Can you elaborate on the context of what you're trying to do here? Because stuff like this is generally much much simpler with either XPath or jQuery. For example, here's how XPath matches any td containing an img: //td[//img] And here's how jQuery does it: $j( 'td:has(img)' ) To do it with RegEx, you want something like this: (?ims)<td[^>]*>(?:[^/]|/(?!td>))*<img[^>]+>.*?</td> So yeah, if you really have a specific need to do it with RegEx, you can probably use that, but I'd generally go for either of the other two for any tag-based issue like this. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;203748912;27390454;j Archive: http://www.houseoffusion.com/groups/RegEx/message.cfm/messageid:1170 Subscription: http://www.houseoffusion.com/groups/RegEx/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.21
