filterdup Function

Filters duplicate elements from a list. Given a list, it returns a new list in which duplicate entries have been removed.

Example 1

<filterdup>
   <list>
      <s>apples</s>
      <s>oranges</s>
      <s>apples</s>
   </list>
</filterdup>

This expression returns the following list.

<list>
   <s>apples</s>
   <s>oranges</s>
</list>

Example 2

You can also use this function to manipulate an existing list rather than creating a new list.

<filterdup name = ’namedlist’/>
