It's really the alt or title tag that might potentially have non-xml safe characters, but still not very often. The 2nd rereplace checks to see if the image has an xml closing and if not then it closes it so that the xmlparse() will work properly. Of course, if you don't want to do the xml thing, once you have the tag by itself, then it's a lot easier to just get the src attribute via regex,i.e. Although that runs some other potential risks of getting content from a site that's using xml where the author used single-quotes instead of doublequotes (minor change to the above regex I admit). I'm just saying, 6 of 1, 1/2-doz of the other there are a number of potential points of failure either way. hth, ike -- s. isaac dealey ^ new epoch isn't it time for a change? ph: 503.236.3691 http://onTap.riaforge.org ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:295227 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4

Re: Another RegEx question...
The first thing I see is that you are only allowing for single-character names. You don't have a + or * (+ would be better) after [a-z0-9_].

RE: Another RegEx question
This snippet will parse a variable called file and create a list with
all URLs called lURL (pipe delimited)
regexp = 'href[[:space:]]*=[[:space:]]*"[^"]"';
cnt = REFindNoCase(regexp,file,1,"yes");
while (cnt.pos[1] GT 0) {
text = mid(tmpvar,cnt.pos[2],cnt.len[2]);
text = ListLast(text,"/");
// the next if is only required if you dont want duplicate urls
if(NOT ListFind(lURL,text,"|"))
lURL = ListAppend(lURL,text,"|");
cnt = REFindNoCase(variables.regexp,tmpvar,cnt.pos[2],"yes");
