## NAME
    [XML::DOM::Text](https://www.chedong.com/phpMan.php/perldoc/XML%3A%3ADOM%3A%3AText/markdown) - A piece of XML text in [XML::DOM](https://www.chedong.com/phpMan.php/perldoc/XML%3A%3ADOM/markdown)

## DESCRIPTION
    [XML::DOM::Text](https://www.chedong.com/phpMan.php/perldoc/XML%3A%3ADOM%3A%3AText/markdown) extends [XML::DOM::CharacterData](https://www.chedong.com/phpMan.php/perldoc/XML%3A%3ADOM%3A%3ACharacterData/markdown), which extends [XML::DOM::Node](https://www.chedong.com/phpMan.php/perldoc/XML%3A%3ADOM%3A%3ANode/markdown).

    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.

  METHODS
    splitText (offset)
        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.

        Return Value: The new Text node.

        DOMExceptions:

        *   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.
