如何删除字符串中的html标签？

Question

when i search keyword " data ", i get abtract of paper in digital library :

Many organizations often underutilize their existing <span class='snippet'>data</span> warehouses. In this paper, we suggest a way of acquiring more information from corporate <span class='snippet'>data</span> warehouses without the complications and drawbacks of deploying additional software systems. Association-rule mining, which captures co-occurrence patterns within <span class='snippet'>data</span>, has attracted considerable efforts from <span class='snippet'>data</span> warehousing researchers and practitioners alike. Unfortunately, most <span class='snippet'>data</span> mining tools are loosely coupled, at best, with the <span class='snippet'>data</span> warehouse repository. Furthermore, these tools can often find association rules only within the main fact table of the <span class='snippet'>data</span> warehouse (thus ignoring the information-rich dimensions of the star schema) and are not easily applied on non-transaction level <span class='snippet'>data</span> often found in <span class='snippet'>data</span> warehouses

How can i remove all tag <span class='snippet'>..</span> , but still keep keywod data to have abtract like that :

strip_tags() is your friend. Code kindly copied from here .

  public static String strip_tags(String text, String allowedTags) {
      String[] tag_list = allowedTags.split(",");
      Arrays.sort(tag_list);

      final Pattern p = Pattern.compile("<[/!]?([^\\\\s>]*)\\\\s*[^>]*>",
              Pattern.CASE_INSENSITIVE);
      Matcher m = p.matcher(text);

      StringBuffer out = new StringBuffer();
      int lastPos = 0;
      while (m.find()) {
          String tag = m.group(1);
          // if tag not allowed: skip it
          if (Arrays.binarySearch(tag_list, tag) < 0) {
              out.append(text.substring(lastPos, m.start())).append(" ");

          } else {
              out.append(text.substring(lastPos, m.end()));
          }
          lastPos = m.end();
      }
      if (lastPos > 0) {
          out.append(text.substring(lastPos));
          return out.toString().trim();
      } else {
          return text;
      }
  }
