  - getAttributes
```
public static List getAttributes(Element el)
```
    Returns a list of attributes of an element. Returns an empty list if the element has no attributes. Does not include namespace declarations.
    
    Parameters:
    el - Element whose attributes are returned
    
    Returns:
    the List of Attr
  - getAttribute
```
public static String getAttribute(Element el,
                  String attrName)
```
    Returns the value of an attribute of an element. Returns null if the attribute is not found (whereas Element.getAttribute returns "" if an attrib is not found). This method should be used for elements that support extension attributes because it does not track unexpected attributes.
    
    Parameters:
    el - Element whose attrib is looked for
    attrName - name of attribute to look for
    
    Returns:
    the attribute value including prefix if present
  - getAttribute
```
public static String getAttribute(Element el,
                  String attrName,
                  List remainingAttrs)
```
    Returns the value of an attribute of an element. Returns null if the attribute is not found (whereas Element.getAttribute returns "" if an attrib is not found). This method should be used for elements that do not support extension attributes because it tracks the element's remaining attributes so that eventually any unexpected attributes can be identified.
    
    Parameters:
    el - Element whose attrib is looked for
    attrName - name of attribute to look for
    remainingAttrs - List of remaining attributes
    
    Returns:
    the attribute value
  - getAttributeNS
```
public static String getAttributeNS(Element el,
                    String namespaceURI,
                    String localPart)
```
    Returns the value of an attribute of an element. Returns null if the attribute is not found (whereas Element.getAttributeNS returns "" if an attrib is not found).
    
    Parameters:
    el - Element whose attrib is looked for
    namespaceURI - namespace URI of attribute to look for
    localPart - local part of attribute to look for
    
    Returns:
    the attribute value
  - getChildCharacterData
```
public static String getChildCharacterData(Element parentEl)
```
    Concat all the text and cdata node children of this elem and return the resulting text.
    
    Parameters:
    parentEl - the element whose cdata/text node values are to be combined.
    
    Returns:
    the concatanated string.
  - getFirstChildElement
```
public static Element getFirstChildElement(Element elem)
```
    Return the first child element of the given element. Null if no children are found.
    
    Parameters:
    elem - Element whose child is to be returned
    
    Returns:
    the first child element.
  - getNextSiblingElement
```
public static Element getNextSiblingElement(Element elem)
```
    Return the next sibling element of the given element. Null if no more sibling elements are found.
    
    Parameters:
    elem - Element whose sibling element is to be returned
    
    Returns:
    the next sibling element.
  - findChildElementWithAttribute
```
public static Element findChildElementWithAttribute(Element elem,
                                    String attrName,
                                    String attrValue)
```
    Return the first child element of the given element which has the given attribute with the given value.
    
    Parameters:
    elem - the element whose children are to be searched
    attrName - the attrib that must be present
    attrValue - the desired value of the attribute
    
    Returns:
    the first matching child element.
  - countKids
```
public static int countKids(Element elem,
            short nodeType)
```
    Count number of children of a certain type of the given element.
    
    Parameters:
    elem - the element whose kids are to be counted
    
    Returns:
    the number of matching kids.
  - throwWSDLException

```
    Prints attributes with qualified names.
    
    Throws:
    
    WSDLException
