public interface Text extends CharacterData
Textinterface inherits from
CharacterDataand represents the textual content (termed character data in XML) of an
Attr. If there is no markup inside an element's content, the text is contained in a single object implementing the
Textinterface that is the only child of the element. If there is markup, it is parsed into the information items (elements, comments, etc.) and
Textnodes that form the list of children of the element.
When a document is first made available via the DOM, there is only one
Text node for each block of text. Users may create adjacent
Text 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
Node.normalize() method merges any such adjacent
Text objects into a single node for each block of text.
No lexical check is done on the content of a
and, depending on its position in the document, some characters must be
escaped during serialization using character references; e.g. the
characters "<&" if the textual content is part of an element or of
an attribute, the character sequence "]]>" when part of an element,
the quotation mark character " or the apostrophe character ' when part of

Text splitText(int offset) throws DOMException
offset, keeping both in the tree as siblings. After being split, this node will contain all the content up to the
offsetpoint. A new node of the same type, which contains all the content at and after the
offsetpoint, 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
offsetis equal to the length of this node, the new node has no data.
offset- The 16-bit unit offset at which to split, starting from
DOMException- INDEX_SIZE_ERR: Raised if the specified offset is negative or greater than the number of 16-bit units in
Textnodes logically-adjacent text nodes to this node, concatenated in document order.
Textnode that contains "bar" returns "barfoo", while on the
Textnode that contains "foo" it returns "barfoo".
+-----+ | <p> | +-----+ /\ / \ /-----\ +-------+ | bar | | &ent; | \-----/ +-------+ | | /-----\ | foo | \-----/Figure: barTextNode.wholeText value is "barfoo"
Text replaceWholeText(String content) throws DOMException
This method returns the node which received the replacement text. The returned node is:
null, when the replacement text is the empty string;
Textnode of the same type (
CDATASection) as the current node inserted at the location of the replacement.
For instance, in the above example calling
replaceWholeText on the
Text node that
contains "bar" with "yo" in argument results in the following:
+-----+ | <p> | +-----+ | | /-----\ | yo | \-----/Figure: barTextNode.replaceWholeText("yo") modifies the textual content of barTextNode with "yo"
Where the nodes to be removed are read-only descendants of an
be removed instead of the read-only nodes. If any
EntityReference to be removed has descendants that are
CDATASection nodes, the
method must fail before performing any modification of the document,
DOMException with the code
For instance, in the example below calling
replaceWholeText on the
Text node that
contains "bar" fails, because the
"ent" contains an
Element node which cannot be removed.
content- The content of the replacing
Textnode created with the specified content.
DOMException- NO_MODIFICATION_ALLOWED_ERR: Raised if one of the
Textnodes being replaced is readonly.
