Hi Folks,
The RFC for CSV says that every record in a CSV file should have the same
number of fields. That check is easily expressed in XPath:
every $i in *[position() gt 1] satisfies count($i/*) eq
count($i/preceding-sibling::*[1]/*)
So I added that XPath expression in an assert for the root element (csv):
<xs:element name="csv">
<xs:annotation>
<xs:appinfo source="http://www.ogf.org/dfdl/";>
<dfdl:assert test="{ every $i in *[position() gt 1] satisfies
fn:count($i/*) eq fn:count($i/preceding-sibling::*[1]/*) }"
message="{'Each record should contain the same number of
fields.'}" />
</xs:appinfo>
</xs:annotation>
...
But that yields this error message:
[error] Schema Definition Error: Unable to parse expression. Message: '}'
expected but '$' found
What is the correct way to implement the check that all records have the same
number of fields?
