Interface Text
- All Known Subinterfaces:
- CDATASection
- public interface Text
- extends CharacterData
The Text
interface 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
a list of elements 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 Element
merges any such adjacent Text
objects into a single node for each block of text; this is
recommended before employing operations that depend on a particular
document structure, such as navigation with XPointers.

splitText
public Text splitText(int offset)
throws DOMException
Breaks this Text
node into two Text nodes at the
specified offset, keeping both in the tree as siblings. This node then
only contains all the content up to the offset
point. And
a new Text
node, which is inserted as the next sibling of
this node, contains all the content at and after the
offset
point.
- Parameters:
offset
- The offset at which to split, starting from 0.- Returns:
- The new
Text
node. - Throws:
- INDEX_SIZE_ERR: - Raised if the specified offset is negative or
greater than the number of characters in
data
.NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
