使用经典的 asp 进行正则表达式 [英] using classic asp for regular expression

问题描述

我们有一些经典的 asp 网站，我正在研究它们，我想知道如何编写正则表达式检查并提取匹配的表达式:

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:

我的表达式在脚本的名称中所以让我们这么说

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

Response.Write Request.ServerVariables("SCRIPT_NAME")

打印出来:

review_blabla.asp
review_foo.asp
review_bar.asp

如何从那里获取 blabla、foo 和 bar?

How can I get the blabla, foo and bar from there?

谢谢.

推荐答案

虽然 Yots 的答案几乎可以肯定是正确的，但您可以用更少的代码和更清晰的方式实现您正在寻找的结果:

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，我还没有找到比 Regexr 更好的 RegEx 游乐场，之前尝试您的 regex 模式非常棒深入研究代码.

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