71Interface for an element's attribute specifications.
72<p>
73The SAX parser implements this interface and passes an instance to the SAX application as the second argument of each startElement event.
74<p>
75The 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).
76<p>
77An AttributeList includes only attributes that have been specified or defaulted: IMPLIED attributes will not be included.
78<p>
79There are two ways for the SAX application to obtain information from the AttributeList. First, it can iterate through the entire list:
80<p>
81<code> public void startElement (String name, AttributeList atts) {<br>
82 &nbsp;for (int i = 0; i &lt; atts.getLength(); i++) {<br>
83 &nbsp;&nbsp;String name = atts.getName(i);<br>
84 &nbsp;&nbsp;String type = atts.getType(i);<br>
85 &nbsp;&nbsp;String value = atts.getValue(i);<br>
86 &nbsp;&nbsp;[...]<br>
87 &nbsp;}<br>
88 } </code>
89<p>
90(Note that the result of <a class="el" href="classAttributeList.html#z419_0">getLength</a>() will be zero if there are no attributes.)
91<p>
92As an alternative, the application can request the value or type of specific attributes:
93<p>
94<code> public void startElement (String name, AttributeList atts) {<br>
95 &nbsp;String identifier = atts.getValue("id");<br>
96 &nbsp;String label = atts.getValue("label");<br>
97 &nbsp;[...]<br>
98 } </code>
99<p>
100The AttributeListImpl helper class provides a convenience implementation for use by parser or application writers.
