Text class

The Text interface inherits from CharacterData and represents the textual content (termed character data in XML) of an Element or Attr.

Inheritance: Text → CharacterData → Node → EventTarget → DOMObject

The Text type exposes the following members:

Properties

Property	Description
node_type	A code representing the type of the underlying object.
local_name	Returns the local part of the qualified name of this node. For nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE and nodes created with a DOM Level 1 method, such as Document.createElement(), this is always null.
namespace_uri	The namespace URI of this node, or null if it is unspecified.
prefix	The namespace prefix of this node, or null if it is unspecified. When it is defined to be null, setting it has no effect
node_name	The name of this node, depending on its type.
base_uri	The absolute base URI of this node or null if the implementation wasn’t able to obtain an absolute URI.
owner_document	The Document object associated with this node. This is also the Document object used to create new nodes. When this node is a Document or a DocumentType which is not used with any Document yet, this is null.
parent_node	The parent of this node. All nodes, except Attr, Document, DocumentFragment, Entity, and Notation may have a parent. However, if a node has just been created and not yet added to the tree, or if it has been removed from the tree, this is null.
parent_element	Gets the parent `Element` of this node.
child_nodes	A NodeList that contains all children of this node. If there are no children, this is a NodeList containing no nodes..
first_child	The first child of this node. If there is no such node, this returns null.
last_child	The last child of this node. If there is no such node, this returns null.
previous_sibling	The node immediately preceding this node. If there is no such node, this returns null.
next_sibling	The node immediately following this node. If there is no such node, this returns null.
node_value	The value of this node, depending on its type.
text_content	This attribute returns the text content of this node and its descendants. When it is defined to be null, setting it has no effect. On setting, any possible children this node may have are removed and, if it the new string is not empty or null, replaced by a single Text node containing the string this attribute is set to.
ELEMENT_NODE	An element node
ATTRIBUTE_NODE	An attribute node
TEXT_NODE	A text node
CDATA_SECTION_NODE	A cdata section node
ENTITY_REFERENCE_NODE	An entity reference node
ENTITY_NODE	An entity node
PROCESSING_INSTRUCTION_NODE	A processing instruction node
COMMENT_NODE	A comment node
DOCUMENT_NODE	A document node
DOCUMENT_TYPE_NODE	A document type node
DOCUMENT_FRAGMENT_NODE	A document fragment node
NOTATION_NODE	A notation node
data	The character data of the node that implements this interface.
length	The number of 16-bit units that are available through data and the substringData method below. This may have the value zero, i.e., CharacterData nodes may be empty.
is_element_content_whitespace	Returns whether this text node contains element content whitespace, often abusively called “ignorable whitespace”.
whole_text	Returns all text of Text nodes logically-adjacent text nodes to this node, concatenated in document order.

Methods

Method	Description
add_event_listener	This method allows the registration of event listeners on the event target.
add_event_listener	This method allows the registration of event listeners on the event target.
remove_event_listener	This method allows the removal of event listeners from the event target. If an `IEventListener` is removed from an `EventTarget` while it is processing an event, it will not be triggered by the current actions. Event Listeners can never be invoked after being removed.
remove_event_listener	This method allows the removal of event listeners from the event target. If an `IEventListener` is removed from an `EventTarget` while it is processing an event, it will not be triggered by the current actions. Event Listeners can never be invoked after being removed.
clone_node	Returns a duplicate of this node, i.e., serves as a generic copy constructor for nodes. The duplicate node has no parent (parentNode is null) and no user data.
clone_node	Returns a duplicate of this node, i.e., serves as a generic copy constructor for nodes. The duplicate node has no parent (parentNode is null) and no user data.
get_platform_type	This method is used to retrieve ECMAScript object Type.
dispatch_event	This method allows the dispatch of events into the implementations event model.
has_child_nodes	Returns whether this node has any children.
normalize	Puts all Text nodes in the full depth of the sub-tree underneath this Node, including attribute nodes, into a “normal” form where only structure (e.g., elements, comments, processing instructions, CDATA sections, and entity references) separates Text nodes, i.e., there are neither adjacent Text nodes nor empty Text nodes. This can be used to ensure that the DOM view of a document is the same as if it were saved and re-loaded, and is useful when operations (such as XPointer [XPointer] lookups) that depend on a particular document tree structure are to be used. If the parameter “normalize-characters” of the DOMConfiguration object attached to the Node.ownerDocument is true, this method will also fully normalize the characters of the Text nodes.
is_equal_node	Tests whether two nodes are equal. This method tests for equality of nodes, not sameness (i.e., whether the two nodes are references to the same object) which can be tested with Node.isSameNode(). All nodes that are the same will also be equal, though the reverse may not be true.
is_same_node	Returns whether this node is the same node as the given one. This method provides a way to determine whether two Node references returned by the implementation reference the same object. When two Node references are references to the same object, even if through a proxy, the references may be used completely interchangeably, such that all attributes have the same values and calling the same DOM method on either reference always has exactly the same effect.
lookup_prefix	Look up the prefix associated to the given namespace URI, starting from this node. The default namespace declarations are ignored by this method. See Namespace Prefix Lookup for details on the algorithm used by this method.
lookup_namespace_uri	Look up the namespace URI associated to the given prefix, starting from this node.
is_default_namespace	This method checks if the specified namespaceURI is the default namespace or not.
insert_before	Inserts the node before the existing child node child. If child is null, insert node at the end of the list of children. If child is a DocumentFragment object, all of its children are inserted, in the same order, before child. If the child is already in the tree, it is first removed.
replace_child	Replaces the child node oldChild with newChild in the list of children, and returns the oldChild node. If newChild is a DocumentFragment object, oldChild is replaced by all of the DocumentFragment children, which are inserted in the same order. If the newChild is already in the tree, it is first removed.
remove_child	Removes the child node indicated by oldChild from the list of children, and returns it.
append_child	Adds the node newChild to the end of the list of children of this node. If the newChild is already in the tree, it is first removed.
substring_data	Extracts a range of data from the node.
append_data	Append the string to the end of the character data of the node.
insert_data	Insert a string at the specified 16-bit unit offset.
delete_data	Remove a range of 16-bit units from the node.
replace_data	Replace the characters starting at the specified 16-bit unit offset with the specified string.
split_text	Breaks this node into two nodes at the specified offset, keeping both in the tree as siblings.
replace_whole_text	Replaces the text of the current node and all logically-adjacent text nodes with the specified text. All logically-adjacent text nodes are removed including the current node unless it was the recipient of the replacement text.
