/** |
|
* Interface for a list of XML attributes. |
|
* |
|
* <blockquote> |
|
* <em>This module, both source code and documentation, is in the |
|
* Public Domain, and comes with <strong>NO WARRANTY</strong>.</em> |
|
* See <a href='http://www.saxproject.org'>http://www.saxproject.org</a> |
|
* for further information. |
|
* </blockquote> |
|
* |
|
* <p>This interface allows access to a list of attributes in |
|
* three different ways:</p> |
|
* |
|
* <ol> |
|
* <li>by attribute index;</li> |
|
* <li>by Namespace-qualified name; or</li> |
|
* <li>by qualified (prefixed) name.</li> |
|
* </ol> |
|
* |
|
* <p>The list will not contain attributes that were declared |
|
* #IMPLIED but not specified in the start tag. It will also not |
|
* contain attributes used as Namespace declarations (xmlns*) unless |
|
* the <code>http://xml.org/sax/features/namespace-prefixes</code> |
|
* feature is set to <var>true</var> (it is <var>false</var> by |
|
* default). |
|
* Because SAX2 conforms to the original "Namespaces in XML" |
|
* recommendation, it normally does not |
|
* give namespace declaration attributes a namespace URI. |
|
* </p> |
|
* |
|
* <p>Some SAX2 parsers may support using an optional feature flag |
|
* (<code>http://xml.org/sax/features/xmlns-uris</code>) to request |
|
* that those attributes be given URIs, conforming to a later |
|
* backwards-incompatible revision of that recommendation. (The |
|
* attribute's "local name" will be the prefix, or "xmlns" when |
|
* defining a default element namespace.) For portability, handler |
|
* code should always resolve that conflict, rather than requiring |
|
* parsers that can change the setting of that feature flag. </p> |
|
* |
|
* <p>If the namespace-prefixes feature (see above) is |
|
* <var>false</var>, access by qualified name may not be available; if |
|
* the <code>http://xml.org/sax/features/namespaces</code> feature is |
|
* <var>false</var>, access by Namespace-qualified names may not be |
|
* available.</p> |
|
* |
|
* <p>This interface replaces the now-deprecated SAX1 {@link |
|
* org.xml.sax.AttributeList AttributeList} interface, which does not |
|
* contain Namespace support. In addition to Namespace support, it |
|
* adds the <var>getIndex</var> methods (below).</p> |
|
* |
|
* <p>The order of attributes in the list is unspecified, and will |
|
* vary from implementation to implementation.</p> |
|
* |

* @since SAX 2.0 |
