><P
> This functions appends a child to an existing list of children or creates
a new list of children. The child can be created with e.g.
<B
CLASS="function"
>domdocument_create_element()</B
>,
<B
CLASS="function"
>domdocument_create_text()</B
> etc. or simply by using any
other node.
</P
><P
> (PHP < 4.3) Before a new child is appended it is first duplicated. Therefore the new
child is a completely new copy which can be modified without changing the
node which was passed to this function. If the node passed has children
itself, they will be duplicated as well, which makes it quite easy to
duplicate large parts of a xml document. The return value is the
appended child. If you plan to do further modifications on the appended
child you must use the returned node.
</P
><P
> (PHP >= 4.3) The new child <TT
CLASS="parameter"
><I
>newnode</I
></TT
> is first
unlinked from its existing context, if it already existed in a document.
Therefore the node is moved and not copies anymore. This is the behaviour
according to the W3C specifications. If you want to duplicate large parts
of a xml document, use DomNode->clone_node() before appending.

> The following example will add a new element node to a fresh document
and sets the attribute "align" to "left".

The above example could also be written as the following:
<TABLE
WIDTH="100%"
BORDER="0"
CELLPADDING="0"
CELLSPACING="0"
CLASS="EXAMPLE"
><TR
><TD
><DIV
CLASS="example"
><A

><?php
$doc = domxml_new_doc("1.0");
$node = $doc->create_element("para");
$node->set_attribute("align", "left");
$newnode = $doc->append_child($node);
?></PRE
></TD
></TR
></TABLE
></DIV
></TD
></TR
></TABLE
>
A more comples example is the one below. It first searches for a certain
element, duplicates it including its children and adds it as a sibling.
Finally a new attribute is added to one of the children of the new
sibling and the whole document is dumped.
<TABLE

><B

></P
><TABLE

BGCOLOR="#E0E0E0"
CELLPADDING="5"
><TR
><TD
><PRE
CLASS="php"
><?php
include("example.inc");
if(!$dom = domxml_open_mem($xmlstr)) {
echo "Error while parsing the document\n";
exit;
}
$elements = $dom->get_elements_by_tagname("informaltable");
print_r($elements);
$element = $elements[0];
$parent = $element->parent_node();
$newnode = $parent->append_child($element);
$children = $newnode->children();
$attr = $children[1]->set_attribute("align", "left");
echo "<PRE>";
$xmlfile = $dom->dump_mem();
echo htmlentities($xmlfile);
echo "</PRE>";
?></PRE

The above example could also be done with
<B
CLASS="function"
>domnode_insert_before()</B
> instead of
<B
CLASS="function"
>domnode_append_child()</B
>.
