# ABSTRACT: adaptor for HTML::Element

=head1 SYNOPSIS

See L<Tree::Template::Declare>.

=head1 SPECIFICITIES

This module will build trees using L<HTML::Element>.

To create text nodes, you would be forced to say:

  node {
    name '~text';
    attribs text => 'some text';
  }

which is too cumbersone. You can instead use:

  text_node 'some text';

HTML::Element's C<deobjectify_text> method will be called by
C<finalize_tree> before returning the tree object.
