SELECT
FIXML.ID.value('/Pty/@ID','VARCHAR(20)') as 'PTY ID' ,
FIXML.ID.value('/Pty/@Src','VARCHAR(20)') as 'PTY Src',
FIXML.ID.value('/Instrmt/AID/@AltID','VARCHAR(20)') as 'AltID' ,
FIXML.ID.value('/Instrmt/AID/@AltIDSrc','VARCHAR(20)') as 'AltIDSrc'
FROM
@doc.nodes('/FIXML/AllocInstrctn') as FIXML(ID)
In the Query above I am trying to extract all the values for PTY ID, PTY SRC and AltID and AltIDSrc but the code is throwing error.
Please suggest.

A couple things:
1. < and > are not allowed in attribute values. Change all of the "<Unassigned>" values to "& lt;Unassigned& gt;" (remove the spaces between "&" and "lt" and "gt"... forum formatting fun...), and you'll get past the error you're seeing.
2. Your .nodes will only return a single node, the <AllocInstrctn/> node. It appears you want two different nodesets: all of the <Pty/> nodes, and all of the <Instrmt><AID/></Instrmt> nodes. These are unrelated in the source document, so a single resultset is rather hard to construct... which AltID should be in the row with Pty ID "NOEX"? Not seeing any relation, I wrote something that would return the two sets of data from a corrected (see point #1) XML source:
SELECT FIXMLPty.ID.value('(../@ID)[1]','VARCHAR(20)') AS 'Alloc ID',FIXMLPty.ID.value('(./@ID)[1]','VARCHAR(20)') AS 'PTY ID',
FIXMLPty.ID.value('(./@Src)[1]','VARCHAR(20)') AS 'PTY Src'
FROM @doc.nodes('/FIXML/AllocInstrctn/Pty') AS FIXMLPty(ID)
SELECT FIXMLAID.ID.value('(../../@ID)[1]','VARCHAR(20)') AS 'Alloc ID',
FIXMLAID.ID.value('(./@AltID)[1]','VARCHAR(20)') AS 'AltID',
FIXMLAID.ID.value('(./@AltIDSrc)[1]','VARCHAR(20)') AS 'AltIDSrc'
FROM @doc.nodes('/FIXML/AllocInstrctn/Instrmt/AID') AS FIXMLAID(ID)
