Method Detail

getAttributeValue

public static String getAttributeValue(Element parent,
                                       String attribute)

Helper method, that returns the attribute value or null, if the attribute is not defined. DOM method getAttribute will return an empty string, if the attribute node does not exist, which is not desirable in some cases.

findFirstChild

public static Element findFirstChild(Node parent,
                                     String name)

Finds the first direct child element named "name" under the specified parent. The method ignores XML namespaces.

Parameters:

parent - The parent to search in

name - The tag name to search for

Returns:

The Element or null, if there's no such child.

getChildren

public static List<Element> getChildren(Element parent,
                                        String tagName)

Builds a list of direct child Nodes of an Element with the specified tag name. This method does not respect XML namespaces. Note that the DOM method getElementsByTagName returns all descendants that use the specified tag, not just direct children.
