Method Details

getIndex

public int getIndex(String qName)
Look up an attribute's index by qualified (prefixed) name.

Parameters:
qName - The qualified name.

Returns:
The attribute's index, or -1 if none matches.

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.

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.

Returns:
The number of attributes in the list.

Return an attribute's local name.

Parameters:
