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：
我所拥有的表达式是脚本的名称
所以我们这样说吧
- Response.Write Request.ServerVariables("SCRIPT_NAME")
打印出来：
- review_blabla.asp
- review_foo.asp
- review_bar.asp
我怎么能从那里得到blabla,foo和bar？
谢谢.
虽然Yots的答案几乎肯定是正确的,但您可以通过更少的代码和更清晰的方式实现您正在寻找的结果：
- '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
另外,我还没有找到更好的RegEx playground than Regexr,在试用代码之前试用你的正则表达式是很棒的.
