Returns all text of Text nodes logically-adjacent text nodes to this node, concatenated in document order.

  Returns all text of Text nodes logically-adjacent text
nodes to this node, concatenated in document order.

For instance, in the example below wholeText on the
Text node that contains "bar" returns "barfoo", while on
the Text node that contains "foo" it returns "barfoo".

                     +-----+
                     | <p> |
                     +-----+
                       /\
                      /  \
               /-----\    +-------+
               | bar |    | &ent; |
               \-----/    +-------+
                              |
                              |
                           /-----\
                           | foo |
                           \-----/
 

Figure: barTextNode.wholeText value is "barfoo"

  Returns whether this text node contains element content whitespace, often abusively called "ignorable whitespace".

  Returns whether this text node contains
element content whitespace, often abusively called "ignorable whitespace". The text node is
determined to contain whitespace in element content during the load
of the document or if validation occurs while using
Document.normalizeDocument().

  Replaces the text of the current node and all logically-adjacent text nodes with the specified text.

  Replaces the text of the current node and all logically-adjacent text nodes with the specified text. All logically-adjacent text nodes are removed including the current node unless it was the recipient of the replacement text.

This method returns the node which received the replacement text. The returned node is:

• null, when the replacement text is the empty string;
• the current node, except when the current node is read-only;
• a new Text node of the same type ( Text or CDATASection) as the current node inserted at the location of the replacement.

For instance, in the above example calling replaceWholeText on the Text node that contains "bar" with "yo" in argument results in the following:

                     +-----+
                     | <p> |
                     +-----+
                        |
                        |
                     /-----\
                     | yo  |
                     \-----/
 

Figure: barTextNode.replaceWholeText("yo") modifies the textual content of barTextNode with "yo"

Where the nodes to be removed are read-only descendants of an EntityReference, the EntityReference must be removed instead of the read-only nodes. If any EntityReference to be removed has descendants that are not EntityReference, Text, or CDATASection nodes, the replaceWholeText method must fail before performing any modification of the document, raising a DOMException with the code NO_MODIFICATION_ALLOWED_ERR.

For instance, in the example below calling replaceWholeText on the Text node that contains "bar" fails, because the EntityReference node "ent" contains an Element node which cannot be removed.

Returns: The Text node created with the specified content.
Parameters:
- content - The content of the replacing Text node.
Throws:
- DOMException - NO_MODIFICATION_ALLOWED_ERR: Raised if one of the Text nodes being replaced is readonly.

  Breaks this node into two nodes at the specified offset, keeping both in the tree as siblings.

  Breaks this node into two nodes at the specified offset,
keeping both in the tree as siblings. After being split, this node
will contain all the content up to the offset point. A
new node of the same type, which contains all the content at and
after the offset point, is returned. If the original
node had a parent node, the new node is inserted as the next sibling
of the original node. When the offset is equal to the
length of this node, the new node has no data.
Returns: The new node, of the same type as this node.
Parameters:
- offset - The 16-bit unit offset at which to split, starting from 0.
Throws:
- DOMException - INDEX_SIZE_ERR: Raised if the specified offset is negative or greater than the number of 16-bit units in data.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
