asp正则表达式使用详解
代码如下:
Dim re Set re = new RegExp '创建RegExp实例 re.Pattern = "ab+c" '定义正则表达式文字,你可以在这里替换正则表达式 Dim myString myString = "abcefg" '定义要匹配的字符串,可以进行替换 Response.write(re.Execute(myString)(0)) '进行匹配测试,并写出结果
代码如下:
<% Dim re Set re = new RegExp '创建RegExp实例 re.Pattern = "\w+" '定义正则表达式文字 Dim myString myString = "VBScript version 5.6 provides many new features." '进行匹配测试,并写出是否匹配成功 If re.Test(myString) Then Response.write("匹配成功!") Else Response.write("匹配不成功!") End If %>
代码如下:
<% Dim re Set re = new RegExp '创建RegExp实例 re.Pattern = "\s" '定义正则表达式文字,这里是匹配空白 Dim myString myString = "VBScript version 5.6 provides many new features." myString = re.replace(myString, "-") '用-替换空白,返回替换后的字符串 '写出结果 Response.write(myString) %>
代码如下:
<% Dim re Set re = new RegExp '创建RegExp实例 re.Global = True re.Pattern = "\s" '定义正则表达式文字,这里是匹配空白 Dim myString myString = "VBScript version 5.6 provides many new features." myString = re.replace(myString, "-") '用-替换空白,返回替换后的字符串 '写出结果 Response.write(myString) %>
代码如下:
<% Dim re Set re = new RegExp '创建RegExp实例 re.Global = True re.Pattern = "(\w+)-(\w+)" '定义正则表达式模式文字 Dim myString myString = "flip-flop" myString = re.replace(myString, "$1-$2") '$1表示第一个\w+,$2表示第二个\w+,第一个\w+匹配flip,第二个\w+匹配flop, '所以$1-$2相当于flip-flop '写出结果 Response.write(myString) %>
代码如下:
<% Dim re Set re = new RegExp '创建RegExp实例 re.Global = True re.Pattern = "(\S+)(\s+)(\S+)" '定义正则表达式模式文字 Dim myString myString = "flip flop" myString = re.replace(myString, "$3$2$1") '$1表示第一个\S+,$3表示第二个\S+,$2表示\s+, '所以$3$2$1相当于flop flip '写出结果 Response.write(myString) %>
代码如下:
<% Dim re Set re = new RegExp '创建RegExp实例 re.Global = True re.Pattern = "\w+" '定义正则表达式模式文字 Dim myString myString = "VBScript version 5.6 provides many new features." Set Matches = re.Execute(myString) '执行搜索,该集合用来保存匹配的结果 '进行匹配测试,并写出结果 '迭代Matches集合 For Each Match in Matches '写出结果 Response.write(Match.FirstIndex & "-" & (Match.FirstIndex + Match.Length) & " " & Match.Value & "<br />") Next %>
代码如下:
<% Dim re Set re = new RegExp '创建RegExp实例 're.Global = True 注释掉这一行 re.Pattern = "\w+" '定义正则表达式模式文字 Dim myString myString = "VBScript version 5.6 provides many new features." Set Matches = re.Execute(myString) '执行搜索,该集合用来保存匹配的结果 '进行匹配测试,并写出结果 '迭代Matches集合 For Each Match in Matches '写出结果 Response.write(Match.FirstIndex & "-" & (Match.FirstIndex + Match.Length) & " " & Match.Value & "<br />") Next %>
代码如下:
<%@language="vbscript" codepage="65001"%> <% '创建一个连接,并且创建一个ADODB.Command用于操作 Dim oCmd,oConn Set oConn = Server.CreateObject("ADODB.Connection") Set oCmd = Server.CreateObject("ADODB.Command") oConn.ConnectionString = "Provider=SQLOLEDB;server = myhost;Initial Catalog = myDatabase;UID=sa;PWD=verysecret;" oConn.Open '这里创建一个SQL CREATE TABLE语句 Set oCmd.ActiveConnection = oConn oCmd.CommandText = "CREATE TABLE NewEmployees(firstName nvarchar (50),lastName nvarchar (50),EmpType nvarchar (50))" '执行创建数据表操作 oCmd.Execute Response.Write("操作成功!") %> <% '显式的关闭连接 oConn.Close Set oConn = Nothing %>
