### 本文使用正则方式，解析HTML代码段里面图片内容，视频内容，文字描述，具体看一下代码： ###

package zhoushitong;
 
 import java.util.ArrayList;
 import java.util.List;
 import java.util.regex.Matcher;
 import java.util.regex.Pattern;
 
 public class test {
 
 public static void main(String[] args) {
 String string = "<table style=\"float: left; font-size: 12px;margin-bottom:10px;border:1px solid #CCC;width:100%;border-collapse:inherit;padding:8px;border-top:none\"><tbody><tr class=\"firstRow\"><td width=\"220\" valign=\"top\" style=\"float: left; display: inline; width: 220px; height: 18px; overflow: hidden; margin: 10px 15px 0px 0px; line-height: 18px; vertical-align: top; white-space: nowrap; text-overflow: ellipsis; color: rgb(102, 102, 102); word-break: break-all;\">品牌： 巴巴腾</td><td width=\"220\" valign=\"top\" style=\"float: left; display: inline; width: 220px; height: 18px; overflow: hidden; margin: 10px 15px 0px 0px; line-height: 18px; vertical-align: top; white-space: nowrap; text-overflow: ellipsis; color: rgb(102, 102, 102); word-break: break-all;\">货号：A1</td><td width=\"220\" valign=\"top\" style=\"list-style: none; float: left; white-space: nowrap; text-overflow: ellipsis; display: inline; height: 18px; overflow: hidden; line-height: 18px; vertical-align: top; color: rgb(102, 102, 102); margin: 10px 15px 0px 0px; word-break: break-all;\">颜色分类：白色</td></tr><tr><td width=\"220\" valign=\"top\" style=\"float: left; display: inline; width: 220px; height: 18px; overflow: hidden; margin: 10px 15px 0px 0px; line-height: 18px; vertical-align: top; white-space: nowrap; text-overflow: ellipsis; color: rgb(102, 102, 102); word-break: break-all;\">材质：PVC</td><td width=\"220\" valign=\"top\" style=\"float: left; display: inline; width: 220px; height: 18px; overflow: hidden; margin: 10px 15px 0px 0px; line-height: 18px; vertical-align: top; white-space: nowrap; text-overflow: ellipsis; color: rgb(102, 102, 102); word-break: break-all;\"></td><td width=\"220\" valign=\"top\" style=\"float: left; display: inline; width: 220px; height: 18px; overflow: hidden; margin: 10px 15px 0px 0px; line-height: 18px; vertical-align: top; white-space: nowrap; text-overflow: ellipsis; color: rgb(102, 102, 102); word-break: break-all;display:none\"></td></tr></tbody></table><video src=\"./data/files/video/20171130/1512044000315028.mp4\" autoplay=\"true\" class=\"edui-upload-video video-js vjs-default-skin video-js\" controls=\"\" preload=\"none\" width=\"70%\" height=\"70%\"></video><img src=\"./data/files/store_2/goods_49/201711301644098301.jpg\" alt=\"7_01-jpg.jpg\"/><img src=\"./data/files/store_2/goods_49/201711301644094874.jpg\" alt=\"7_02-jpg.jpg\"/><img src=\"./data/files/store_2/goods_49/201711301644099889.jpg\" alt=\"7_03-jpg.jpg\"/><img src=\"./data/files/store_2/goods_49/201711301644093468.jpg\" alt=\"7_04-jpg.jpg\"/><img src=\"./data/files/store_2/goods_50/201711301644102839.jpg\" alt=\"7_05-jpg.jpg\"/><img src=\"./data/files/store_2/goods_50/201711301644104379.jpg\" alt=\"7_06-jpg.jpg\"/><img src=\"./data/files/store_2/goods_50/201711301644106072.jpg\" alt=\"7_07-jpg.jpg\"/><img src=\"./data/files/store_2/goods_51/201711301644111540.jpg\" alt=\"7_08-jpg.jpg\"/><img src=\"./data/files/store_2/goods_147/201808021039077422.png\" alt=\"7.png\"/>";
 
 //解析html代码段中的图片
 String srcReg = "<img[^<>]*?\\ssrc=['\"]?(.*?)['\"]?(\\s.*?)?>";
 List<String> imgList = match(string,srcReg);
 System.out.println("解析html图片为："+ imgList);
 
 //解析html代码段中的视频

 List<String> videoList = match(string,videoReg);
 System.out.println("解析html视频为："+ videoList);
 
 //解析html代码段中的文字，通过观察发现文字使用span标签，所以要编写span的正则
 String span = "<span(?:.*?)?>(.*?)";
 List<String> spanList = match(string,span);
 System.out.println("解析html文字为："+ spanList);
 
 //变迁td和em标签分别为
 String em = "<em(?:.*?)?>(.*?)";
 String td = "<td(?:.*?)?>(.*?)</td>";
 List<String> tdList = match(string,td);
 List<String> emList = match(string,em);
 System.out.println("解析html里td标签为：" + tdList + "解析html里em标签为：" + emList);
 
 }
 /**
 * 正则处理html代码段
 * @param source

 * @return
 */
 public static List<String> match(String source,String reg){
 List<String> result = new ArrayList<>();
 Matcher m = Pattern.compile(reg).matcher(source);
 while (m.find()){
 String r = m.group(1);
 result.add(r);
 }
 return result;
 }
 
 }

执行返回结果为：

解析html图片为：[./data/files/store_2/goods_49/201711301644098301.jpg, ./data/files/store_2/goods_49/201711301644094874.jpg, ./data/files/store_2/goods_49/201711301644099889.jpg, ./data/files/store_2/goods_49/201711301644093468.jpg, ./data/files/store_2/goods_50/201711301644102839.jpg, ./data/files/store_2/goods_50/201711301644104379.jpg, ./data/files/store_2/goods_50/201711301644106072.jpg, ./data/files/store_2/goods_51/201711301644111540.jpg, ./data/files/store_2/goods_147/201808021039077422.png]
 解析html视频为：[./data/files/video/20171130/1512044000315028.mp4]
 解析html文字为：[]
 解析html文字为：[品牌： 巴巴腾, 货号：A1, 颜色分类：白色, 材质：PVC, , ]
