Method Detail

extractMultipleChildren

public static List<String> extractMultipleChildren(Node parent,
                                                   String elementName)

extractOneChildText

public static String extractOneChildText(Node parent,
                                         String elementName)

extractOneChild

public static Node extractOneChild(Node parent,
                                   String elementName)

extractTagData

public static Collection<String> extractTagData(Document doc,
                                                String tag)

Parameters:

doc - - the xml document to search through

tag - -the name of the element we are looking for

Returns:

a collection of strings that represent all the data contained within the given tag (for each instance of that tag)

getTextValue

public static String getTextValue(Element ele)

Make the horrible DOM API slightly more bearable: get the text value we know this element contains. Borrowed from the Spring API. Using Node.getTextContent() to fix failing tests, if there is a problem, see history before Feb 22. 2018 Also, this is the previous note (related to the code I removed): * Note that we can't really use the alternative Node.getTextContent() because it isn't supported by older Xerces * implementations (1.x), which tend to leak into the classloader. Causes recurring problems with tests.

Parameters:

ele - element

Returns:

text value

openAndParse

                             throws IOException,
