Map parseAttributeValuePairTags(Node parentNode)
parse Attribute Value Pair Tags

NodeList avList = parentNode.getChildNodes();
Map map = null;
int numAVPairs = avList.getLength();
if (numAVPairs <= 0) {
 return EMPTY_MAP;
for (int l = 0; l < numAVPairs; l++) {

Boolean parseBoolean(String xmlAttributeValue, Boolean invalidValue)
parse Boolean

if (xmlAttributeValue == null)
 return invalidValue;
if (xmlAttributeValue.equals(Boolean.TRUE.toString())) {
 return Boolean.TRUE;
} else if (xmlAttributeValue.equals(Boolean.FALSE.toString())) {
 return Boolean.FALSE;

...

String[] parseConfigAttr(NamedNodeMap attributes)
parse Config Attr

String key = attributes.getNamedItem("key").getTextContent();
String value = attributes.getNamedItem("value").getTextContent();
return new String[] { key, value };

String parseElementAttributes(Element element)
Aggregates all attributes from the given element, formats then into the proper key="value" XML format and returns them as one String

if (element.hasAttributes() == false) {
 return null;
StringBuffer buffer = new StringBuffer();
NamedNodeMap attributeMap = element.getAttributes();
for (int i = 0; i < attributeMap.getLength(); i++) {
 Node node = attributeMap.item(i);
 if (node.getNodeType() == Node.ATTRIBUTE_NODE) {
...

float parseFloat(Node xmlAttribute, float invalidValue)
parse Float

if (xmlAttribute == null)
 return invalidValue;
return parseFloat(xmlAttribute.getNodeValue(), invalidValue);

float parseFloat(String attributeName, NamedNodeMap map)
Parses the value of the given attribute as a float.

org.w3c.dom.Node attr = map.getNamedItem(attributeName);
try {
 return attr != null ? Float.parseFloat(attr.getTextContent()) : 0f;
} catch (NumberFormatException ex) {
 return 0.0f;

void parseProtoypes(Node module, Node iFace, PrintWriter out, boolean onlyAttributes)
Parse and write an interface with prototypes

String outline = "";
Node child = null;
writeDescription(out, iFace, " ");
String interFaceName = getAttributeValue(iFace, "name");
out.println(" " + interFaceName + " = function () {");
out.println(" //TODO implement constructor logic if needed!");
out.println();
ArrayList<Node> attributes = getNodesByName("Attribute", iFace.getChildNodes());
...

String parseString(final Element parent, final String attrName)
Return the string value of an attribute, or null if the attribute is missing

if (parent.hasAttribute(attrName)) {
 return parent.getAttribute(attrName);
} else {
 return null;
