This is something you can't do (easily) with regexp. The text means
anything except the characters < / s p a n >. Remember that that []
matches a SINGLE character. If you want to remove empty span tags, do it
in 4 steps:
1. find empty span tag (no regexp needed)
2. remove it
3. find matching end tag (note that span tags can be nested, so it is
not necessarily the next </span>)
4. remove it
<cfscript>
function RemoveSpan(text){
var start1 = 1;
var start2 = 1;
var pos = 0;
var stTmp = StructNew();
var cnt = 0;
while(true){
// find empty span
pos = FindNoCase("<span>",text,start1);
if(NOT pos) break;
// remove empty span tag
text = RemoveChars(text,pos,Len("<span>"));
// find matching end tag
cnt = 1;
start2 = pos;
start1 = pos;
while(true){
stTmp =
REFindNoCase("</?span[^>]*>",text,start2,true);
if(NOT stTmp.pos[1]) break;
start2 = stTmp.pos[1] + stTmp.len[1];
if(Mid(text,stTmp.pos[1]+1,1) IS "/") cnt = cnt
- 1;
else cnt = cnt + 1;
if(cnt IS 0){
// remove matching end tag
text =
RemoveChars(text,stTmp.pos[1],stTmp.len[1]);
break;
}
}
}
return text;
}
</cfscript>
