WordPress SimplePie修改

我正在使用WordPress中提供的fetch\\u feed（）函数来构建SimplePie提要对象。

WP的代码如下：

function fetch_feed($url) {
require_once (ABSPATH . WPINC . \'/class-feed.php\');

$feed = new SimplePie();

$feed->set_sanitize_class( \'WP_SimplePie_Sanitize_KSES\' );
// We must manually overwrite $feed->sanitize because SimplePie\'s
// constructor sets it before we have a chance to set the sanitization class
$feed->sanitize = new WP_SimplePie_Sanitize_KSES();

$feed->set_cache_class( \'WP_Feed_Cache\' );
$feed->set_file_class( \'WP_SimplePie_File\' );

$feed->set_feed_url($url);
$feed->set_cache_duration( apply_filters( \'wp_feed_cache_transient_lifetime\', 12 * HOUR_IN_SECONDS, $url ) );
do_action_ref_array( \'wp_feed_options\', array( &$feed, $url ) );
$feed->init();
$feed->handle_content_type();

if ( $feed->error() )
    return new WP_Error(\'simplepie-error\', $feed->error());

return $feed;
}

如何修改在提要导入期间剥离的HTML元素？

SimplePie在其文档中说有一个函数strip\\u htmltags（），但我不确定如何在WordPress上下文中使用它。http://simplepie.org/wiki/reference/simplepie/strip_htmltags

以下是我尝试过但没有成功的方法：

function wpse87359_feed_options( $feed) {
$feed->strip_htmltags(array_merge($feed->strip_htmltags, array(\'h1\', \'a\', \'img\',\'em\')));
}
add_action( \'wp_feed_options\', \'wpse87359_feed_options\' );

/** * Add in our filter when we run fetch_feed() */ function se87359_add_filter( &$feed, $url ) { add_filter(\'wp_kses_allowed_html\', \'se87359_add_allowed_tags\'); } add_filter( \'wp_feed_options\', \'se87359_add_filter\', 10, 2 ); function se87359_add_allowed_tags($tags) { // Ensure we remove it so it doesn\'t run on anything else remove_filter(\'wp_kses_allowed_html\', \'se87359_add_allowed_tags\'); $tags[\'mytag\'] = array(\'myattr\' => true); return $tags; }
