解析OWL文件并将其保存到列表

问题描述：

我的存储对象从我的本体保存到List中有问题。我在easy xml（非owl文件）上做了简单的例子，但现在我不知道如何才能为单身学生获取这些值。解析OWL文件并将其保存到列表

本体片段：

<Ontology /> 
. 
. //here are 250 lines of declarations etc 
. 
    <ClassAssertion> 
    <Class IRI="#Stacjonarny" /> 
    <NamedIndividual IRI="#Student_3" /> 
    </ClassAssertion> 
    <DataPropertyAssertion> 
    <DataProperty IRI="#student_id" /> 
    <NamedIndividual IRI="#Student_3" /> 
    <Literal datatypeIRI="http://www.w3.org/2001/XMLSchema#integer">3</Literal> 
    </DataPropertyAssertion> 
    <DataPropertyAssertion> 
    <DataProperty IRI="#imie" /> 
    <NamedIndividual IRI="#Student_3" /> 
    <Literal datatypeIRI="http://www.w3.org/2001/XMLSchema#string">Grzegorz</Literal> 
    </DataPropertyAssertion> 
    <DataPropertyAssertion> 
    <DataProperty IRI="#nazwisko" /> 
    <NamedIndividual IRI="#Student_3" /> 
    <Literal datatypeIRI="http://www.w3.org/2001/XMLSchema#string">Brzęczyszczykiewicz</Literal> 
    </DataPropertyAssertion> 
    <DataPropertyAssertion> 
    <DataProperty IRI="#wydział" /> 
    <NamedIndividual IRI="#Student_3" /> 
    <Literal datatypeIRI="http://www.w3.org/2001/XMLSchema#string">Matematyczno-przyrodniczy</Literal> 
    </DataPropertyAssertion> 
</Ontology>

我想取值形成“文字”标记，并把它们保存到列表student_3，4，5等为学生。

学生：

class Student 
{ 
    public int student_id { get; set; } 
    public string imie { get; set; } 
    public string nazwisko { get; set; } 
    public string wydzial { get; set; } 

    public Student(string imie, string nazwisko, string wydzial, int student_id) 
    { 
     this.student_id = student_id; 
     this.imie = imie; 
     this.nazwisko = nazwisko; 
     this.wydzial = wydzial; 
    } 
}

昨天我花了差不多半天排练，现在我有这样的事情：

class Pobierz 
{ 
    List<classes.Student> studenci = new List<classes.Student>(); 


    public void studentow() 
    { 

     XDocument xml = XDocument.Load("moja_ontologia.owl"); 

     studenci = from student in xml.Root.Descendants("DataPropertyAssertion") 
        where student.Attribute("NamedIndividual").Value.Equals("Student") 
        select new classes.Student 
        { 
         imie = student.Element("") 
        } 
    } 
}

（I was based on this）

在一个sentention：我怎样才能从“文字”标记中获取这些值？

此代码不会编译。没有空的构造函数为学生类，你不能分配一个LINQ查询声明为列表变量 –

你有看看https://github.com/bpellens/owldotnetapi –

@Sir Rufo 是的，我做了，但我需要做我自己的解析器，它是大学的小型项目。好吧，现在，当我有空的构造函数，并且我不会将查询分配给声明为List的变量（只是var studenci），那么结果是什么？ – Kliwer

答

您应该使用序列化&反序列化....

声明这个类（如果你要重建这个班，由例如，如果XML结构的变化，看here的@达米安 - Drygiel答案）：

而这个学生类：

public class Student 
{ 
    public Student() 
    { 
    } 

    public string IRI { get; set; } 
    public OntologyDataPropertyAssertionNamedIndividual Name { get; set; } 
    public string TypeIRI { get; set; } 
    public string Value { get; set; } 
}

，并使用此LINQ例如为让您的DATAS（如果你的数据都是到C： \ temp \ test.xml）：

XmlSerializer serializer = new XmlSerializer(typeof(Ontology)); 

StreamReader reader = new StreamReader(@"c:\temp\test.xml"); 
Ontology ontology = (Ontology)serializer.Deserialize(reader); 

var students = from student in ontology.DataPropertyAssertion 
       select new Student() 
       { 
        Name = student.NamedIndividual, 
        TypeIRI = student.Literal.datatypeIRI, 
        Value = student.Literal.Value, 
        IRI = student.DataProperty.IRI, 
       }; 

foreach (var item in students) 
{ 
    //Use here your list of students 
} 

reader.Close(); 

reader.Dispose();
