sorry if english bad^^ question how data other time´s problem data 6:00 , don´t know how data 17:00 or 23:00

my code getting weather:

string xml; using (var webclient = new webclient()) {     xml = webclient.downloadstring(url); } xdocument doc = xdocument.parse(xml);  string wind = doc.xpathselectelement("/city/forecast/date/time/ws").value + " km/h"; 

my problem data 6:00 , don´t know how data 17:00 or 23:00

seems should have condition in xpath, ex.,

string wind = doc.xpathselectelement("/city/forecast/date/time[@value='17:00']/ws")                  .value + " km/h"; 

(see [@value='17:00'])

if want values can use xpathselectelement**s** said in comments.
