public final class AttributeList extends Object implements DTDConstants, Serializable
Stores the attribute information, obtained by parsing SGML (DTD) tag
<!ATTLIST .. >
Elements can have a associated named properties (attributes) having the assigned values. The element start tag can have any number of attribute value pairs, separated by spaces. They can appear in any order. SGML requires you to delimit the attribute values using either double (") or single (') quotation marks. In HTML, it is possible (but not recommended) to specify the value of an attribute without quotation marks. Such attribute value may only contain letters, digits, hyphens (-) and periods (.) .
The AttributeList
defines a single attribute that additionally
has a pointer referencing the possible subsequent attribute.
The whole structure is just a simple linked list, storing all attributes of
some Element
.
Use the getNext()
method repeatedly to see all attributes in
the list.
