Interface AttributeList

Interface for an element's attribute specifications.

This module, both source code and documentation, is in the Public Domain, and comes with NO WARRANTY. See http://www.saxproject.org for further information.

This is the original SAX1 interface for reporting an element's attributes. Unlike the new Attributes interface, it does not support Namespace-related information.

When an attribute list is supplied as part of a startElement event, the list will return valid results only during the scope of the event; once the event handler returns control to the parser, the attribute list is invalid. To save a persistent copy of the attribute list, use the SAX1 AttributeListImpl helper class.

An attribute list includes only attributes that have been specified or defaulted: #IMPLIED attributes will not be included.

There are two ways for the SAX application to obtain information from the AttributeList. First, it can iterate through the entire list:

 public void startElement (String name, AttributeList atts) {
   for (int i = 0; i <32atts.getLength(); i++) {
     String name = atts.getName(i);
     String type = atts.getType(i);
     String value = atts.getValue(i);
     [...]
   }
 }
 

(Note that the result of getLength() will be zero if there are no attributes.)

As an alternative, the application can request the value or type of specific attributes:

 public void startElement (String name, AttributeList atts) {
   String identifier = atts.getValue("id");
   String label = atts.getValue("label");
   [...]
 }
 

Attributes interface, which includes Namespace support.

public String getName(int i)

public String getType(String name)

public String getType(int i)

public String getValue(String name)
