                StripDirective

Implementation of the `py:strip` template directive.

When the value of the `py:strip` attribute evaluates to `True`, the element is stripped from the output

    >>> from genshi.template import MarkupTemplate
    >>> tmpl = MarkupTemplate('''<div xmlns:py="http://genshi.edgewall.org/">
    ...   <div py:strip="True"><b>foo</b></div>
    ... </div>''')
    >>> print(tmpl.generate())
    <div>
      <b>foo</b>
    </div>

Leaving the attribute value empty is equivalent to a truth value.

This directive is particulary interesting for named template functions or match templates that do not generate a top-level element:

    >>> tmpl = MarkupTemplate('''<div xmlns:py="http://genshi.edgewall.org/">
    ...   <div py:def="echo(what)" py:strip="">
    ...     <b>${what}</b>
    ...   </div>
    ...   ${echo('foo')}
    ... </div>''')
    >>> print(tmpl.generate())
    <div>
        <b>foo</b>
    </div>
