Interface Text
- All Known Subinterfaces:
- CDATASection
- All Known Implementing Classes:
- TextImpl
- public abstract 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:
- DOMException - 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.
