Java中利用正则表达式截取指定字符串之间的内容

public static void main(String[] args) { String returnXml = "<resultdescription>单据 16613dd7d9a00000000000000000000vouchergl0 开始处理...单据 16613dd7d9a00000000000000000000vouchergl0 处理完毕!" + "</resultdescription>" + "<content>2018.09-记账凭证-5</content>" + "<billpk></billpk><bdocid>16613dd7d9a00000000000000000000vouchergl0</bdocid>" + "<filename>vouchergld861102.xml</filename><resultcode>1</resultcode>" + "<resultdescription>单据 16613dd7d9a00000000000000000000vouchergl0 开始处理...单据 16613dd7d9a00000000000000000000vouchergl0 处理完毕!" + "</resultdescription>" + "<content>2018.09-记账凭证-6</content></sendresult>"; String regex = "<content>(.*?)</content>"; List<String> list = new ArrayList<String>(); List<String> extvounoLists = new ArrayList<String>(); Pattern pattern = Pattern.compile(regex); Matcher m = pattern.matcher(returnXml); while (m.find()) { int i = 1; list.add(m.group(i)); i++; } for (String str : list) { System.out.println(str); String[] strs = str.split("-"); String strss = strs[strs.length-1]; extvounoLists.add(strs[strs.length-1]); } for (String string : extvounoLists) { System.out.println(string); } }
