WordPress plugin : workaround to get excerpt of recent posts & only published messages

While integrating the blogs using wordpress plugin in one of the project I am working on. I observed that using current version(0.1) of wordpress plugin, when we request for recent posts, it returns not only published blogs but also blogs with status as draft(which are not yet published). Along with that, we needed to show excerpt of recent blogs. So the workaround I found is given below

//create a class blog
public class Blog{
    String title
    String description
    String link
}

/** A function that returns the requested number of recent published posts as  Blog objects list. Its parameters :
     * @param count : number of recent blogs needed.
     * @param textSize : number of charaters to be displayed in a description
     * @param blogsCount : it is used to make a recursive call, incase wordpress service returned draft posts as well.   Pass this value equivalent to count
     * @return List : Returns list of blog objects.
     */

  List getRecentExcerptedPosts(int count, int textSize, int blogsCount = count){

         List excerptPosts = []
         Blog blog
         int postsAdded=0
          try {
               //As blogs requested from wordpress may have draft posts, so we requested twice the number of blogs needed as this request to wordpress plugin is expensive.
               wordpressService.getRecentPosts(blogsCount*2).each { post ->
                   if(postsAdded < count){
                        if(post.post_status.equalsIgnoreCase('publish')){
                            blog = new Blog()
                            blog.title = post.title
                            blog.description = post.description.replaceAll("\\<.*?\\>","") //removes html code from description
                            blog.description = textSize > blog.description.length()?blog.description : blog.description.substring(0, textSize)
                            blog.link = post.permaLink
                            excerptPosts << blog
                            postsAdded++
                       }
                   }
               }
               if(postsAdded<count){
                   //makes the recursive call
                   excerptPosts= getRecentExcerptedPosts(count,textSize, blogsCount*2)
               }
            } catch (Exception e) {
                log.error "Error rendering the wordpress recentPosts tag", e
            }
            return excerptPosts
       }
