If there is no markup inside an element's content, the text is contained in a single object implementing the [DOMText](classDOMText.html "The DOMText interface inherits from DOMCharacterData and represents the textual content (termed chara...") interface that is the only child of the element. If there is markup, it is parsed into the information items (elements, comments, etc.) and [DOMText](classDOMText.html "The DOMText interface inherits from DOMCharacterData and represents the textual content (termed chara...") nodes that form the list of children of the element.

When a document is first made available via the DOM, there is only one [DOMText](classDOMText.html "The DOMText interface inherits from DOMCharacterData and represents the textual content (termed chara...") node for each block of text. Users may create adjacent [DOMText](classDOMText.html "The DOMText interface inherits from DOMCharacterData and represents the textual content (termed chara...") nodes that represent the contents of a given element without any intervening markup, but should be aware that there is no way to represent the separations between these nodes in XML or HTML, so they will not (in general) persist between DOM editing sessions. The [normalize()](classDOMNode.html#af97e7de1b1765dd48b537600dad41b35 "Puts all DOMText nodes in the full depth of the sub-tree underneath this DOMNode, including attribute...") method on [DOMNode](classDOMNode.html "The DOMNode interface is the primary datatype for the entire Document Object Model.") merges any such adjacent [DOMText](classDOMText.html "The DOMText interface inherits from DOMCharacterData and represents the textual content (termed chara...") objects into a single node for each block of text.

◆ DOMText() [1/2]

◆ DOMText() [2/2]

Destructor.

◆ getIsElementContentWhitespace()

Returns whether this text node contains element content whitespace, often abusively called "ignorable whitespace".

The text node is determined to contain whitespace in element content during the load of the document or if validation occurs while using [DOMDocument::normalizeDocument()](classDOMDocument.html#a885bc5e1454842a82d22f75c35c25ff7 "This method acts as if the document was going through a save and load cycle, putting the document in ...").

Since

DOM Level 3

◆ getWholeText()

Returns all text of [DOMText](classDOMText.html "The DOMText interface inherits from DOMCharacterData and represents the textual content (termed chara...") nodes logically-adjacent text nodes to this node, concatenated in document order.

Since

DOM Level 3

◆ isIgnorableWhitespace()

Non-standard extension.

Return true if this node contains ignorable whitespaces only.

Returns

True if this node contains ignorable whitespaces only.

◆ replaceWholeText()

Substitutes the a specified text for the text of the current node and all logically-adjacent text nodes.

This method returns the node in the hierarchy which received the replacement text, which is null if the text was empty or is the current node if the current node is not read-only or otherwise is a new node of the same type as the current node inserted at the site of the replacement. All logically-adjacent text nodes are removed including the current node unless it was the recipient of the replacement text.
Where the nodes to be removed are read-only descendants of an [DOMEntityReference](classDOMEntityReference.html "DOMEntityReference objects may be inserted into the structure model when an entity reference is in th..."), the [DOMEntityReference](classDOMEntityReference.html "DOMEntityReference objects may be inserted into the structure model when an entity reference is in th...") must be removed instead of the read-only nodes. If any [DOMEntityReference](classDOMEntityReference.html "DOMEntityReference objects may be inserted into the structure model when an entity reference is in th...") to be removed has descendants that are not [DOMEntityReference](classDOMEntityReference.html "DOMEntityReference objects may be inserted into the structure model when an entity reference is in th..."), [DOMText](classDOMText.html "The DOMText interface inherits from DOMCharacterData and represents the textual content (termed chara..."), or [DOMCDATASection](classDOMCDATASection.html "CDATA sections are used to escape blocks of text containing characters that would otherwise be regard...") nodes, the replaceWholeText method must fail before performing any modification of the document, raising a [DOMException](classDOMException.html) with the code NO_MODIFICATION_ALLOWED_ERR.

Parameters

Returns

The [DOMText](classDOMText.html "The DOMText interface inherits from DOMCharacterData and represents the textual content (termed chara...") node created with the specified content.

Exceptions

Since

DOM Level 3

◆ splitText()

Breaks this node into two nodes at the specified offset, keeping both in the tree as siblings.

After being split, this node will contain all the content up to the offset point. A new node of the same type, which contains all the content at and after the offset point, is returned. If the original node had a parent node, the new node is inserted as the next sibling of the original node. When the offset is equal to the length of this node, the new node has no data.

Parameters

Returns

The new node, of the same type as this node.

Exceptions

Since

DOM Level 1
