replace: Replace an element
  
  Syntax

    'tal:replace' syntax::
  
      argument ::= (['text'] | 'structure') expression

  Description  

    The 'tal:replace' statement replaces an element with dynamic
    content.  It replaces the statement element with either text or a
    structure (unescaped markup).  The body of the statement is an
    expression with an optional type prefix.  The value of the
    expression is converted into an escaped string if you prefix the
    expression with 'text' or omit the prefix, and is inserted
    unchanged if you prefix it with 'structure'.  Escaping consists of
    converting "&" to "&", "<" to "<", and
    ">" to ">".

    If the value is *nothing*, then the element is simply removed.  If
    the value is *default*, then the element is left unchanged.

  Examples

    The two ways to insert the title of a template::

      <span tal:replace="template/title">Title</span>
      <span tal:replace="text template/title">Title</span>

    Inserting HTML/XML::

      <div tal:replace="structure table" />

    Inserting nothing::

      <div tal:replace="nothing">This element is a comment.</div>
