Short answer - It depends (doesn't it always :) ) Long answer, If I assume there is no relationship between the 5th occurence of something (A) and the 9th occurrence of "whatever" (B) then the answer is no - you probably cannot do it in one rule. The reason being is that you want parse to essentially go back and process the input a second time in order to find B. So, need to call parse once to find (A), again to find (B) and then just do a copy/part A B. If however, there is a relationship, like all 9 occurrences of "whatever" always follow A then yes you can probably do it in a single parse rule. So what you need to do to use parse is to identify the rules that the page structure follows - or at least a pattern that you can exploit. If you have a concrete example, it might help. Brett.

This is a multi-part message in MIME format. ------=_NextPart_000_0015_01C02E18.23B1EDD0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit okay maybe I was being too generic. Example, parsing a web page to locate the fifth table. This basically involves looking for the fifth occurrence of "<table>" and then the second occurrence of "</table>" (as there is an embedded table in one of the cells). <html> <body> <table></table> <table></table> <table></table> <table></table> <table> <tr> <td><table></table></td> </tr> </table> </body> </html> The content I'd like to be copied is "<tr><td><table></table></td></tr>" (don't ask why I'd want this) Hope that clears up what I'm trying to do. Cheers, Jamie

Hello [hopeless--eircom--net], Here's a parse rule that does the trick: my-table-rule: [ 4 [thru "<table>" thru "</table>"] 1 [thru "<table>" copy my-text [thru "</table>" to "</table>"]] to end ] to end isn't strictly nessesary, but will make parse return true if the text was succesfully copied.
