如下所示:
/** * 得到网页中图片的地址 * @param sets html字符串 */ public Set<String> getImgStr(String htmlStr) { Set<String> pics = new HashSet<String>(); String img = ""; Pattern p_image; Matcher m_image; String regEx_img = "<img.*src\s*=\s*(.*?)[^>]*?>"; p_image = Pattern.compile(regEx_img, Pattern.CASE_INSENSITIVE); m_image = p_image.matcher(htmlStr); while (m_image.find()) { // 得到<img />数据 img = m_image.group(); // 匹配<img>中的src数据 Matcher m = Pattern.compile("src\s*=\s*"?(.*?)("|>|\s+)").matcher(img); while (m.find()) { pics.add(m.group(1)); } } return pics; }
