Hi,

I read in “RyanPierce-20010226-FIXandFIXMLTransitions.pdf” that each FIXML element contains one or more FIXMLMessage elements. what does this actually mean?Does it mean that we can send one or more transaction requests in the same FIXML element?

Thanks in advance

Hi Lavanya,

In page 69 of 91 of this pdf at

http://www.fixprotocol.org/documents/623/RyanPierce-20010226-FIXandFIXMLTransitions.pdf

“The FIXMLMessage element contains exactly one Header element and one
ApplicationMessage element”

The DTD for ApplicationMessage does not define Subgroup ( Advertisement | Indication | News | Email | QuoteReq | Quote | Order | NewOrderList | etc… ) of ApplicationMessage to be repeatable i.e. the (|) does not have a + after it. So you cannot send more than 1 FIX transactions in a single message.

For XML refer :-

Hi Mahesh,
Thanks for the response. accepted that a FIXMLMessage element can contain only one ApplicationMessage element. But that does clear my doubt regarding this sentence in “The FIXML element contains one or more
FIXMLMessage elements (note the +)” page 68 of http://www.fixprotocol.org/documents/623/RyanPierce-20010226-
FIXandFIXMLTransitions.pdf.

Thanks in advance

Yes, you are correct, a FIXML can contain one or more FIXMLMessage elements. So a single FIXML could contain multiple orders / multiple IOIs.

Can you please give me an example message of that kind which has more than 1 FIXMLMessage element in FIXML element.
