I have created custom block in my custom module. I have created block template file into module templates folder. Custom block content coming successfully as per given in block__MODULENAME__dummmy_xyz.tpl.php file. I have only added following code into my block tpl file:

    <div class="wrapperDummy">Hello</div>

But it is coming with block parent div's, Block id and block-inner tag. I dont want to show those extra div's.
Following is the hook_theme which I have in my module file:

    /*
     * Implements hook_theme().
     */
    function MODULENAME_theme($existing, $type, $theme, $path) {
        
        $items = array();
    
        $items['MODULENAME_dummmy_xyz_block_theme'] = array(
            'type' => 'theme',
            'path' => drupal_get_path('module', 'MODULENAME') . '/templates',
            'template' => 'block__MODULENAME__dummmy_xyz',
            'variables'  => array()
        );
        return $items;
    }

I am rendering block into tpl using,

    $block = block_load('MODULENAME','dummmy_xyz');
    print drupal_render(_block_get_renderable_array(_block_render_blocks(array($block))));

block.tpl.php code:

    <?php print $outer_prefix . $inner_prefix; ?>
      <?php print render($title_prefix); ?>
    
      <?php if ($title): ?>
        <h2<?php print $title_attributes; ?>><?php print $title; ?></h2>
      <?php endif; ?>
    
      <?php print $content_processed; ?>
    
      <?php print render($title_suffix); ?>
    <?php print $inner_suffix . $outer_suffix; ?>

Kindly guide me.
