A Parsing Example

• Let's try this out with a script that will find and replace string text.
• The string text will be the body between the tags.
• The tag will have two attributes: add and remove.
• The tag handler will search the body text for the remove text, and replace it with the add text.
• If no remove text is found, the handler will return the string unaltered.
• The files
•  Replace.java The tag handler class that does the dirty work.
•  Edit53.jsp A JSP with body text that will be replaced.
•  EditUSB A JSP with no body text to be replaced.
•  edit.tld The tag library definition file for the Replace tag.
• Don't forget to add this to the web.xml file:

    <taglib>
        <taglib-uri>/edit</taglib-uri>
        <taglib-location>edit.tld</taglib-location>
    </taglib>

 The Results
