Re: XML-INTO allowmissing=yes unicode

Sean,

if they are defined as Unicode (UCS2 that nearly equals UTF-16) so all
fields
are DBCS since UTF-8 isn't supported in RPGLE or DB2.

UTF-8 is a little special because it shares x'00'-x'7F' with ASCII - all
other
characters are encoded in a 2 to 4 byte "UNIT" where UTF-16 has all
characters in a fixed 2 byte representation and UTF-32 has a fixed 4 byte
representation.

So when dealing with UTF-8 it has to be converted into EBCDIC or UCS2
in order to be read in the ROGLE program and/or stored in a DB2 table.

Henrik,

Yes, I realise hex 40 is blank in EBCDIC, but none of my fields are
defined as character. My fields are defined as Unicode. When I view the hex
value prior to the XML-INTO operation, the value is all 20s. After the
XML-INTO, the hex value is all 40s. But the XML-INTO is reading into a
Unicode field. Plus, the IBM documentation states that if the XML tag is
missing, and allowmissing=yes is used, the data will be the same value as
prior to the XML-INTO.

Testing for *BLANK or *BLANKS will make no difference.

You get x'40' because the UTF-8 is converted into EBCDIC where x'40'
is equalt to ASCII/UTF-8 x'20'

Try to change your test to *BLANKS

I have a XML document on the IFS. CCSID is 1208.
A cut-down version of the file may be...

<?xml version="1.0" encoding="UTF-8"?> <PURCHASEORDER> <HEADER>
<HEADERNOTES> </HEADERNOTES> </HEADER> </PURCHASEORDER>

...this structure is defined as follows...

<PURCHASEORDER> <HEADER> <HEADERNOTES> <POHDRNOTE></POHDRNOTE>
</HEADERNOTES> </HEADER> </PURCHASEORDER>

In the RPGLE, this is defined as follows: -
D PO DS Qualified Inz
D Dim( POIdxMax )
D Header...
D LikeDS( Header_t )
D Header_t...
D DS Qualified
D Based( Template )
D HeaderNotes...
D LikeDS( HeaderNotes_t )
D HeaderNotes_t...
D DS Qualified
D Based( Template )
D POHdrNote...
D 50c Inz
D Dim( POHdrNteIdxMax )
read as follows...

options = 'doc=file + path=Update/member/PurchaseOrder
+ case=any + allowextra=yes
+ allowmissing=yes';
xml-into PO %xml( xmlfile : options );

When the POHdrNote data is not present in the XML, I expect the
PO(x).Header.HeaderNotes.POHdrNote(x) data field to contain blanks.
However, when I look at the hex values of the field in debug, the hex
value is all 40s (I would expect hex values of all 20s for unicode ?).
When I test in the program whether the data is *Blank, the test gives
me the wrong result.
Why am I getting hex value of 40s rather than 20s when the data tags
are missing from the XML ?
Thanks.
