filternull Function

Filters null elements from a list.

This function returns a single list removing all null elements (when given one list).

Example

<filternull>
   <list>
      <s>apples</s>
      <null>
         <s>oranges</s>
      <null/>
   </list>
</filternull>

This expression returns the following list.

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

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

<filternull name = ’namedlist’/>
