我有一个文本文件,如:
insert into table
values (‘test’,
<xml>
</xml>);
insert into table
values (‘test’,
<xml>
<xml>
<xml>
</xml>);
insert into table
values (‘test’,
<xml>
<xml>
<xml>
<xml>
<xml>
</xml>);
现在我希望我能在程序中单独读取每个insert
(完整语句)命令并对表执行。
我怎么能这样做?任何正则表达式都会有帮助吗?

你的意思是这样的吗?:
String str = "insert into table \n"
+ "values (‘test’,\n"
+ "<xml> \n"
+ "</xml>);\n"
+ "insert into table \n"
+ "values (‘test’,\n"
+ "<xml> \n"
+ "<xml>\n"
+ "<xml>\n"
+ "</xml>);\n"
+ "insert into table \n"
+ "values (‘test’,\n"
+ "<xml> \n"
+ "<xml>\n"
+ "<xml>\n"
+ "<xml>\n"
+ "<xml>\n"
+ "</xml>);";
String[] commands = str.split(";");
for(String command : commands)
{
System.out.println(command + ";");
}
收率:
insert into table
values (‘test’,
<xml>
</xml>);
insert into table
values (‘test’,
<xml>
<xml>
<xml>
</xml>);
insert into table
values (‘test’,
<xml>
<xml>
<xml>
<xml>
<xml>
</xml>);

将文件内容读入字符串。然后使用String.split();
String s = "insert into table values (‘test’,<xml> </xml>); insert into table values
( ‘test’,<xml>"
+ "<xml><xml></xml>); insert into table values (‘test’,<xml> <xml><xml><xml><xml>
</xml>);";
String[] test = s.split(";");
for(int i = 0; i < test.length; i++) {
System.out.println(test[i]);
}

您可以使用JDBC进行插入。参考例如 http://www.tutorialspoint.com/jdbc/jdbc-insert-records.htm
