//
// SYNOPSIS
//
bool perl_visitor::operator()(
HTML_Node *node, int depth, bool is_end_tag
) const
//
// DESCRIPTION
//
// This function serves as the "glue code" between the called visitor
// function in C++ and the real visitor function in Perl.
//
// PARAMETERS
//
// node The HTML node we're currently visiting.
//
// depth How far down into the HTML tree we are (depth starts at
// zero).
//
// is_end_tag This is set to true only after visiting all of an HTML
// node's child nodes, if any.
//
// RETURN VALUE
//
// Returns the value of the Perl function.
//
// SEE ALSO
//
// Sriram Srinivasan. "Advanced Perl Programming," O'Reilly and
// Associates, Inc., Sebastopol, CA, 1997, pp. 352-353.
