    • hasChildNodes

      public boolean hasChildNodes()
      This is a convenience method to allow easy determination of whether a node has any children.

      hasChildNodes in interface Node
      Returns:
      true if the node has any children, false if the node has no children.

    • cloneNode

      public Node cloneNode(boolean deep)

      Cloning an Element copies all attributes and their values, including those generated by the XML processor to represent defaulted attributes, but this method does not copy any text it contains unless it is a deep clone, since the text is contained in a child Text node. Cloning any other type of node simply returns a copy of this node.
      Specified by:
      cloneNode in interface Node
      Parameters:
      deep - If true, recursively clone the subtree under the specified node; if false, clone only the node itself (and its attributes, if it is an Element).
      Returns:
      The duplicate node.

    • isEqualNode

      public boolean isEqualNode(Node arg)
      Tests whether two nodes are equal.
      This method tests for equality of nodes, not sameness (i.e., whether the two nodes are references to the same object) which can be tested with Node.isSameNode(). All nodes that are the same will also be equal, though the reverse may not be true.
      Two nodes are equal if and only if the following conditions are satisfied:
      • The two nodes are of the same type.
      • The following string attributes are equal: nodeName, localName, namespaceURI, prefix, nodeValue . This is: they are both null, or they have the same length and are character for character identical.
      • The attributes NamedNodeMaps are equal. This is: they are both null, or they have the same length and for each node that exists in one map there is a node that exists in the other map and is equal, although not necessarily at the same index.
      • The childNodes NodeLists are equal. This is: they are both null, or they have the same length and contain equal nodes at the same index. Note that normalization can affect equality; to avoid this, nodes should be normalized before being compared.

      For two DocumentType nodes to be equal, the following conditions must also be satisfied:
      • The following string attributes are equal: publicId, systemId, internalSubset.
      • The entities NamedNodeMaps are equal.
      • The notations NamedNodeMaps are equal.

      On the other hand, the following do not affect equality: the ownerDocument, baseURI, and parentNode attributes, the specified attribute for Attr nodes, the schemaTypeInfo attribute for Attr and Element nodes, the Text.isElementContentWhitespace attribute for Text nodes, as well as any user data or event listeners registered on the nodes.

      Note: As a general rule, anything not mentioned in the description above is not significant in consideration of equality checking. Note that future versions of this specification may take into account more attributes and implementations conform to this specification are expected to be updated accordingly.

      Specified by:
      isEqualNode in interface Node
      Parameters:
      arg - The node to compare equality with.
      Returns:
      Returns true if the nodes are equal, false otherwise.
      Since:
      DOM Level 3

    • isSameNode

      public boolean isSameNode(Node other)
      Returns whether this node is the same node as the given one.
      This method provides a way to determine whether two Node references returned by the implementation reference the same object. When two Node references are references to the same object, even if through a proxy, the references may be used completely interchangeably, such that all attributes have the same values and calling the same DOM method on either reference always has exactly the same effect.
      Specified by:
      isSameNode in interface Node
      Parameters:
      other - The node to test against.
      Returns:
      Returns true if the nodes are the same, false otherwise.
      Since:
      DOM Level 3

    • setTextContent

      public void setTextContent(String textContent) throws DOMException
      This attribute returns the text content of this node and its descendants. When it is defined to be null, setting it has no effect. On setting, any possible children this node may have are removed and, if it the new string is not empty or null, replaced by a single Text node containing the string this attribute is set to.
      On getting, no serialization is performed, the returned string does not contain any markup. No whitespace normalization is performed and the returned string does not contain the white spaces in element content (see the attribute Text.isElementContentWhitespace). Similarly, on setting, no parsing is performed either, the input string is taken as pure textual content.
      The string returned is made of the text content of this node depending on its type, as defined below:
      Node type Content
      ELEMENT_NODE, ATTRIBUTE_NODE, ENTITY_NODE, ENTITY_REFERENCE_NODE, DOCUMENT_FRAGMENT_NODE concatenation of the textContent attribute value of every child node, excluding COMMENT_NODE and PROCESSING_INSTRUCTION_NODE nodes. This is the empty string if the node has no children.
      TEXT_NODE, CDATA_SECTION_NODE, COMMENT_NODE, PROCESSING_INSTRUCTION_NODE nodeValue
      DOCUMENT_NODE, DOCUMENT_TYPE_NODE, NOTATION_NODE null
      Specified by:
      setTextContent in interface Node

      The string returned is made of the text content of this node depending on its type, as defined below:
      Node type Content
      ELEMENT_NODE, ATTRIBUTE_NODE, ENTITY_NODE, ENTITY_REFERENCE_NODE, DOCUMENT_FRAGMENT_NODE concatenation of the textContent attribute value of every child node, excluding COMMENT_NODE and PROCESSING_INSTRUCTION_NODE nodes. This is the empty string if the node has no children.
      TEXT_NODE, CDATA_SECTION_NODE, COMMENT_NODE, PROCESSING_INSTRUCTION_NODE nodeValue
      DOCUMENT_NODE, DOCUMENT_TYPE_NODE, NOTATION_NODE null
      Specified by:

      DOM Level 3

    • getBaseURI

      public String getBaseURI()
      The absolute base URI of this node or null if the implementation wasn't able to obtain an absolute URI. This value is computed as described in . However, when the Document supports the feature "HTML" [DOM Level 2 HTML] , the base URI is computed using first the value of the href attribute of the HTML BASE element if any, and the value of the documentURI attribute from the Document interface otherwise.

    • getFeature

      public Object getFeature(String feature, String version)
      This method returns a specialized object which implements the specialized APIs of the specified feature and version, as specified in . The specialized object may also be obtained by using binding-specific casting methods but is not necessarily expected to, as discussed in . This method also allow the implementation to provide specialized objects which do not support the Node interface.
      Specified by:
      getFeature in interface Node
      Parameters:
      feature - The name of the feature requested. Note that any plus sign "+" prepended to the name of the feature will be ignored since it is not significant in the context of this method.
      version - This is the version number of the feature to test.
      Returns:
      Returns an object which implements the specialized APIs of the specified feature and version, if any, or null if there is no object which implements interfaces associated with that feature. If the DOMObject returned by this method implements the Node interface, it must delegate to the primary core Node and not return results inconsistent with the primary core Node such as attributes, childNodes, etc.
