Documentation

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, 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.

Constructors and assignment operator

DOM_Text()
Default constructor for DOM_Text. The resulting object does not refer to an actual Text node; it will compare == to 0, and is similar to a null object reference variable in Java. It may subsequently be assigned to refer to an actual comment node.

DOM_Text(const DOM_Text &other)
Copy constructor. Creates a new DOM_Text that refers to the same underlying node as the original. See also DOM_Node::clone(), which will copy the actual Text node, rather than just creating a new reference to the original node.
Parameters:
other - The object to be copied.

DOM_Text& operator = (const DOM_Text &other)
Assignment operator.
Parameters:
other - The object to be copied.

DOM_Text& operator = (const DOM_NullPtr *val)
Assignment operator. This overloaded variant is provided for the sole purpose of setting a DOM_Node reference variable to zero. Nulling out a reference variable in this way will decrement the reference count on the underlying Node object that the variable formerly referenced. This effect is normally obtained when reference variable goes out of scope, but zeroing them can be useful for global instances, or for local instances that will remain in scope for an extended time, when the storage belonging to the underlying node needs to be reclaimed.
Parameters:
val. - Only a value of 0, or null, is allowed.

Destructor.

~DOM_Text()
Destructor for DOM_Text. The object being destroyed is the reference object, not the underlying Comment node itself.

Functions to modify the Text node.

DOM_Text splitText(int 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.
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.
Returns:
The new Text node.
Parameters:
offset - The offset at which to split, starting from 0.
