Method Detail

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

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.

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.
