Problem with (automatic or not) field extraction

[a_naoum]

Hi guys,

I have this case. Structured (more or less) data, KV pairs with '=' and divided with tabs.

Case 1 (automatic KV):
All good except two fields which contains urls. If the urls have '&' and after that KV pairs (typical for pages with fields) then all the data after the first '&' is been divided to fields (ex. url=koko.com/kokokok.php?oko&a=oooo&b=pooo) In the example I will have extracted fields url, a and b.

Case 2 (no automatic KV, use of DELIMS = "\t", "=" only)
All good except the two fields which contains urls. If the urls have '&' they are just simple disappeared. They are not extracted.

So it is possible somehow to get the urls corrected and regardless of the '&' with one way or another?

thanks!
