DomNode->append_child

Adds a new child at the end of the children ()

Example 564. Adding a child

copy to clipboard

<?php

$doc = domxml_new_doc("1.0");
$node = $doc->create_element("para");
$newnode = $doc->append_child($node);
$newnode->set_attribute("align", "left");
?>

Example 565. Adding a child

copy to clipboard

<?php

$doc = domxml_new_doc("1.0");
$node = $doc->create_element("para");
$node->set_attribute("align", "left");
$newnode = $doc->append_child($node);
?>

Example 566. Adding a child

copy to clipboard

<?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");

$xmlfile = $dom->dump_mem();

echo htmlentities($xmlfile);
?>

Be careful of the order you append childs. (PHP <= 4.2) If you create let's say: $x_html = $x_doc->create_element('html'); $x_head, $x_title, $x_meta, $x_link and $x_body in the same way. If you: $x_head->append_child($x_title); $x_head->append_child($x_meta); $x_head->append_child($x_link); $x_html->append_child($x_head); $x_body_backup = $x_html->append_child($x_body); /* here */ $x_doc->append_child($x_html); If you now try to modify $x_body_backup.. it will no longer be able to modify the actualy XML tree, because you appended the HTML tree to the DomDocument.. and it has copied ALL the nodes at the end of the DomDocument, so the reference you now have in $x_body_backup is not valid anymore! If you had modified it where the /* here */ line is.. the $x_body_backup would still be valid.. but not after the $x_doc->append_child($x_html); What you can do is, reverse the order of your appendings.. so that you append the highest level node at the end.. so that your reference is still valid after, or wait till you have filled all of the nodes you wanted to add before you append it to your parent node.

As of version 4.3 PHP doesn't support Appending a child from another source document. If you are trying to import information from multiple sources into a final document [for transformation using XSL as an example] then you can have problems. This technique can be used to do it though. I am assuming you have two documents open, $xmldoc1 and $xmldoc2 and you have selected [via XPath or explicit searching] the nodes you want in each document. Thus $xmldoc1_appending_node is the node you would like to add $xmldoc2_importnode to. <? // first we create a temporary node within the document we want to add to. $temp_importnode = $xmldoc1->create_element("import"); // now we have a node that is in the right document context we can clone the one we want into this one. $temp_importnode = $xmldoc_importnode->clone_node(true); // by using true in the above call to clone_node() we copy all of the child nodes as well. Use false or nothing if you just want the containing node with no children. $xmldoc1_appending->append_child($importnode); ?> Now your document contains the new nodes imported from a different document.
