如何解析星级而不是字符串？

Question

我试图解析来自这个网站的信息http://www.petwave.com/Dogs/Breeds/Airedale-Terrier.aspx ..最后是一张带有星级评分的几个属性的表格。现在我只有字符串解析的值..无论如何要解析网站的评级？我想将这些值（如Lifespan和origin）更改为星值？知道怎么做吗？

   private String name;
   private String origin;

   private boolean basicDataReady = false;
   private boolean detailDataReady = false;

     Dog(String name, String sizeType, String thumbnailURL, String url,    Breed.Name breed) {
      this.name = name;
      this.sizeType = sizeType;
      this.thumbnailURL = thumbnailURL;
      this.url = url;
      this.breed = breed;
      basicDataReady = true;
  }
