Method Detail

convert

public static XMLNode convert(Node n)

isElementPath

public static boolean isElementPath(XMLNode root,
                    String path)

Returns true if the path exists in the document, otherwise false

getPathString

public static String getPathString(XMLNode e)

Returns a string describing the current location in the DOM

getElementContent

public static String getElementContent(XMLNode root,
                       String path)

Like getElementContents(...) but with a defaultValue of null

getMultiElementContent

public static String[] getMultiElementContent(XMLNode root,
                              String path)

Like getElementContents(...) but with a defaultValue of null

getElementContent

public static String getElementContent(XMLNode root,
                       String path,
                       String defaultvalue)

Returns the value of the last element tag in the path, e.g., <..>value. The DOM is assumes to be normalized. If no value is found, the defaultvalue is returned

findElementPath

public static XMLNode findElementPath(XMLNode elem,
                      String path)

Parses a path string of the form and returns the specific Element node for that tag, or null if it does not exist. If multiple elements exists with same path the first is returned

findChildElement

public static XMLNode findChildElement(XMLNode elem,
                       String tag)

Returns an child element with the current tag name or null.

visitElements

public static void visitElements(XMLNode root,
                 String path,
                 XMLParsing.ElementVisitor ev)

Visits all elements which matches the . The iteration is only done on the last elment in the path.

visitChildrenElements

public static void visitChildrenElements(XMLNode elem,
                         XMLParsing.ElementVisitor ev)
