asp正则表达式使用详解

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

<%
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
%>

<%
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)
%>

<%
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)
%>

<%
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)
%>

<%
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)
%>

<%
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
%>

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

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
%>
