Retrieving SPARQL-results xml using curl
Hello,
I use the last distribution of Fuseki which is initialized with a TDB2
dataset [1].
Working with the user interface, everything os working well. I mean I am
able to retrieve results from a select query and then download it.
Going one step further, I would like to automate dataset update and dataset
queries restitution.
I am able to run SPARQL Update query within culr (using SPARQL INSERT
inside a ttl file).
I am also able to get SPARQL Result JSON objects using commands line like
the following :
curl
http://localhost:3030/Metro/query?query=PREFIX+rdf%3A+%3Chttp%3A%2F%2Fwww.w3.org%2F1999%2F02%2F22[..
.]
However, if I specify the header to return XML result set, it keeps
outputting the data in a JSON format.
Here is my command : curl
http://localhost:3030/Metro/query?query=PREFIX+rdf%3A+%3Chttp%3A%2F%2Fwww.w3.org%2F1999%2F02%2F22[..
.] -X POST -H 'Accept:+application/sparql-results+xml'
I don't know what could be wrong. I am not an expert using curl... But
syntax that I have seen on forums looks like the same...
> Do you have an idea of what I am doing wrong?
Regards,
Brice
[1] there is a huge progress between TDB1 and TDB2 (also fuseki 1 and 2).
Thanks a lot to the community to make it available.

Thank you Martynas for the direct link & Jean-Marc for the wget method.
I was almost there ;-)
I have been using GET earlier on the morning :
curl -H "Accept: application/sparql-results+xml" -X GET http://[..]
But at this time, due to the call from a .bat file (windows), it has not
been successful because a wrong encoding format in the URL.
Problem is solved (until a deployment in a Linux environment ...) :)
Have a good day,
Brice

Here is a SPARQL query using wget :
wget --method=POST \
--body-data="query=SELECT * WHERE {?S ?P ?O} LIMIT 10" \
--header='Accept:application/sparql-results+xml' \
http://localhost:9000/sparql2

You're doing a POST request but supplying a URL query as if it was GET?
