关于使用快捷码从变量输出HTML时的冗余代码

我使用shortcode在一个变量中输出以下html，但有太多冗余代码，如br和p标记，如何删除它们？谢谢

HTML组成

$return_html.=\'<div class="portfolio-item" id="portfolio-\'.$post->ID.\'"><a class="overlay\'.$class.\'" href="\'.$url.\'" title="\'.$post->post_title.\'"><h3>\'.$post->post_title.\'</h3><p class="intro">\'.van_truncate($post->post_content,100).\'</p></a><div class="tools"><a href="\'.$url.\'" class="zoomin\'.$class.\'" title="\'.$post->post_title.\'">ZoomIn</a><a href="\'.get_permalink($post->ID).\'" class="info">Info</a></div>
<a href="\'.get_permalink($post->ID).\'" class="item"><img src="\'.get_template_directory_uri().\'/images/pixel.gif" data-url="\'.$thumbnail_url[0].\'" class="scrollLoading" /></a></div>\';

当前短码函数

add_shortcode(\'portfolios\', \'van_portfolios_shortcode\');
function van_portfolios_shortcode( $atts, $content) {
    extract(shortcode_atts(array(
        \'number\'=>\'9\',
        \'slug\'=>\'\'
    ), $atts)); 
   $str=van_portfolios($slug,$number,false);
   return $str;
}

function van_process_shortcode($content) {
    global $shortcode_tags;
    // Backup current registered shortcodes and clear them all out
    $orig_shortcode_tags = $shortcode_tags;
    $shortcode_tags = array();
    add_shortcode(\'portfolios\', \'van_portfolios_shortcode\');

    // Do the shortcode (only the one above is registered)
    $content = do_shortcode($content);
    // Put the original shortcodes back
    $shortcode_tags = $orig_shortcode_tags;
    return $content;
}
add_filter(\'the_content\', \'van_process_shortcode\', 7);

正确的化妆是

<div class="portfolio-item">
           <a class="overlay" href="#">
             <h3>...</h3>
             <p>...</p>
           </a>
           <div class="tools"><a href="#" class="zoomin" rel="lightbox">ZoomIn</a><a href="#" class="info">Info</a></div>
           <a href="#" class="item">...</a>
         </div>

输出：

<div class="portfolio-item">
           <a class="overlay" href="#">
             <br /><!--This <br />is redundant code-->
             <h3>...</h3>
             <p>...</p><p><!--This <p> is redundant code-->
           </a>
           <div class="tools"><a href="#" class="zoomin" rel="lightbox">ZoomIn</a><a href="#" class="info">Info</a></div>
           <p><!--This <p> is redundant code--><a href="#" class="item">...</a>
         </div>

// This will do nothing but will allow the shortcode to be stripped add_shortcode( \'foobar\', \'shortcode_foobar\' ); // Actual processing of the shortcode happens here function foobar_run_shortcode( $content ) { global $shortcode_tags; // Backup current registered shortcodes and clear them all out $orig_shortcode_tags = $shortcode_tags; remove_all_shortcodes(); add_shortcode( \'foobar\', \'shortcode_foobar\' ); // Do the shortcode (only the one above is registered) $content = do_shortcode( $content ); // Put the original shortcodes back $shortcode_tags = $orig_shortcode_tags; return $content; } add_filter( \'the_content\', \'foobar_run_shortcode\', 7 );
