Text

Class Overview

The Text interface inherits from CharacterData and 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 the information items (elements, comments, etc.) 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 Node merges any such adjacent Text objects into a single node for each block of text.

[Expand] Inherited Methods
From interface org.w3c.dom.CharacterData abstract void appendData(String arg) Append the string to the end of the character data of the node. abstract void deleteData(int offset, int count) Remove a range of 16-bit units from the node. abstract String getData() Returns the character data of the node that implements this interface. abstract int getLength() The number of 16-bit units that are available through data and the substringData method below. abstract void insertData(int offset, String arg) Insert a string at the specified 16-bit unit offset. abstract void replaceData(int offset, int count, String arg) Replace the characters starting at the specified 16-bit unit offset with the specified string. abstract void setData(String data) Sets the character data of the node that implements this interface. abstract String substringData(int offset, int count) Extracts a range of data from the node.
From interface org.w3c.dom.Node abstract Node appendChild(Node newChild) Adds the node newChild to the end of the list of children of this node. abstract Node cloneNode(boolean deep) Returns a duplicate of this node, i.e., serves as a generic copy constructor for nodes. abstract NamedNodeMap getAttributes() A NamedNodeMap containing the attributes of this node (if it is an Element) or null otherwise. abstract NodeList getChildNodes() A NodeList that contains all children of this node. abstract Node getFirstChild() The first child of this node. abstract Node getLastChild() The last child of this node. abstract String getLocalName() Returns the local part of the qualified name of this node. abstract String getNamespaceURI() The namespace URI of this node, or null if it is unspecified. abstract Node getNextSibling() The node immediately following this node. abstract String getNodeName() The name of this node, depending on its type; see the table above. abstract short getNodeType() A code representing the type of the underlying object, as defined above. abstract String getNodeValue() Returns the value of this node, depending on its type; see the table above. abstract Document getOwnerDocument() The Document object associated with this node. abstract Node getParentNode() The parent of this node. abstract String getPrefix() Returns the namespace prefix of this node, or null if it is unspecified. abstract Node getPreviousSibling() The node immediately preceding this node. abstract boolean hasAttributes() Returns whether this node (if it is an element) has any attributes. abstract boolean hasChildNodes() Returns whether this node has any children. abstract Node insertBefore(Node newChild, Node refChild) Inserts the node newChild before the existing child node refChild. abstract boolean isSupported(String feature, String version) Tests whether the DOM implementation implements a specific feature and that feature is supported by this node. abstract void normalize() Puts all Text nodes in the full depth of the sub-tree underneath this Node, including attribute nodes, into a "normal" form where only structure (e.g., elements, comments, processing instructions, CDATA sections, and entity references) separates Text nodes, i.e., there are neither adjacent Text nodes nor empty Text nodes. abstract Node removeChild(Node oldChild) Removes the child node indicated by oldChild from the list of children, and returns it. abstract Node replaceChild(Node newChild, Node oldChild) Replaces the child node oldChild with newChild in the list of children, and returns the oldChild node. abstract void setNodeValue(String nodeValue) Sets the value of this node, depending on its type; see the table above. abstract void setPrefix(String prefix) Sets the namespace prefix of this node.
