This depends on how you've solved the rest of this. Here's an idea: Have every link tag add its link and text to a list (such as an ArrayList) in page scope (or in the nav-tag using findAncestorWithClass), then have nav.doEndTag look at the size of the list, and print the elements in order. (You can use an Iterator and check if it hasNext() )
Other possibilities would be - Use a StringTokenizer and count some tag (as tokens) in nav.doStartTag - Have each link tag increment a variable in page scope and look at it nav's doEndTag Mattias Jiderhamn Expert Systems [EMAIL PROTECTED] > -----Original Message----- > From: James Childers [mailto:[EMAIL PROTECTED]] > Sent: Friday, November 16, 2001 9:58 PM > Subject: Counting body tag elements in custom tag > > All, > > I am implementing a custom tag to display a breadcrumb.
