I am using Linq to to parse an XML, but it return no result:
XML:
<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
<downloadInfoResponse xmlns="http://webService">
<downloadInfoReturn>
<city>city</city>
<companyName>company name</companyName>
</downloadInfoReturn>
</downloadInfoResponse>
</soapenv:Body>
</soapenv:Envelope>
Code:
public class Merc
{
public string CompanyName { get; set; }
}
using (XmlReader reader = XmlReader.Create(new StringReader(result)))
{
XDocument doc = XDocument.Load(reader, LoadOptions.SetLineInfo);
List<Merc> m = (from downloadInfoReturn in doc.Descendants("downloadInfoReturn")
select new Merc
{
CompanyName = downloadMerchantInfoReturn.Element("companyName").Value
}).ToList();
}
Is there any other good method to do it? Thank you.
Your XML file contains namespaces thus you need to specify it when perform querying:
XNamespace xn = "http://webService";
doc.Descendants(xn + "downloadInfoReturn")
Because you are missing the namespace while querying the xml, also your class name doesn't match, try the following code, it works on my side.
List<Merc> m = null;
XNamespace ns = "http://webService";
using (XmlReader reader = XmlReader.Create(new StringReader(result)))
{
XDocument doc = XDocument.Load(reader, LoadOptions.SetLineInfo);
m = (from downloadInfoReturn in doc.Descendants(ns + "downloadInfoReturn")
select new Merc
{
CompanyName = downloadInfoReturn.Element(ns+ "companyName").Value
}).ToList<Merc>();
}
Console.WriteLine(m.Count); // this will show 1

I have an XML document with ISO-8859-1 encoding.
I can load the XML with XDOCUMENT, but i can't storage a specific node.
Can somebody help me with this?
The xml:
<?xml version="1.0" ?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<TERMEKADATOutput xmlns="http://xmlns.oracle.com/orawsv/PUPHAX/PUPHAXWS">
<RETURN>
<OBJTERMEKADAT>
<TTT>210037069</TTT>
<TK>OGYI-T-04617/05</TK>
</OBJTERMEKADAT>
</RETURN>
</TERMEKADATOutput>
</soap:Body>
</soap:Envelope>
And the code:
XDocument xmlDoc = null;
using (StreamReader oReader = new StreamReader(#"C:\Users\maruzsama\source\repos\EPPuphax\EPPuphax\asd.xml", Encoding.GetEncoding("ISO-8859-1")))
{
xmlDoc = XDocument.Load(oReader); //this working fine
var result = from q in xmlDoc.Descendants("OBJTERMEKADAT")
select new
{
asd = q.Element("TTT").Value
};
Console.ReadKey();
}
I need the data from the TTT node (210037069)
Try following changes :
XDocument xmlDoc = null;
using (StreamReader oReader = new StreamReader(#"C:\Users\maruzsama\source\repos\EPPuphax\EPPuphax\asd.xml", Encoding.GetEncoding("ISO-8859-1")))
{
xmlDoc = XDocument.Load(oReader); //this working fine
XElement TERMEKADATOutput = xmlDoc.Descendants().Where(x => x.Name.LocalName == "TERMEKADATOutput").First();
XNamespace ns = TERMEKADATOutput.GetDefaultNamespace();
var result = from q in TERMEKADATOutput.Descendants(ns + "OBJTERMEKADAT")
select new
{
asd = q.Element(ns + "TTT").Value
};
Console.ReadKey();
}
I'm trying to get the element values of the following XML document using LINQ but I'm getting "Object reference not set to an instance of an object.";

I'm using the following to loop through:
using (StreamReader rd = new StreamReader(services.GetResponseStream()))
{
var ServiceResult = rd.ReadToEnd();
XDocument xdoc = new XDocument();
xdoc = XDocument.Parse(ServiceResult);
var xDocResult = (from x in xdoc.Descendants("Contacts")
select new Location
{
Address = x.Element("Address").Value,
Address2 = x.Element("Address2").Value,
city = x.Element("City").Value,
statecode = x.Element("StateCode").Value,
zipcode = x.Element("ZipCode").Value
});
}
I'm assuming it's because there is no root. How do I get the values of the individual elements?
Your xml has lots of errors. I'm using StringReader. You should replace with StreamReader. Here is correction

I have xml format as below. And trying to read elements from content, product name and product id but unable to. Here is what I have tried so far but no luck. Both of my approaches are not working any help is appreciated.
<source xml:base="https://google.com/api/v1" xmlns="http://www.w3.org/2005/Atom" >
<id>s1</id>
<value>
<id>value1</id>
<version>1.90</version>
<content type="application/xml">
<x:products>
<n:Productname>3M</n:Productname>
<n:ProductId n:type="Int32">97</n:ProductId>
</x:products>
<x:products>
<n:Productname>HD</n:Productname>
<n:ProductId n:type="Int32">99</n:ProductId>
</x:products>
</content>
</value>
</source>
FileStream fs = new FileStream(xmlFile, FileMode.Open, FileAccess.Read);
XmlDocument xmldoc = new XmlDocument();
XmlNodeList xmlnodecontent;
xmldoc.Load(fs);
xmlnodecontent = xmldoc.GetElementsByTagName("content");
for (int i = 0; i < xmlnodecontent.Count; i++)
{
var innerXml =xmlnodecontent[i].ChildNodes.Item(0).InnerXml;
//Trying to read product here
}
//Second approach
var doc = XDocument.Load(xmlFile);
var units = from u in doc.Descendants("value")
select new
{
Id = (int)u.Element("id"),
content = from entry in doc.Descendants("content")
select new
{
product = (int)u.Element("d:Product"),
}
};
foreach (var unit in units)
{
var id = unit.Id;
var content = unit.content;
}
I corrected the xml file and used xml linq (XDocument) to get values
<source xml:base="https://google.com/api/v1" xmlns="http://www.w3.org/2005/Atom" xmlns:x="abc" xmlns:n="def" >
<id>s1</id>
<value>
<id>value1</id>
<version>1.90</version>
<content type="application/xml">
<x:products>
<n:Productname>3M</n:Productname>
<n:ProductId n:type="Int32">97</n:ProductId>
</x:products>
<x:products>
<n:Productname>HD</n:Productname>
<n:ProductId n:type="Int32">99</n:ProductId>
</x:products>
</content>
</value>
</source>
Here is the code :

XNamespace ns = value.GetDefaultNamespace();
XNamespace xNs = value.GetNamespaceOfPrefix("x");
XNamespace nNs = value.GetNamespaceOfPrefix("n");
var values = doc.Descendants(ns + "value").Select(x => new
{
id = (string)x.Element(ns + "id"),
products = x.Descendants(xNs + "products").Select(y => new
{
name = (string)y.Element(nNs + "Productname"),
id = (string)y.Element(nNs + "ProductId")

I am trying to parse an XML response from a REST call. I can read the XML just fine with my stream reader but when I try to select the first node, it brings back nothing. Here is my XML:
<?xml version="1.0" encoding="UTF-8" standalone="true"?>
<slot_meta_data xmlns:ns2="http://www.w3.org/2005/Atom">
<product id="MDP">
<name>MDP</name>
</product>
<product id="CTxP">
<name>CTxP</name>
</product>
<product id="STR">
<name>STR</name>
</product>
<product id="ApP">
<name>ApP</name>
<slot>
<agent_id>-1111</agent_id>
<agent_name>ApP</agent_name>
<index_id>-1</index_id>
<alias>App Alias</slot_alias>
</slot>
</product>
<product id="TxP">
<name>TxP</name>
<slot>
<agent_id>2222</agent_id>
<agent_name>App2</agent_name>
<index_id>-1</index_id>
<alias>App2 Alias</slot_alias>
</slot>
</product>
</slot_meta_data>
Here is my code
string newURL = "RESTURL";
HttpWebRequest request = WebRequest.Create(newURL) as HttpWebRequest;
HttpWebResponse response = request.GetResponse() as HttpWebResponse;
StreamReader reader = new StreamReader(response.GetResponseStream());
XmlDocument xdoc = new XmlDocument();
xdoc.Load(response.GetResponseStream());
XmlNodeList list = xdoc.SelectNodes("/slot_meta_data[#*]");
foreach (XmlNode node in list)
{
XmlNode product = node.SelectSingleNode("product");
string name = product["name"].InnerText;
string id = product["id"].InnerText;
Console.WriteLine(name);
Console.WriteLine(id);
Console.ReadLine();
}
When I debug list, it has a count of 0.
Using xml linq
using System;
using System.Collections.Generic;

using System.Xml.Linq;

I have an XML looking like this:
<data xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<row>
<Alert>warning</Alert>
</row>
</data>
I wan't to get all the rows. In this case, the value that I wan't is "Alert".
This is as fare as I've got...
using (XmlReader reader = cmd.ExecuteXmlReader())
{
string xmlFile = "";
while (reader.Read())
{
xmlFile = reader.ReadOuterXml();
}
var xmlElement = XElement.Parse(xmlFile);
var result = xmlElement.Elements("data").Where(x => x.Value.Equals("row")).ToList();
}
I know something is wrong with my linq, but I'm quite new to linq and would like some help.
Thanks!
XNamespace ns = "http://www.w3.org/2001/XMLSchema-instance";
var xDocument = XDocument.Load("path");
var result = xDocument.Descendants(ns + "row").ToList();
I hope this will work. Please try this.
var xDocument = XDocument.Load(#"XmlFilePath");
//Use below if you have xml in string format
// var xDocument = XDocument.Parse("XmlString");
XNamespace ns = xDocument.Root.GetDefaultNamespace();
var result = xDocument.Descendants(ns + "row").ToList();
