Examples of org.htmlparser.scanners.CompositeTagScanner

• org.htmlparser.scanners.CompositeTagScanner
  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.
