but the fallback node is still reference via $fallback.
The solution is to detach the nodes that are going to be removed in
advance.
Closes GH-14704.
This is a long standing bug: IDs aren't properly tracked causing either
outdated or plain incorrect results from getElementById.
This PR implements a pragmatic solution in which we still try to use the
ID lookup table to a degree, but only as a performance boost not as a
"single source of truth". Full details are explained in the
getElementById code.
Closes GH-14349.
If there is no root, the namespace cannot be attached to it,
so we have to attach it to the old list.
This isn't a problem in "new DOM" because namespaces are managed in a
separate structure there.
* PHP-8.3:
Fix crash when calling childNodes next() when iterator is exhausted
Fix references not handled correctly in C14N
Fix crashes when entity declaration is removed while still having entity references

Fix crashes when entity declaration is removed while still having entity references
libxml doesn't do reference counting inside its node types. It's
possible to remove an entity declaration out of the document, but then
entity references will keep pointing to that stale declaration. This
will cause crashes.
One idea would be to check when a declaration is removed, to trigger a
hook that updates all references. However this means we have to keep
track of all references somehow, which would be a high-overhead
solution. The solution in this patch makes sure that the fields are
always updated before they are read.
Closes GH-14089.
* Make (DOM)XPath::quote only accept strings without NULL bytes
The reason is that libxml will cut off on a NULL byte, and so strings
containing NULL bytes may not be necessarily safe even when coming out
of quoting.

The list is live, so upon cache invalidation we should rewalk the tree
to sync the index again with the node list. We keep the legacy behaviour
for the old DOM classes.
Closes GH-13934.
