NAME¶
XML::DOM::Text - A piece of XML text in XML::DOM
DESCRIPTION¶
XML::DOM::Text extends XML::DOM::CharacterData, which extends XML::DOM::Node.
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.
