<p>If there is no markup inside an element's content, the text is contained in a single object implementing the <code><aclass="el"href="classxercesc_1_1DOMText.html"title="The DOMText interface inherits from DOMCharacterData and represents the textual content...">DOMText</a></code> interface that is the only child of the element. If there is markup, it is parsed into the information items (elements, comments, etc.) and <code><aclass="el"href="classxercesc_1_1DOMText.html"title="The DOMText interface inherits from DOMCharacterData and represents the textual content...">DOMText</a></code> nodes that form the list of children of the element. </p>

Users may create adjacent <code><aclass="el"href="classxercesc_1_1DOMText.html"title="The DOMText interface inherits from DOMCharacterData and represents the textual content...">DOMText</a></code> 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.

<p>Returns whether this text node contains element content whitespace, often abusively called "ignorable whitespace". </p>
<p>The text node is determined to contain whitespace in element content during the load of the document or if validation occurs while using <code><aclass="el"href="classxercesc_1_1DOMDocument.html#ac4a3e3ffb33ce907f211d216b356f8fb"title="This method acts as if the document was going through a save and load cycle, putting...">DOMDocument::normalizeDocument()</a></code>.</p>
<p>Returns all text of <code><aclass="el"href="classxercesc_1_1DOMText.html"title="The DOMText interface inherits from DOMCharacterData and represents the textual content...">DOMText</a></code> nodes logically-adjacent text nodes to this node, concatenated in document order. </p>
<p>Substitutes the a specified text for the text of the current node and all logically-adjacent text nodes. </p>
<p><br/>
This method returns the node in the hierarchy which received the replacement text, which is null if the text was empty or is the current node if the current node is not read-only or otherwise is a new node of the same type as the current node inserted at the site of the replacement. All logically-adjacent text nodes are removed including the current node unless it was the recipient of the replacement text. <br/>
Where the nodes to be removed are read-only descendants of an <code><aclass="el"href="classxercesc_1_1DOMEntityReference.html"title="DOMEntityReference objects may be inserted into the structure model when an entity...">DOMEntityReference</a></code>, the <code><aclass="el"href="classxercesc_1_1DOMEntityReference.html"title="DOMEntityReference objects may be inserted into the structure model when an entity...">DOMEntityReference</a></code> must be removed instead of the read-only nodes.

<p>Breaks this node into two nodes at the specified <code>offset</code>, keeping both in the tree as siblings. </p>
<p>After being split, this node will contain all the content up to the <code>offset</code> point. A new node of the same type, which contains all the content at and after the <code>offset</code> point, is returned.
