class wobzilla_variableHandler

A Variable-Handler can automate variable-handling in container-elements. It stores the variable values into an context-object. Assume the following Configuration:

  <variable name="books">
   <for-each select="author/books">
    <value-of select="@name">;
   </for-each>
  </variable>
  <variable name="count" select="count(author/books)"/>
  <variable name="book-writer" select="$count > 0"/>

• outputContext.get("books") returns "'Book A;Book B;'".
• outputContext.get("count") returns "2".
• outputContext.get("book-writer") returns "true()".
