Most of methods have been inspired by org.w3c.dom.traversal.TreeWalker. author:    Jose Maria Arranz Santamaria Method Summary public static  int getChildElementCount(Node node)      Returns the number of child elements of the specified node. public static  Element getFirstChildElement(Node node)      Returns the first direct child org.w3c.dom.Element below the specified node. public static  Element getFirstChildElementWithTag(Node parent, String tagName)      Returns the first direct child element with the specified tag name. Parameters:   parent - the parent node. Parameters:   tagName - the tag name to search for, if an HTML tag use uppercase. public static  Element getLastChildElement(Node node)      Returns the last direct child org.w3c.dom.Element below the specified node. public static  Element getNextElement(Node node)      Returns the next org.w3c.dom.Element following the specified node in document order. public static  Node getNextNode(Node node)      Returns the next node following the specified node in document order. public static  Element getNextSiblingElement(Node node)      Returns the next sibling org.w3c.dom.Element following the specified node. public static  Element getParentElement(Node node)      Returns the first parent org.w3c.dom.Element of specified node. public static  Element getPreviousElement(Node node)      Returns the previous org.w3c.dom.Element following the specified node in document order. public static  Node getPreviousNode(Node node)      Returns the previous node following the specified node in document order. public static  Element getPreviousSiblingElement(Node node)      Returns the previous sibling org.w3c.dom.Element following the specified node. public static  boolean hasChildElements(Node node)      Informs whether the specified node has child elements. Method Detail getChildElementCount public static int getChildElementCount(Node node)(Code) Returns the number of child elements of the specified node. Parameters:   node - the node to inspect. the number of child elements. getFirstChildElement public static Element getFirstChildElement(Node node)(Code) Returns the first direct child org.w3c.dom.Element below the specified node. Any child non-element is ignored. Parameters:   node - the node parent. the first child element. Null if the parent node has no child element. getFirstChildElementWithTag public static Element getFirstChildElementWithTag(Node parent, String tagName)(Code) Returns the first direct child element with the specified tag name. Parameters:   parent - the parent node. Parameters:   tagName - the tag name to search for, if an HTML tag use uppercase. the first direct child element with this tag or null if not found. getLastChildElement public static Element getLastChildElement(Node node)(Code) Returns the last direct child org.w3c.dom.Element below the specified node. Any child non-element is ignored. Parameters:   node - the node parent. the last child element. Null if the parent node has no child element. getNextElement public static Element getNextElement(Node node)(Code) Returns the next org.w3c.dom.Element following the specified node in document order. Any non-element is ignored. Parameters:   node - the original node. the next element. Null if the node has no next element. getNextNode public static Node getNextNode(Node node)(Code) Returns the next node following the specified node in document order. Parameters:   node - the original node. the next node. Null if the node has no next node. getNextSiblingElement public static Element getNextSiblingElement(Node node)(Code) Returns the next sibling org.w3c.dom.Element following the specified node. Any non-element is ignored. Parameters:   node - the original node. the next sibling element. Null if the node has no next sibling element (last child element). getParentElement public static Element getParentElement(Node node)(Code) Returns the first parent org.w3c.dom.Element of specified node. Any non-element parent is ignored. Parameters:   node - the original node. the first parent element. Null if the node has no parent element (for instance, the document root element). getPreviousElement public static Element getPreviousElement(Node node)(Code) Returns the previous org.w3c.dom.Element following the specified node in document order. Any non-element is ignored. Parameters:   node - the original node. the previous element. Null if the node has no previous element. getPreviousNode public static Node getPreviousNode(Node node)(Code) Returns the previous node following the specified node in document order. Parameters:   node - the original node. the previous node. Null if the node has no previous node. getPreviousSiblingElement public static Element getPreviousSiblingElement(Node node)(Code) Returns the previous sibling org.w3c.dom.Element following the specified node. Any non-element is ignored. Parameters:   node - the original node. the previous sibling element. Null if the node has no previous sibling element (first child element). hasChildElements public static boolean hasChildElements(Node node)(Code) Informs whether the specified node has child elements. Parameters:   node - the node to inspect. true if the specified node has child elements.
