Mike McGann updated DAFFODIL-2205:
----------------------------------
Description:
This bug report is based on a message Roger Costello posted to the Daffodil
Users group.
>From the DFDL specification, when emptyValueDelimiterPolicy is set to 'none':
{quote}'none' indicates that if the content region is empty neither the
dfdl:initiator or dfdl:terminator must be present. On unparsing when
the content region is empty nothing will be output.
{quote}
Based on the above, if in the schema an element has an initiator and a
terminator, and if the emptyValueDelimiterPolicy is set to 'none', to represent
an empty value neither the initiator nor the terminator should be present in
the input.
In the attached test case,
* the element *MiddleName* has an initiator and a terminator
* *emptyValueDelimiterPolicy* is set to 'none'
* For the test input, John,,Doe we are getting the parse error: [error] Parse
Error: Found out of scope delimiter: ',' ','
* Test input John,(),Doe parses successfully
{code:xml}
<xs:element name="input">
<xs:complexType>
<xs:sequence
dfdl:separator=","
dfdl:separatorPosition="infix"
dfdl:separatorSuppressionPolicy="trailingEmpty">
<xs:element
name="FirstName"
type="xs:string" />
<xs:element

dfdl:initiator="("
dfdl:terminator=")"
dfdlx:emptyElementParsePolicy="treatAsEmpty"
dfdl:emptyValueDelimiterPolicy="initiator" />
<xs:element
name="LastName"
type="xs:string" />
</xs:sequence>
</xs:complexType>
</xs:element>
{code}
Input:
John,(),Doe – parse successful
John,,Doe – Parse error.
[error] Parse Error: Found out of scope delimiter: ',' ','
The files used for testing this scenario are attached.
It also appears that it does not work for 'initiator' and 'terminator' as well
so this ticket will be about implementing this feature instead of fixing a bug.
