XXV. DOM XML functions

Avertisment

Această extensie este EXPERIMENTALĂ. Comportamentul acestei extensii, incluzând numele funcţiilor şi orice altceva documentat despre această extensie ar putea fi schimbate fară un anunţ prealabil, intr-o viitoare versiune PHP. V-am avertizat, deci folosiţi această extensie pe riscul dv.

This documentation is not finished yet. Don't start to translate it or use it as a programming reference (steinm@php.net).

These functions are only available if PHP was configured with --with-dom=[DIR], using the GNOME xml library. You will need at least libxml-2.2.7 These functions have been added in PHP 4.

The extension allows you to operate on an XML document with the DOM API. It also provides a function xmltree() to turn the complete XML document into a tree of PHP objects. Currently this tree should be considered read-only - you can modify it but this would not make any sense since dumpmem() cannot be applied to it. Therefore, if you want to read an XML file and write a modified version use the add_node(), set_attribute(), etc. and finally dumpmem() functions.

This module defines the following constants:

Tabel 1. XML constants

Constant	Value	Description
XML_ELEMENT_NODE	1	Node is an element
XML_ATTRIBUTE_NODE	2	Node is an attribute
XML_TEXT_NODE	3	Node is a piece of text
XML_CDATA_SECTION_NODE	4
XML_ENTITY_REF_NODE	5
XML_ENTITY_NODE	6	Node is an entity like
XML_PI_NODE	7	Node is a processing instruction
XML_COMMENT_NODE	8	Node is a comment
XML_DOCUMENT_NODE	9	Node is a document
XML_DOCUMENT_TYPE_NODE	10
XML_DOCUMENT_FRAG_NODE	11
XML_NOTATION_NODE	12
XML_GLOBAL_NAMESPACE	1
XML_LOCAL_NAMESPACE	2

Each function in this extension can be used in two ways. In a non-object oriented way by passing the object to apply the function to as a first argument, or in an object oriented way by calling the function as a method of an object. This documentation describes the non-object oriented functions, though you get the object methods by skipping the prefix "domxml_".

This module defines a number of classes, which are listed — including their properties and method — in the following table.

Tabel 2. DomDocument class (methods)

Method name	Function name	Description
root	domxml_root()
children	domxml_children()
add_root	domxml_add_root()
dtd	domxml_intdtd()
dumpmem	domxml()
xpath_init	xpath_init
xpath_new_context	xpath_new_context
xptr_new_context	xptr_new_context

Tabel 3. DomDocument class (attributes)

Name	Type	Description
doc	class DomDocument	The object itself
name	string
url	string
version	string	Version of XML
encoding	string
standalone	long	1 if the file is a standalone version
type	long	One of the constants in table ...
compression	long	1 if the file is compressed
charset	long

Tabel 4. DomNode class (methods)

Name	PHP name	Description
lastchild	domxml_last_child()
children	domxml_children()
parent	domxml_parent()
new_child	domxml_new_child()
get_attribute	domxml_get_attribute()
set_attribute	domxml_set_attribute()
attributes	domxml_attributes()
node	domxml_node()

Tabel 5. DomNode class (attributes)

Name	Type	Description

type	long
tagname	string
content	string
