Method Detail

### getChildElementsByTagName

    public static List getChildElementsByTagName(Element ele,
                                                 String[] childEleNames)

  Retrieve all child elements of the given DOM element that match any of the given element names. Only look at the direct child level of the given element; do not go into further depth (in contrast to the DOM API's `getElementsByTagName` method).

  Parameters:
    `ele` - the DOM element to analyze
    `childEleNames` - the child element names to look for
  Returns:
    a List of child `org.w3c.dom.Element` instances
  See Also:
    `Element`, `Element.getElementsByTagName(java.lang.String)`

### getChildElementsByTagName

    public static List getChildElementsByTagName(Element ele,
                                                 String childEleName)

  Retrieve all child elements of the given DOM element that match the given element name. Only look at the direct child level of the given element; do not go into further depth (in contrast to the DOM API's `getElementsByTagName` method).

  Parameters:
    `ele` - the DOM element to analyze
    `childEleName` - the child element name to look for
  Returns:
    a List of child `org.w3c.dom.Element` instances
  See Also:
    `Element`, `Element.getElementsByTagName(java.lang.String)`

### getChildElementByTagName

    public static Element getChildElementByTagName(Element ele,
                                                   String childEleName)

  Utility method that returns the first child element identified by its name.

  Parameters:
    `ele` - the DOM element to analyze
    `childEleName` - the child element name to look for
  Returns:
    the `org.w3c.dom.Element` instance, or `null` if none found

### getChildElementValueByTagName

    public static String getChildElementValueByTagName(Element ele,
                                                       String childEleName)

  Utility method that returns the first child element value identified by its name.

  Parameters:
    `ele` - the DOM element to analyze
    `childEleName` - the child element name to look for
  Returns:
    the extracted text value, or `null` if no child element found

### getTextValue

    public static String getTextValue(Element valueEle)

  Extract the text value from the given DOM element, ignoring XML comments.

  Appends all CharacterData nodes and EntityReference nodes into a single String value, excluding Comment nodes.

  See Also:
    `CharacterData`, `EntityReference`, `Comment`

### nodeNameEquals

    public static boolean nodeNameEquals(Node node,
                                         String desiredName)

  Namespace-aware equals comparison. Returns `true` if either `Node.getLocalName()` or `Node.getNodeName()` equals `desiredName`, otherwise returns `false`.
