asp正則表達式使用詳解

代碼如下:
Dim re
Set re = new RegExp '創(chuàng )建RegExp實(shí)例
re.Pattern = "ab+c" '定義正則表達式文字，你可以在這里替換正則表達式
Dim myString
myString = "abcefg" '定義要匹配的字符串，可以進(jìn)行替換
Response.write(re.Execute(myString)(0)) '進(jìn)行匹配測試，并寫(xiě)出結果

代碼如下:
<%
Dim re
Set re = new RegExp '創(chuàng )建RegExp實(shí)例
re.Pattern = "\w+" '定義正則表達式文字
Dim myString
myString = "VBScript version 5.6 provides many new features."
'進(jìn)行匹配測試，并寫(xiě)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
%>

代碼如下:
<%
Dim re
Set re = new RegExp '創(chuàng )建RegExp實(shí)例
re.Pattern = "\s" '定義正則表達式文字，這里是匹配空白
Dim myString
myString = "VBScript version 5.6 provides many new features."
myString = re.replace(myString, "-") '用-替換空白，返回替換后的字符串
'寫(xiě)出結果
Response.write(myString)
%>

代碼如下:
<%
Dim re
Set re = new RegExp '創(chuàng )建RegExp實(shí)例
re.Global = True
re.Pattern = "\s" '定義正則表達式文字，這里是匹配空白
Dim myString
myString = "VBScript version 5.6 provides many new features."
myString = re.replace(myString, "-") '用-替換空白，返回替換后的字符串
'寫(xiě)出結果
Response.write(myString)
%>

代碼如下:
<%
Dim re
Set re = new RegExp '創(chuàng )建RegExp實(shí)例
re.Global = True
re.Pattern = "(\w+)-(\w+)" '定義正則表達式模式文字
Dim myString
myString = "flip-flop"
myString = re.replace(myString, "$1-$2")
'$1表示第一個(gè)\w+，$2表示第二個(gè)\w+，第一個(gè)\w+匹配flip，第二個(gè)\w+匹配flop，
'所以$1-$2相當于flip-flop
'寫(xiě)出結果
Response.write(myString)
%>

代碼如下:
<%
Dim re
Set re = new RegExp '創(chuàng )建RegExp實(shí)例
re.Global = True
re.Pattern = "(\S+)(\s+)(\S+)" '定義正則表達式模式文字
Dim myString
myString = "flip flop"
myString = re.replace(myString, "$3$2$1")
'$1表示第一個(gè)\S+，$3表示第二個(gè)\S+，$2表示\s+，
'所以$3$2$1相當于flop flip
'寫(xiě)出結果
Response.write(myString)
%>

代碼如下:
<%
Dim re
Set re = new RegExp '創(chuàng )建RegExp實(shí)例
re.Global = True
re.Pattern = "\w+" '定義正則表達式模式文字
Dim myString
myString = "VBScript version 5.6 provides many new features."
Set Matches = re.Execute(myString) '執行搜索，該集合用來(lái)保存匹配的結果
'進(jìn)行匹配測試，并寫(xiě)出結果
'迭代Matches集合
For Each Match in Matches
'寫(xiě)出結果
Response.write(Match.FirstIndex & "-" & (Match.FirstIndex + Match.Length) & " " & Match.Value & "<br />")
Next
%>

代碼如下:
<%
Dim re
Set re = new RegExp '創(chuàng )建RegExp實(shí)例
're.Global = True 注釋掉這一行
re.Pattern = "\w+" '定義正則表達式模式文字
Dim myString
myString = "VBScript version 5.6 provides many new features."
Set Matches = re.Execute(myString) '執行搜索，該集合用來(lái)保存匹配的結果
'進(jìn)行匹配測試，并寫(xiě)出結果
'迭代Matches集合
For Each Match in Matches
'寫(xiě)出結果
Response.write(Match.FirstIndex & "-" & (Match.FirstIndex + Match.Length) & " " & Match.Value & "<br />")
Next
