All the various solutions proposed seem so convoluted. Why not do the simple and obvious? Something like: dfdl:ignoreInitiatorCase="yes" dfdl:ignoreTerminatorCase="no" dfdl:ignoreSeparatorCase="no" dfdl:ignoreElementCase="yes" From: dfdl-wg-bounces@ogf.org [mailto:dfdl-wg-bounces@ogf.org] On Behalf Of Tim Kimber Sent: Thursday, June 20, 2013 5:34 AM To: dfdl-wg@ogf.org Subject: Re: [DFDL-WG] how to do mix of case sensitive and insensitive delimiters The other way to do this is - wrap the element in a group - set dfdl:ignoreCase to 'no' on the group. - set dfdl:ignoreCase to 'yes' on the element. - put the terminator on the group and the initiator on the element. Or the other way round if it works better that way. regards, Tim Kimber, DFDL Team, Hursley, UK Internet: kimbert@uk.ibm.com<mailto:kimbert@uk.ibm.com> Tel. 01962-816742 Internal tel. 37246742 From: Mike Beckerle <mbeckerle.dfdl@gmail.com<mailto:mbeckerle.dfdl@gmail.com>> To: dfdl-wg@ogf.org<mailto:dfdl-wg@ogf.org>, Date: 19/06/2013 23:42 Subject: [DFDL-WG] how to do mix of case sensitive and insensitive delimiters Sent by: dfdl-wg-bounces@ogf.org<mailto:dfdl-wg-bounces@ogf.org> ________________________________ I have a wierd case where the initiator wants to be case insensitive matching, but the terminator wants to be case sensitive. The only way I can think of dealing with this is to use the initiator, but handle the length via lengthKind='pattern' to grab the value, doing lookahead so it will stop before the terminator. Then an empty sequence with a case sensitive terminator to pick off that part of the data stream. -- Mike Beckerle | OGF DFDL Workgroup Co-Chair | Tresys Technology | www.tresys.com<http://www.tresys.com/> -- dfdl-wg mailing list dfdl-wg@ogf.org<mailto:dfdl-wg@ogf.org> https://www.ogf.org/mailman/listinfo/dfdl-wg Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.
