```
public String getType(int index)
```
    Return an attribute's type by index.

    getType in interface Attributes
    
    Parameters:
    index - The attribute's index (zero-based).
    
    Returns:
    The attribute's type, "CDATA" if the type is unknown, or null if the index is out of bounds.

```
public String getValue(int index)
```
    Return an attribute's value by index.

    getValue in interface Attributes
    
    Parameters:
    index - The attribute's index (zero-based).

  - getIndex
```
public int getIndex(String uri,
           String localName)
```
    Look up an attribute's index by Namespace name.
    In many cases, it will be more efficient to look up the name once and use the index query methods rather than using the name query methods repeatedly.
    
    Specified by:
    
    getIndex in interface Attributes
    
    Parameters:
    uri - The attribute's Namespace URI, or the empty string if none is available.
    localName - The attribute's local name.
    
    Returns:
    The attribute's index, or -1 if none matches.
    See Also:
    Attributes.getIndex(java.lang.String,java.lang.String)
  - getIndex
```
public int getIndex(String qName)
```
    Look up an attribute's index by qualified (prefixed) name.
    
    Specified by:
    
    getIndex in interface Attributes
    
    Parameters:
    qName - The qualified name.
    
    Returns:
    The attribute's index, or -1 if none matches.

    localName - The local name.
    
    Returns:
    The attribute's type, or null if there is no matching attribute.
    See Also:
