[basex-talk] Re: csv:parse header option not working in version 11.7

[Gunther Rademacher via BaseX-Talk]

Hi Martin,

sorry about that. CSV functionality had been worked on to integrate the new XQuery 4.0 CSV functions, and this 
change of behaviour had inadvertently slipped into 11.7. 

However the problem has been fixed recently, and the fix will go into 11.8.

See https://github.com/BaseXdb/basex/pull/2376 for the details.

Best regards,
Gunther

Hi BaseX team,

 

Has the “header” option on csv:parse changed between BaseX version 11.6 and 11.7?

 

Here is an example to illustrate what looks like a problem or change. Given a tab separated text file such as this:

 

aaaa      bbbb     cccc

a1          b1          c1

a2          b2          c2

 

This query uses the “header”: “yes” option on csv:parse which should map column names to element names.

 

"tsv-test.tsv" => file:resolve-path() => file:read-text() =>

  csv:parse(map{'separator': 'tab', 'header': 'yes'})

 

With some tries (at https://martin-honnen.github.io/cheerpj-basex-test/, shameless plug) I have found that 'header' : true() e.g.

  csv:parse(map{'separator': '&#9;', 'header': true()})

works in 11.7.

No idea whether that is an intended change but perhaps you can adapt your code.
