使用传统的ASP定期EX pression [英] using classic asp for regular expression

问题描述

我们有一些经典的ASP网站，我对他们的工作莉儿一点，我想知道我怎么能写一个正前pression检查，并提取匹配的前pression：

We have some Classic asp sites, and i'm working on them a lil' bit, and I was wondering how can I write a regular expression check, and extract the matched expression:

恩pression我是在脚本的名字
所以我们说，这

the expression I have is in the script's name so Let's say this

Response.Write Request.ServerVariables("SCRIPT_NAME")

打印出：

review_blabla.asp
review_foo.asp
review_bar.asp

我怎样才能获得布拉布拉，富和栏从那里？

感谢。

推荐答案

虽然Yots'答案几乎肯定是正确的，你可以实现你少了很多code和较为清晰地寻找的结果：

Whilst Yots' answer is almost certainly correct, you can achieve the result you are looking for with a lot less code and somewhat more clearly:

'A handy function i keep lying around for RegEx matches'
Function RegExResults(strTarget, strPattern)

    Set regEx = New RegExp
    regEx.Pattern = strPattern
    regEx.Global = true
    Set RegExResults = regEx.Execute(strTarget)
    Set regEx = Nothing

End Function

'Pass the original string and pattern into the function and get a collection object back'
Set arrResults = RegExResults(Request.ServerVariables("SCRIPT_NAME"), "review_(.*?)\.asp")

'In your pattern the answer is the first group, so all you need is'
For each result in arrResults
    Response.Write(result.Submatches(0))
Next

Set arrResults = Nothing

此外，我还没有找到gskinner.com 更好正则表达式的操场比之一，它的辉煌的尝试您正则表达式图案潜入code之前。

Additionally, I have yet to find a better RegEx playground than the one on gskinner.com, it's brilliant for trying out your regex patterns before diving into code.
