<DT>public interface <B>Attributes</B>
</DL>
<DL><DD>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> </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).</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 <A HREF="org.xml.sax.AttributeList AttributeList">AttributeList</A> 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><DL><DD></DD></DL></DD>
