文件名 正则表达式提取方法

答案：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]<a href=>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)&"<br>" 
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]<a href=>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)&"<br>" 
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...
