使用正则表达式及字符串操作，抽取网页信息，实现代码如下：
/* 去script. */public static String trimScript(String content) {String regEx = "]*>[^<]+";Pattern p = Pattern.compile(regEx);Matcher m = p.matcher(content);String result = content;if (m.find()) {result = m.replaceAll("");}return result;}/* 去除注释*/public static String trimComment(String content) {String regEx = "";Pattern p = Pattern.compile(regEx);Matcher m = p.matcher(content);String result = content;if (m.find()) {result = m.replaceAll("");}return result;}/* 去除标签 */public static String trimTag(String content) {String regEx = "]+>";Pattern p = Pattern.compile(regEx);Matcher m = p.matcher(content);String result = content;if (m.find()) {result = m.replaceAll("");}result = result.replace(" ", "").replace(">", "").replace(">", "");return result;}/* 根据起始位置和结束位置，截取字符串 */public static String subString(String start, String end, String content) {int iStart = content.indexOf(start);int iEnd = content.indexOf(end);if (iStart < iEnd) {return content.substring(iStart, iEnd);}return null;}
要愈合不能，要忘却不能，要再次拥抱，却鼓不起足够的勇气，
