I'm new to the world of DFDL so I thought I'd have a go at parsing the Video Library Sample TDS message using DFDL instead of MRM.
On trying to deploy the BAR file containing the DFDL schema, I am getting the following error:
<CTDM2201E : DFDL property is not expected. Property 'dfdl:separator', object 'xsd:element #Borrowed'.'
If I run 'Test Parse Model' with the following input file:
{Name:[Title:Mr*FirstName:Fred*LastName:Bloggs]&Address:[HouseNo:12*Street:Willow Avenue*Town:Salisbury]&ID:P&PassportNo:J123456TT&Borrowed:[Fast Cars+2003-05-23+3.00]&Borrowed:[Cut To The Chase+2003-05-23+3.75]&Magazine:1}
all is well.
I'm running IBM Integration Bus version 9.0.0.2 on Windows (64 bit)
DFDL schema:

Looks like your setup for borrowed is not right.
| Code: |
| <xsd:element dfdl:initiator="Borrowed:[" dfdl:separator="&Borrowed:[" dfdl:terminator="]" dfdl:occursCountKind="implicit" maxOccurs="unbounded" name="Borrowed"> |
I'd have thought it should look like this:
| Code: |
| <xsd:element dfdl:initiator="Borrowed:[" dfdl:separator="&" dfdl:terminator="]" dfdl:occursCountKind="implicit" maxOccurs="unbounded" name="Borrowed"> |
Note the difference in the separator, but for all I care the separator should come from the preceding sequence, i.e. I would not have it on the element and at best the separator I would have on the element would be for it's subfields i.e. "+", but then you're going to put that on the following sequence.... so... how did you build the model? with the DFDL graphical model builder?
Have fun

Inserting an extra sequence - as alluded to in your reply - did the trick, see below:
| Code: |
<xsd:element name="Borrowed">
<xsd:complexType>
<xsd:sequence dfdl:separator="&">
<xsd:element dfdl:initiator="Borrowed:[" dfdl:terminator="]" dfdl:occursCountKind="implicit" maxOccurs="unbounded" name="BorrowedRec">
<xsd:complexType>
<xsd:sequence dfdl:separator="+">
<xsd:element dfdl:lengthKind="delimited" name="VideoTitle" type="xsd:string"/>
<xsd:element dfdl:lengthKind="delimited" name="BorrowedDate" type="xsd:string"/>
<xsd:element dfdl:lengthKind="delimited" name="Charge" type="xsd:string"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:sequence>
</xsd:complexType>
</xsd:element> |
This generates the following XML for 'Borrowed' :
| Code: |
<Borrowed>
<BorrowedRec>
<VideoTitle xsi:type="xs:string">Fast Cars</VideoTitle>
<BorrowedDate xsi:type="xs:string">2003-05-23</BorrowedDate>
<Charge xsi:type="xs:string">3.00</Charge>
</BorrowedRec>
<BorrowedRec>
<VideoTitle xsi:type="xs:string">Cut To The Chase</VideoTitle>
<BorrowedDate xsi:type="xs:string">2003-05-23</BorrowedDate>
<Charge xsi:type="xs:string">3.75</Charge>
</BorrowedRec>
</Borrowed> |
It seems you can't put a 'separator' on anything but a 'sequence', although the previous version of the toolkit DID allow you to put a 'separator' on an 'element', but then through it out on deploying the BAR file.
One final question, is there any way to generate 2 occurrences of 'Borrowed' without the further level of 'BorrowedRec'? |

Correct - the DFDL specification says so.

I think that would require you to set maxOccurs>1 on a sequence group. DFDL does not allow sequence or choice groups to repeat.
