<hr><a name="_details"></a><h2>Detailed Description</h2>
Interface for an element's attribute specifications.
<p>
The SAX parser implements this interface and passes an instance to the SAX application as the second argument of each startElement event.<p>
The instance provided will return valid results only during the scope of the startElement invocation (to save it for future use, the application must make a copy: the AttributeListImpl helper class provides a convenient constructor for doing so).<p>
An <a class="el" href="classAttributeList.html" title="Interface for an element&#39;s attribute specifications.">AttributeList</a> includes only attributes that have been specified or defaulted: IMPLIED attributes will not be included.<p>
There are two ways for the SAX application to obtain information from the <a class="el" href="classAttributeList.html" title="Interface for an element&#39;s attribute specifications.">AttributeList</a>. First, it can iterate through the entire list:<p>
<code> public void startElement (String name, <a class="el" href="classAttributeList.html" title="Interface for an element&#39;s attribute specifications.">AttributeList</a> atts) {<br>
&nbsp;for (int i = 0; i &lt; atts.getLength(); i++) {<br>
&nbsp;&nbsp;String name = atts.getName(i);<br>
&nbsp;&nbsp;String type = atts.getType(i);<br>
&nbsp;&nbsp;String value = atts.getValue(i);<br>
&nbsp;&nbsp;[...]<br>
&nbsp;}<br>
} </code><p>
(Note that the result of <a class="el" href="classAttributeList.html#ddc265faf59d1130454c6cd89d8b0062" title="Return the number of attributes in this list.">getLength()</a> will be zero if there are no attributes.)<p>
As an alternative, the application can request the value or type of specific attributes:<p>
<code> public void startElement (String name, <a class="el" href="classAttributeList.html" title="Interface for an element&#39;s attribute specifications.">AttributeList</a> atts) {<br>
&nbsp;String identifier = atts.getValue("id");<br>
&nbsp;String label = atts.getValue("label");<br>
&nbsp;[...]<br>
} </code><p>
The AttributeListImpl helper class provides a convenience implementation for use by parser or application writers.<p>

Return the type of an attribute in the list (by position).
<p>
The attribute type is one of the strings "CDATA", "ID", "IDREF", "IDREFS", "NMTOKEN", "NMTOKENS", "ENTITY", "ENTITIES", or "NOTATION" (always in upper case).<p>
If the parser has not read a declaration for the attribute, or if the parser does not report attribute types, then it must return the value "CDATA" as stated in the XML 1.0 Recommentation (clause 3.3.3, "Attribute-Value Normalization").<p>
For an enumerated attribute that is not a notation, the parser will report the type as "NMTOKEN".<p>
