I have a peace of xml which I need to gather information off.
<response>
<students>
<student>
<educationalinstitutionname>Test One</educationalinstitutionname>
<academicqualificationtype>TestLevel One</academicqualificationtype>
<starttime>22/02/06</starttime>
<endtime>19/08/10</endtime>
<grade>A</grade>
</student>
<student>
<educationalinstitutionname>Test One</educationalinstitutionname>
<academicqualificationtype>TestLevel Two</academicqualificationtype>
<starttime>22/02/06</starttime>
<endtime>19/08/10</endtime>
<grade>B</grade>
</student>
<student>
<educationalinstitutionname>Test Two</educationalinstitutionname>
<academicqualificationtype>TestLevel Two</academicqualificationtype>
<starttime>22/02/06</starttime>
<endtime>19/08/10</endtime>
<grade>C</grade>
</student>
<student>
<educationalinstitutionname>Test Two</educationalinstitutionname>
<academicqualificationtype>TestLevel Three</academicqualificationtype>
<starttime>22/02/06</starttime>
<endtime>19/08/10</endtime>
<grade>D</grade>
</student>
</students>
The issue which I am having is that I need to parse the educationalinstitutionname once if it the same but gather the academicqualificationtype, starttime, endtime and grade for everything that it appears under the same educationalinstitutionname node.
XmlNodeList WordXMLNodeLists = XmlResponceDoc.SelectNodes("/response/students/student");
string GetDetaisl = string.Empty;
foreach (XmlNode GradeItem in WordXMLNodeLists)
{
string GetStartDate = EducationElement.SelectNodes("/response/students/student/starttime")[0].InnerText;
string GetEndDate = EducationElement.SelectNodes("/response/students/student/endtime")[0].InnerText;
string GetEstablishmentName = EducationElement.GetElementsByTagName("educationalinstitutionname")[0].InnerText;
string GetGrade = EducationElement.SelectNodes("/response/students/student/grade")[0].InnerText;
GetDetaisl = string.Concat(GetStartDate, " ", GetEndDate, " ", GetEstablishmentName);
if (GetDetaisl.Length == GetEstablishmentName.Length)
{
string GetGrades = GetGrade;
GetEducationNodeDate.Add(GetGrades);
}
else
{
GetEducationNodeDate.Add(GetDetaisl);
continue;
}
}
The issue which I am finding is that I cannot seem to loop through the name once and gather all the information in the document under that name for the establishment. Thanks for any help which you can provide
It isn't very clear what you're trying to achieve specifically. I assumed that basically you want value of most of nodes within <student> tag :
XmlNodeList WordXMLNodeLists = XmlResponceDoc.SelectNodes("/response/students/student");
foreach (XmlNode GradeItem in WordXMLNodeLists)
{
string GetStartDate = GradeItem.SelectSingleNode("./starttime").InnerText;
string GetEndDate = GradeItem.SelectSingleNode("./endtime").InnerText;
string GetEstablishmentName = GradeItem.SelectSingleNode("./educationalinstitutionname").InnerText;
string GetGrade = GradeItem.SelectSingleNode("./grade").InnerText;
//do something with data gathered above
}

**Above is the XML code and I'm trying to sort it in order of age using linq so it should be able to display name and age in order at the end.
Code below is showing error. Would appreciate it if someone could give me input on this.
I'm actually still learning right now and was trying out stuff but obviously it is not working. **
XDocument studentsXdoc1 = new XDocument();
studentsXdoc1 = XDocument.Parse(studentsXML);
var testing = from student in studentsXdoc1.Descendants("Student")
orderby student.Element("Age")
select new
{
Name = student.Element("Name"),
Age = student.Element("Age")
};
foreach(var i in testing)
{
Console.WriteLine(i);
}
Console.ReadKey();
Just add .Value to student.Element("Age") to get the value of the element
var testing = from student in studentsXdoc1.Descendants("Student")
orderby int.Parse(student.Element("Age").Value)
select new
{
Name = student.Element("Name").Value,
Age = student.Element("Age").Value
};
The value of age needs to be parsed when ordering by age.
Let me put the scenario:
If the 'Student' node has same child elements then merge the 'Student' node. In this case if the 'Name' node is found in other 'Student' nodes with same value then those 2 'Student' nodes need to be merged with unique elements. In this case the 'Name' node being identical comes 1 time and the 'Address' node coming 2 times.
Also the input xml can have different set of child nodes and can have different names every time.
Below is Input xml
<Root>
<Student>
<Name>Tim</Name>
<Address>
<City>
<Location1>MEL</Location1>
</City>
</Address>
</Student>
<Student>

This is horrible code, and I haven't had time to clean it up, but this works.

I am attempting to get the value of a specific node for each parent element found.
In the example I want to return each students First Name.
Instead I am getting the first elements name in each instance. The InnerText of a Student is correct but the InnerText of FirstName is always Alex.
var xml = #"<School>

<Student>

<LastName>Smith</LastName>

<Grade>12</Grade>

var doc = new XmlDocument();
doc.LoadXml(xml);
var resourceTypeNodes = doc.GetElementsByTagName("Student");
var resourceTypesIterator = resourceTypeNodes.GetEnumerator();
while (resourceTypesIterator != null && resourceTypesIterator.MoveNext())
{
var resourceTypeNode = resourceTypesIterator.Current as XmlNode;
var typeNameElement = resourceTypeNode.SelectSingleNode("//FirstName");
Console.WriteLine(resourceTypeNode.InnerXml);
Console.WriteLine(typeNameElement.InnerText);
}
This is the output of the above code.
<FirstName>Alex</FirstName><LastName>Smith</LastName><Grade>11</Grade>
Alex
<FirstName>Joanne</FirstName><LastName>Robins</LastName><Grade>12</Grade>
Alex
<FirstName>Steve</FirstName><LastName>Baker</LastName><Grade>11</Grade>
Alex
What am I missing?
Because you're using //FirstName XPath expression, that will always return first node from root, it doesn't matter if you invoke on children. Just change this:
var typeNameElement = resourceTypeNode.SelectSingleNode("//FirstName");
To this:
var typeNameElement = resourceTypeNode.SelectSingleNode("FirstName");
Moreover is there any specific reason you're manually using IEnumerator? You may simplify your code with foreach:
foreach (XmlNode resourceTypeNode in doc.GetElementsByTagName("Student"))
{
var typeNameElement = resourceTypeNode.SelectSingleNode("FirstName");
Console.WriteLine(resourceTypeNode.InnerXml);
Console.WriteLine(typeNameElement.InnerText);
}
I want to search the tags in XML.
My XML is:-
<school>
<student>
<firstname>Vijay</firstname>
<lastname>Prabhu</lastname>
<age>27</age>
<photo>/NewExample;component/Images/icon_man.png</photo>
</student>
<student>
<firstname>Arun</firstname>
<lastname>Prasath</lastname>
<age>5</age>
<photo>/NewExample;component/Images/icon_man.png</photo>
</student>
<student>
<firstname>Satheesh</firstname>
<lastname>Kumar</lastname>
<age>27</age>
</student>
</school>
Here I want to check <photo> tag is available or not.
I have try like this.
var school= from ack in xdoc.Descendants("school")
select ack;
for(int i =0;i<school.count();i++)
{
if(school.ElementAt(i).Element("photo").Name.LocalName.Equals("photo"));
Console.WriteLine("Tag is available in==>"+i);
else
Console.WriteLine("Tag is Not available in==>"+i);
}
It is working. But when I use this same in another example with diff elements it showing error.
Please let me know any other effective way to search the Tags in c#.
Thanks in advance.
Get all students. Then try to retrieve photo element from student element. If it is equal to null then photo no exist in current student:
var students = xdoc.Root.Elements("student");
int i = 1;
string format = "Tag is {0}available in {1}";
foreach(var student in students)
Console.WriteLine(format, student.Element("photo") == null ? "not " : "",i++);
Output:
Tag is available in 1
Tag is available in 2
Tag is not available in 3
You can write extension to make code more readable
public static bool HasElement(this XElement parent, XName name)
{
return parent.Element(name) != null;
}
E.g. selecting all students which have photo will look like
from student in xdoc.Root.Elements("student")
where student.HasElement("photo")
select student
You also can use XPath for same task
xdoc.XPathSelectElements("school/student[photo]")
I have a simple xml of users. I have a StudentId, I just need to get the student name from the xml on the basis of studentid. Seems to be simple but I am unable to get it done using xpath.
Here's the xml:
<Students>
<Student>
<StudentId>1</StudentId>
<StudentName>Mad</StudentName>
</Student>
<Student>
<StudentId>2</StudentId>
<StudentName>Cad</StudentName>
</Student>
</Students>
Here's my code:
XDocument xmldoc = XDocument.Load(Server.MapPath("~/xmlsample.xml"));
string StudentId = "2"; // id to be selected
var username = xmldoc.XPathSelectElement("Students/Student/StudentName").Value;// Not sure how to use where condition here
You just need to filter by studentId. Should be:
var username = xmldoc.XPathSelectElement(String.Format("Students/Student[StudentId={0}]/StudentName", StudentId)).Value;
