<div class="wpex-recent-posts-content clr">
<a href="<?php the_permalink(); ?>" title="<?php the_title_attribute(); ?>"><?php the_title(); ?></a><p>
<?php
    $content = the_content();
    echo substr($content,0,100);

试试这个:

$content = get_the_content();
$content = strip_tags($content);
echo substr($content, 0, 100);
