I have an xml file with the following data
<?xml version="1.0" encoding="UTF-8"?>
<dataroot xmlns:od="urn:schemas-microsoft-com:officedata" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="NAMEDAYS.xsd" generated="2012-08-16T21:47:41">
<NAMEDAYS>
<DAY>1</DAY>
<MONTH>1</MONTH>
<NAMEDAY>New Years Day</NAMEDAY>
</NAMEDAYS>
<NAMEDAYS>
<DAY>6</DAY>
<MONTH>1</MONTH>
<NAMEDAY>Holly Spirit</NAMEDAY>
</NAMEDAYS>
The first element is the day then the month and finally the holiday.
I want to search the xml file for a specific day and month and return the holiday of that date.
Can you help me?
At first you have to create a sample class( for ex: MySampleClass) which will be used to store the XML element values and then you need to filter the data in a similar way:
XDocument loadedCustomData = XDocument.Load("CustomData.xml");
var filteredData = from c in loadedCustomData.Descendants("NAMEDAYS")
where c.Attribute("DAY").Value == "1" && c.Attribute("MONTH").Value == "1"
select new MySampleClass()
{
//set your properties here
};
listBox1.ItemsSource = filteredData;

I'm new to LINQ and am attempting to query an XML file by attribute and a descendant element value.
Here's a snip of my XML:
<redirurl>
<exceptionList state="FL">
<exception>
<plancode>ZZ</plancode>
<url>https://zzzz.com</url>
</exception>
</exceptionList>
<exceptionList state="NC">
<exception>
<plancode>AA</plancode>
<url>https://aaaa.com</url>
</exception>
<exception>
<plancode>BB</plancode>
<url>https://bbbb.com</url>
</exception>
</exceptionList>
</redirurl>
I'm trying to retrieve the value for url by state and plancode. For example, if the exceptionList state attribute = "NC" and the plancode = "BB", I want to get the url of "https://bbbb.com".
Here's my code:
var xmlFilePath = "myFilePathHere";
XElement xelement = XElement.Load(xmlFilePath );
IEnumerable<XElement> urlAddress = from el in xelement.Elements("exceptionList")
where (string)el.Attribute("state") == "NC"
&& (string)el.Element("exception").Element("plancode") == "BB"
select el;
I can't get the query right to save my life. If I omit the third line of the query (plancode line), I get the entire exceptionList node as a result. I suppose I could loop through it to get the plancode, but that doesn't seem like the right thing to do. The query as is does not return results. I've spent about 10 hours on this, doing tutorials and looking at code examples, but I'm just not getting it. Can someone advise what I'm missing? Thanks in advance.
Here is a Linq sequence that does as you ask:
XDocument doc = XDocument.Parse("<redirurl><exceptionList state=\"FL\"><exception><plancode>ZZ</plancode><url>https:////zzzz.com</url></exception></exceptionList><exceptionList state=\"NC\"><exception><plancode>AA</plancode><url>https:////aaaa.com</url></exception><exception><plancode>BB</plancode><url>https:////bbbb.com</url></exception></exceptionList></redirurl>");
var urlIWant = doc.Root.Descendants("exceptionList").Where(x => x.Attribute("state").Value == "NC").FirstOrDefault()
.Descendants("exception").Where(z => z.Descendants("plancode").FirstOrDefault().Value == "BB")
.FirstOrDefault().Descendants("url").FirstOrDefault().Value;
How to search for each file in a single directory of xml files and get value of one element?
I tried to loop in Linq:
var files = Directory.GetFiles(C:\Users\valen\Downloads\2019-11-04 apmt, "*.xml", SearchOption.AllDirectories);
foreach (var file in files) {
var doc = XDocument.Load(file);
I need to find shipment element in <>.
It is hard to help when there is very little information about your XML given in OP. Assuming you are searching for Element ShipmentId in your xml files, you could search the Xml File using Linq. For example,
var listOfShipmentIds = new List<string>();
var files = Directory.GetFiles(folderToSearch, "*.xml", SearchOption.AllDirectories);
foreach(var file in files)
{
var dataRead = XDocument.Load(file)
.Root
.DescendantNodes()
.OfType<XElement>()
.Where(x=>x.Name.LocalName.Equals("ShipmentId"))
.Select(x=>x.Value);
listOfShipmentIds.AddRange(dataRead);
}
This would enable you to parse the Xml files and get the value of Element specified.
I would like to know if its possible using Xpath to return mutliple elements from a single Xpath query without the use of the union '|' operator?
The problem I have is that I want to return two elements that are at different levels of the XML structure (employment_information.person_id_external and job_information.start_date) in one Xpath query from the following XML:
<CompoundEmployee>
<person>
<person_id_external>21554</person_id_external>
<employment_information>
<start_date>2014-02-27</start_date>
<job_information><end_date>2013-04-21</end_date><event>H</event><start_date>2012-09-28</start_date></job_information>
<job_information><end_date>2013-04-26</end_date><event>5</event><start_date>2013-04-22</start_date></job_information>
<job_information><end_date>9999-12-31</end_date><event>R</event><start_date>2014-02-27</start_date></job_information>
</employment_information>
</person>
<person>
<person_id_external>8265</person_id_external>
<employment_information>
<start_date>2000-10-02</start_date>
<job_information><end_date>2014-10-24</end_date><event>5</event><start_date>2014-05-22</start_date></job_information>
<job_information><end_date>2014-05-21</end_date><event>H</event><start_date>2000-10-02</start_date></job_information>
<job_information><end_date>9999-12-31</end_date><event>5</event><start_date>2014-10-25</start_date></job_information>
</employment_information>
</person>
<execution_timestamp>2015-05-05T08:17:51.000Z</execution_timestamp>
<version_id>1502P0</version_id>
</CompoundEmployee>
and the XPath query I've written so far is:
XPath x = XPath.newInstance("/*/*/*/job_information[number(translate(start_date,'-','')) < number(translate(../start_date,'-','')) and (event = 'H' or event = 'R')]/start_date");
Employees = x.selectNodes(doc);
for (Element Employee : Employees) {
fieldName = Employee.getName();
fieldValue = Employee.getText();
println ("Job Information Selection ${fieldName} = ${fieldValue}");
}
which works but only returns the job_information.start_date. If I union the same query but return employment_information.person_id_external the query returns them on two rows - 1 row per union but I want them returned on the same row but as two fields, if that makes sense. Can I do this? And if so how do I do it?
Thanks,
Greg
I need to get all activities for specific claim ID = 13 using linq C#, I am trying the below code, but it's not working.
XDocument Doc = XDocument.Load(DownloadedPath);
var Activites = (from e in Doc.Descendants("Activity")
where (string)Doc.Element("Claim").Element("ID") == 13
below is the Xml
<?xml version="1.0" encoding="utf-8"?>
<Advice>
<Claim>
<ID>12</ID>
<ProviderID>CL-MC-0012-07</ProviderID>
<Activity>
<ID>20131520320</ID>
<Start>24/07/2013 13:00</Start>
<Type>3</Type>
</Activity>
<Activity>
<ID>20131520321</ID>
<Start>24/07/2013 13:00</Start>
<Type>3</Type>
</Activity>
</Claim>
<Claim>
<ID>13</ID>
<ProviderID>CL-MC-0012-07</ProviderID>
<Activity>
<ID>20132058590</ID>
<Start>20/10/2013 09:00</Start>
<Type>3</Type>
</Activity>
<Activity>
<ID>20132058591</ID>
<Start>20/10/2013 09:00</Start>
<Type>3</Type>
</Activity>
</Claim>
You're currently converting the value to a string but then comparing it with an int. Don't do that - it's not going to work :)
It's probably simplest to convert it to an int instead:
var Activites = (from e in Doc.Descendants("Activity")
where (int)Doc.Element("Claim").Element("ID") == 13
...)
Next, look at your XML - the Claim element isn't inside an Activity element... you probably just want:
var activities = doc.Descendants("Claim")
.Where(claim => (int) claim.Element("ID") == 13)
.SelectMany(claim => claim.Elements("Activity"));
This finds all Claim elements with an ID of 13 (of which there will probably only be one) and then selects its activities, using SelectMany so that the result will be a sequence of activity elements, rather than a sequence of sequences...
I have the following xml string:
<report>
<item id="4219" Co="6063" LastName="Doe" FirstName="John"/>
<item id="2571" Co="6063" LastName="Doe" FirstName="Jane"/>
</report>
How do I write a Linq to xml query that filters by name = "Jane" and writes it back to a xml string
I have the following code so far:
XDocument reportXmlDoc = XDocument.Parse(_report); //This is the string var assigned with data above
var filteredList = from x in fullReportXmlDoc.Descendants("item")
where x.Attribute("FirstName").Value == "Jane"
select x;
How do I convert filteredList back to a xml string?
You can project a new XML tree from your existing query:
var filteredList =
from x in fullReportXmlDoc.Descendants("item")
where x.Attribute("FirstName").Value == "Jane"
select new XElement("report", x).ToString();
Or maybe, in a more general case:
string result = new XElement("report",
from x in fullReportXmlDoc.Descendants("item")
where x.Attribute("FirstName").Value == "Jane"
select x).ToString();
Have you tried using SaveOptions.DisableFormatting to get the XElement's XML string? It would look something like this for your case:
XDocument reportXmlDoc = XDocument.Parse(_report); //This is the string var assigned with data above
var elementStrings = from x in fullReportXmlDoc.Descendants("item")
where x.Attribute("FirstName").Value == "Jane"
select x.ToString(SaveOptions.DisableFormatting);
