Interface Text
- All Known Subinterfaces:
- CDATASection
- public interface Text
- extends CharacterData
The Text
interface inherits from CharacterData
and
represents the textual content (termed character data in XML) of an
Element
or Attr
. If there is no markup inside an
element's content, the text is contained in a single object implementing the
Text
interface that is the only child of the element. If there is
markup, it is parsed into the information items (elements, comments, etc.) and
Text
nodes 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 normalize()
method on Node
merges any such adjacent Text
objects
into a single node for each block of text.

Model (DOM) Level 2 Core Specification.

splitText
public Text splitText(int offset)
throws DOMException
- 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:
offset
- The 16-bit unit offset at which to split, starting
from 0
.
- Returns:
- The new node, of the same type as this node.
- Throws:
- DOMException -
INDEX_SIZE_ERR: Raised if the specified offset is negative or greater than the
number of 16-bit units in
data
.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
