Changes

* <code>$csv?names?*</code> returns the names of all fields (if available)

* Return enumerated strings for all records:

for $record at $pos in $csv?records

return $pos || ". " || string-join($record?*, ', ')

The resulting representation consumes less memory than XML-based formats, and values can be directly accessed without conversion. Thus, it is recommendable for very large inputs and for efficient ad-hoc processing.

'''Input''' {{Code|addressbook.csv}}:

Name,First Name,Address,City

Huber,Sepp,Hauptstraße 13,93547 Hintertupfing

'''Query:'''

let $text := file:read-text('addressbook.csv')

return csv:parse($text, map { 'header': true() })

'''Result:'''

<csv>

<record>

</record>

</csv>

'''

'''Query:'''

let $options := map { 'lax': false() }

let $input := file:read-text('some-data.csv')

let $output := $input => csv:parse($options) => csv:serialize($options)

return $input eq $output

'''Example 3:''' Converts CSV data to XQuery and returns distinct column values:

'''Query:'''

let $text := ``[Name,City

Jack,Chicago

)

)

'''Result:'''

Distinct values:

* Name: Jack, John

* City: Chicago, Washington, New York
