Извлечение фактического значения из результатов sparql
Я использую dotnetrdf, чтобы написать запрос sparql, чтобы получить тип, идентификатор и объяснить атрибуты привода, сохраненные в моей онтологии. Я использую следующий запрос выбора.
"PREFIX AP0: <http://www.semanticweb.org/faiza/ontologies/2014/10/ActuatorProvider#> " +
"PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>" +
"PREFIX owl: <http://www.w3.org/2002/07/owl#>" +
"PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>" +
"PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>" +
"SELECT *"+
"WHERE {"+
"?Name rdf:type AP0:Actuating_Device."+
"?Name AP0:ActuatorID ?id."+
"?Name AP0:ActuatorExplain ?Explain."+
"?Name AP0:AcuatorCode "txtActuatorID.Text"}"

Я использую gridview в C# для отображения результатов в. Это дает мне результаты в этой форме

TemperatureControl^^http://www.w3.org/2001/XMLSchema#anyURI
SD01^^http://www.w3.org/2001/XMLSchema#anyURI
Как я могу удалить URI из результатов.

Ну, вы не показали полный пример, поэтому мы не можем сказать, как вы отображаете результаты SPARQL, поэтому сложно ответить на вашу конкретную проблему (потому что вы еще не указали ее!). Однако я могу попытаться дать некоторые общие указания.
Данные, которые вы видите, являются полной формой INode экземпляры, которые встречаются в каждом столбце, поэтому первое, что вам нужно сделать, если вы хотите получить доступ только к частям значения, - это получить в качестве фактического узла. Это можно сделать несколькими способами:
//Assuming your result row is in a variable r
//With Named Indexing
INode value = r["var"];
//With Indexing
INode value = r[0];
//With method
INode value = r.Value("var");
Выберите тот, который наиболее подходит для вашего варианта использования, когда у вас есть узел, мы можем проверить, какой это тип узла, и действовать соответственно:
String text;
switch (value.NodeType)
{
case NodeType.Literal:
// Cast to more specific ILiteralNode in order to extract just the text
// excluding the data type or language specifier if present
ILiteralNode lit = (ILiteralNode)value;
text = lit.Value;
break;
case NodeType.Uri:
// Case to more specific IUriNode in order to extract final segment of URI
IUriNode uri = (IUriNode)value;
// Depending on the URI format this might be in the Fragment,
// the last Path Segment or just the URI
text = !String.IsNullOrEmpty(uri.Uri.Fragment) ? uri.Uri.Fragment : (uri.Uri.Segments.Length > 0 ? uri.Uri.Segments[uri.Uri.Segments.Length - 1] : uri.Uri.ToString());
break;
default:
// For anything else default to ToString()
text = value.ToString();
}
// Now do what you want with the text
Возможно, вам придется заключить это в повторно используемый класс / метод в зависимости от того, где и как вам нужно его вызывать.
Обратите внимание, что если вы привязываете его к какому-либо элементу управления в приложении с графическим интерфейсом, то обычно есть способы настроить представление данных при сохранении фактических данных под капотом.
Добавление того, что я считаю лучшим решением:
просто используйте .AsValuedNode(), а потомAsInteger()или любая другая функция, которая дает вам предпочтительный тип значения, например:
//Assuming we have a Node in the variable n already
IValuedNode value = n.AsValuedNode();
//Get the integer value
int i = value.AsInteger();
Я считаю, что значительно лучше, чемswitch caseв ответе @RobV (престижность этого ответа, поскольку он привел меня в правильном направлении).
Я получил ответ, используя следующее в моем запросе
SELECT? Ind (str(?Name) как? Name) (str(? Объяснить) как? Объяснять) (str (? Id) как? Actid)
WHERE {.....}.
