文件名 正则表达式提取方法

下面这段子程基本上可以算是比较不错的通用匹配了。(PS:我突然发现CODE_LITE把我的UBB转义了！！！晕,我只好自己转义了。。。)

Dim objRegExp,Matches,i,DC9_DOT_CN_MATCH
Dim aryMatch()
Redim Preserve aryMatch(0)
Set objRegExp=New RegExp
objRegExp.IgnoreCase =True
objRegExp.Global=True
objRegExp.Pattern=”(?:\[[^\]]+\]([^\[]+)\[\/[^\]]+\])|(?:(?:href|src)=([^\s|^>]+)[“”|>|\s\’])”
Set Matches = objRegExp.Execute(“[img]2312.jpg[/img][img]2312.jpg[/img]hh[img]http://www.dc9.cn/cm/upload/2ed312.jpg[/img] href=””http://www.dc9.cn/dccdd.jpg””>[IMG_RIGHT=400,300,title]upload/2assas.jpg[/IMG_RIGHT]<sctipt src=""http://www.dc9.cn/upload/sss.jpg""")
Dim TmpMatch
For i=0 to Matches.Count-1
Call InsertDataToArray(Matches(i).SubMatches(0),aryMatch)
Call InsertDataToArray(Matches(i).SubMatches(1),aryMatch)
Next

For i=0 to Ubound(aryMatch)
If Not IsNull(aryMatch(i)) And Trim(aryMatch(i))”” Then Response.write aryMatch(i)&”
”
Next

Function InsertDataToArray(Data,ByRef aryMatch)
If Trim(Data)”” Then
Data=Replace(Data,”‘”,””)
Data=Replace(Data,””””,””)
Data=Replace(Data,”\”,”/”)
Data=Split(Data,”/”)(Ubound(Split(Data,”/”)))
Redim Preserve aryMatch(Ubound(aryMatch)+1)
DC9_DOT_CN_MATCH=False
For j=0 to Ubound(aryMatch)
If aryMatch(j)=Data Then DC9_DOT_CN_MATCH=True
Next
If Not DC9_DOT_CN_MATCH Then aryMatch(Ubound(aryMatch))=Data
End If
End Function
实际上，Z-Blog的话就匹配Upload就可以了（但是我为了省事，也为了更精确些，就干脆在上面的那个匹配上面加上了upload，所以看上去好像下面这个更复杂些，其实理论上应该下面这个简单些，毕竟有upload管着呢。。），也不用SPLit那个/.这么写就可以了：

Dim objRegExp,Matches,i,ZC_UPLOAD_MATCH
Dim aryMatch()
Redim Preserve aryMatch(0)
Set objRegExp=New RegExp
objRegExp.IgnoreCase =True
objRegExp.Global=True
objRegExp.Pattern=”(?:\[[^\]]+\][^\[]*upload\/([^\[|^\\|^\/]+)\[\/[^\]]+\])|(?:(?:href|src)=””{0,1}[^\s|^””|^>|^’]*upload\/([^\s|^>]+)[“”|>|\s\’])” 
Set Matches = objRegExp.Execute(“[img]2312.jpg[/img][img]2312.jpg[/img]hh[img]http://www.dc9.cn/cm/upload/2ed312.jpg[/img] href=””http://www.dc9.cn/dccdd.jpg””>[IMG_RIGHT=400,300,title]upload/2assas.jpg[/IMG_RIGHT]”)
Dim TmpMatch
For i=0 to Matches.Count-1
Call InsertDataToArray(Matches(i).SubMatches(0),aryMatch)
Call InsertDataToArray(Matches(i).SubMatches(1),aryMatch)
Next

For i=0 to Ubound(aryMatch)
If Not IsNull(aryMatch(i)) And Trim(aryMatch(i))”” Then Response.write aryMatch(i)&”
”
Next

Function InsertDataToArray(Data,ByRef aryMatch)
If Trim(Data)”” Then
Data=Replace(Data,”‘”,””)
Data=Replace(Data,””””,””)
Redim Preserve aryMatch(Ubound(aryMatch)+1)
ZC_UPLOAD_MATCH=False
For j=0 to Ubound(aryMatch)
If aryMatch(j)=Data Then ZC_UPLOAD_MATCH=True
Next
If Not ZC_UPLOAD_MATCH Then aryMatch(Ubound(aryMatch))=Data
End If
End Function

PS:最近正则又精进不少…
