Using HTML.Attribute
You often need to look at the attributes of a particular HTML tag, and the HTML.Attribute class is used to represent an HTML tag. Table 2 lists the 80 HTML attributes recognized by the Swing HTML parser. The handleSimpleTag and handleStartTag pass in a MutableAttributeSet that contains a list of attributes. For example, to retrieve the HREF attribute from a MutableAttributeSet named a, use the following command:
String value = a.getAttribute(HTML.Attribute.HREF);
Table 2 shows all available attribute constants.

If you construct your own parser call back, it will look something like Listing 2.
Listing 2: A Custom Callback Template
protected class Parser
extends HTMLEditorKit.ParserCallback {
public void handleComment(char[] data,int pos)
{
// insert code to handle comments
}
public void handleEndTag(HTML.Tag t,int pos)
{
// insert code to handle ending tags
}
public void handleError(String errorMsg,int pos)
{
// insert error handling code
}
public void handleSimpleTag(HTML.Tag t,
MutableAttributeSet a,int pos)
{
// insert code to handle simple tags
}
public void handleStartTag(HTML.Tag t,
MutableAttributeSet a,int pos)
{
// insert code to handle starting tags
}
}
