To create your own scanner that can hold children, create a subclass of this class. The composite tag scanner can be configured with:

• Tags which will trigger a match
• Tags which when encountered before a legal end tag, should force a correction
• Preventing more tags of its own type to appear as children

Here are examples of each:
Tags which will trigger a match If we wish to recognize <mytag>,

 
  MyScanner extends CompositeTagScanner {
    private static final String [] MATCH_IDS = { "MYTAG" };
 	 MyScanner() {
 		super(MATCH_IDS);
 	 }
 	 ...
  }
  
 

Tags which force correction If we wish to insert end tags if we get a or without recieving </mytag>

 
  MyScanner extends CompositeTagScanner {
    private static final String [] MATCH_IDS = { "MYTAG" };
    private static final String [] ENDERS = {};
    private static final String [] END_TAG_ENDERS = { "BODY", "HTML" };
 	 MyScanner() {
 		super(MATCH_IDS, ENDERS, END_TAG_ENDERS, true);
 	 }
 	 ...
  }
  
 

Preventing children of same type This is useful when you know that a certain tag can never hold children of its own type. e.g. <FORM> can never have more form tags within it. If it does, it is an error and should be corrected. The default behavior is to allow nesting.

 
  MyScanner extends CompositeTagScanner {
    private static final String [] MATCH_IDS = { "FORM" };
    private static final String [] ENDERS = {};
    private static final String [] END_TAG_ENDERS = { "BODY", "HTML" };
 	 MyScanner() {
 		super(MATCH_IDS, ENDERS,END_TAG_ENDERS, false);
 	 }
 	 ...
  }
  
 

Inside the scanner, use createTag() to specify what tag needs to be created.
