我们的代码当中有很多很多如下的代码：
UarrMain[0] := AsMainType(edLayer, myStr, 'Layer', '结构层名称');
UarrMain[1] := AsMainType(edKind, myStr, 'Kind', '稳定剂种类');
.......
UArrSub[0] := AsSubType(myInt, True, 'seqnum', '序号');
UArrSub[1] := AsSubType(myStr, False, 'BoxNumber', '试验盒号');
UArrSub[2] := AsSubType(myFloat, False, 'BoxWeigth', '盒的质量');
.....
我现在需要提取第三个，第四个参数。
放上来，下次电脑坏就不用重新写了。工作当中用到的，可以减轻工作量。
一边学一边写的，比较手生，翻了很多次文档才写出来。关键是正则，当然没有考虑所有的情况。
这门语言对GUI支持的不好，因为是面向服务器的开发。就胡乱弄了个B/S的，代码如下：
package main
import
(
"io"
"fmt"
"regexp"
"strings"
"net/http"
)
const(
SQL = "EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N'AAAA', @level0type=N'SCHEMA',@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'CCCC', @level2type=N'COLUMN',@level2name=N'BBBB'"
SQL2 = "EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N'AAAA', @level0type=N'SCHEMA',@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'CCCC'"
html =
`<html>
<head><title>提取<a/title></head>
<body><form method = 'post'>
TableName : <input type = "text" name = "tablename"></input> qs_Table 中的 TableName,比如 TestRecordC21 <br></br>
表格名称 : <input type = "text" name = "tablename2"></input>比如 石料试验记录 <br></br>
<textarea rows="20" cols="120" name = "target"></textarea><br></br>
<input type = "submit" value = "Submit"></input>
%s
</form>
</body>
</html>`
