Internally PHPTAL represents documents using it's own document object model, a little bit similar to W3C's DOM. However, PHPTAL's API has only few basic methods for DOM manipulation.
PHPTAL_Dom_Element class has following properties and methods:
array childNodes ;Numerically indexed array containing children of the element.
Please don't edit this array directly. Use appendChild(), etc.
PHPTAL does not implement nextSibling, firstChild, etc.
PHPTAL_Dom_Element parentNode ;Parent node (element) of the current element. Use it to traverse tree upwards.
void appendChild($node);Appends node to the element. Node will be removed from its current element and added at the end of this element.
PHPTAL does not manage namespace declarations. Moving nodes between elements in different namespaces will change meaning of the document.
void replaceChild($new_node,
$old_node);Old node will be replaced with new node.
void removeChild($node);Remove node from its parent.
string getAttributeNS($namespace_uri,
$local_name);Returns unescaped (without entities) value of a specific attribute.
$a->getAttributeNS('','href')In XML attributes don't inherit element's namespace, and all XHTML attributes are in the default namespace.
array getAttributeNodes();Returns array of PHPTAL_Dom_Attr objects, which represent all element's attributes. You can modify attributes' values without using setAttributeNodes().
void setAttributeNodes(array $attrs);Replaces all elements attributes with the given ones.
string getLocalName();Returns local name of the element, e.g. <atom:title> has local name title.
string getNamespaceURI();Returns namespace URI of the the element, e.g. <atom:title xmlns="http://www.w3.org/2005/Atom"> has namespace http://www.w3.org/2005/Atom.
XHTML namespace is http://www.w3.org/1999/xhtml.
Text, CDATA and attribute nodes have getValueEscaped() and setValueEscaped() methods which allow reading/setting of their text with entities preserved.
