I want to grab UPC value from the following XML example node, but the current doc.SelectNodes fails to grab that value. I am using XmlDocument to process my XML. Can you fix my code to grab UPC value? What am I doing wrong here?
C# Code:
string responseStr = new StreamReader(responseStream).ReadToEnd();
responseStream.Flush();
responseStream.Close();
XmlDocument doc = new XmlDocument();
doc.LoadXml(responseStr);
if (doc.GetElementsByTagName("Ack").Item(0).InnerText != "Failure")
{
string UPC = doc.SelectNodes("Item").Item(0).SelectNodes("UPC").Item(0).InnerText;
}

You have a namespace that must be used to get values. Here is the easy way using xml linq :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
namespace ConsoleApplication1
{
class Program
{
const string FILENAME = #"c:\temp\test.xml";
static void Main(string[] args)
{
XDocument doc = XDocument.Load(FILENAME);
XNamespace ns = doc.Root.GetDefaultNamespace();
string UPC = (string)doc.Descendants(ns + "UPC").FirstOrDefault();
}
}
}
If you have nulls use this
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
namespace ConsoleApplication1
{
class Program
{
const string FILENAME = #"c:\temp\test.xml";
static void Main(string[] args)
{
XDocument doc = XDocument.Load(FILENAME);
XNamespace ns = doc.Root.GetDefaultNamespace();
var upcs = doc.Descendants(ns + "UPC");
if (upcs != null)
{
string upc = (string)upcs.FirstOrDefault();
}
}
}
}

I have the following xml
<lists>
<list Group="3">More_lists_go_here</list>
</lists>
What I want is both the list element value which is More_lists_go_here and the Group attribute value which is 3.
What I have tried so far is
XmlDocument doc = new XmlDocument();
doc.LoadXml("<list Group=\"3\">More_lists_go_here</list>");
XmlElement root = doc.DocumentElement;
string value = root.Descendants("lists").Elements("list").Select(x => (string)x.Attribute("Group")).ToList();
what that gets me is
value = 3
what I want is both 3 and More_lists_go_here for string value
Use xml linq :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
namespace ConsoleApplication40
{
class Program
{
const string FILENAME = #"c:\temp\test.xml";
static void Main(string[] args)
{
string input = "<lists><list Group=\"3\">More_lists_go_here</list></lists>";
XDocument doc = XDocument.Parse(input);
var results = doc.Descendants("list").Select(x => new { group = (string)x.Attribute("Group"), value = (string)x }).ToList();
}
}
}
I have an XML with this structure:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns2:Dossiers xmlns:ns2="http://www.dat.de/vxs" source="SD3" type="completeEvaluation">
<ns2:Dossier>
<ns2:Vehicle>
<ns2:VehicleIdentNumber>aaaaaaaaaa</ns2:VehicleIdentNumber>
<ns2:Equipment>
<ns2:OriginalEquipmentValueGross origin="dat">16206.00</ns2:OriginalEquipmentValueGross>
<ns2:SeriesEquipment>
<ns2:EquipmentPosition>
<ns2:DatEquipmentId>15201</ns2:DatEquipmentId>
<ns2:Description>lorem ipsum</ns2:Description>
</ns2:EquipmentPosition>
<ns2:EquipmentPosition>
<ns2:DatEquipmentId>17602</ns2:DatEquipmentId>
<ns2:Description>lorem ipsum</ns2:Description>
</ns2:EquipmentPosition>
...
</ns2:SeriesEquipment>
</ns2:Vehicle>
<ns2:Vehicle>
....
</ns2:Vehicle>
</ns2:Dossier>
</ns2:Dossiers>
With this code I have obtained the ns2:VehicleIdentNumber value:
XmlDocument xml = new XmlDocument();
xml.LoadXml(xmlFileContent);
var xmlNodeList = xml.GetElementsByTagName("ns2:Vehicle");
foreach (XmlElement xmlElement in xmlNodeList)
{
var telaio = xmlElement["ns2:VehicleIdentNumber"];
}
but how can I get ns2:OriginalEquipmentValueGross value and ns2:Description value?
Using Xml Linq :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
namespace ConsoleApplication1
{
class Program
{
const string FILENAME = #"c:\temp\test.xml";
static void Main(string[] args)
{
XDocument doc = XDocument.Load(FILENAME);
XElement root = doc.Root;
XNamespace ns2 = root.GetNamespaceOfPrefix("ns2");
var results = doc.Descendants(ns2 + "Vehicle").Select(x => new
{
vehicleIdentNumber = (string)x.Element(ns2 + "VehicleIdentNumber"),
originalEquipmentValueGross = (string)x.Descendants(ns2 + "OriginalEquipmentValueGross").FirstOrDefault()
}).ToList();
}
}
}
It should be more or less the same of what you already have:
var xmlNodeList = xml.GetElementsByTagName("ns2:Vehicle");
foreach (XmlElement xmlElement in xmlNodeList)
{
var telaio = xmlElement["ns2:VehicleIdentNumber"];
var equipment = xmlElement["ns2:Equipment"];
var originalEquipmentValueGross = equipment["ns2:OriginalEquipmentValueGross"].InnerText;
foreach (XmlElement equipmentPosition in equipment["ns2:SeriesEquipment"].GetElementsByTagName("ns2:EquipmentPosition"))
{
var description = equipmentPosition["ns2:Description"].InnerText;
}
}

So is it possible to do this? I had a go at doing this but I know for a fact i am doing it wrong as it cannot produce the result i want so any help will be much appreciated:
C# Code
XDocument doc = XDocument.Parse(xml);
XElement root = doc.Root;
XNamespace glsNs = root.GetNamespaceOfPrefix("gls");
XNamespace cnrNS = root.GetNamespaceOfPrefix("cnr");
XNamespace pbrNS = root.GetNamespaceOfPrefix("pbr");
var output = new StringBuilder();
foreach (var result in doc.Descendants(gls + "PatientDem").Select(x => new {
Key = (string)x.Name.LocalName,
Value = x.Value
}))
{
output.AppendLine($"{result.key} : {result.value}");
}
Try following :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Xml;
using System.Xml.Linq;
namespace ConsoleApplication108
{
class Program
{
const string FILENAME = #"c:\temp\test.xml";
static void Main(string[] args)
{
XDocument doc = XDocument.Load(FILENAME);
XElement root = doc.Root;
XNamespace cnrNs = root.GetNamespaceOfPrefix("cnr");
var results = doc.Descendants(cnrNs + "PatientId").Select(x => new {
value = (string)x.Element(cnrNs + "IdValue"),
scheme = (string)x.Element(cnrNs + "IdScheme")
}).ToList();
}
}
}
I have the following XML
<User
xmlns:i="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://schemas.datacontract.org/2004/07/GaryLeaderboardsAPI.Models">
<Game_ID>3</Game_ID>
<UserGUID>e00d3560-4133-4ba6-8bba-e6c8659468b4</UserGUID>
<UserName>tony2</UserName>
<User_ID>16</User_ID>
</User>
Using C# I am loading this into an XMLDocument, How do I retrieve the UserGUID value?
Leveraging System.Xml.Linq you could do
string xml = "..."; // your inline XML
var doc = System.Xml.Linq.XDocument.Parse(xml);
or
string xmlFile = "..."; // your XML filename
var doc = System.Xml.Linq.XDocument.Load(xmlFile);
and then, to get the UserGUID
var userGuid = doc.Descendants().Where(x=>x.Name.LocalName == "UserGUID").First().Value;
This will work for you.
string xml = "<User xmlns:i=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns=\"http://schemas.datacontract.org/2004/07/GaryLeaderboardsAPI.Models\">" +
"<Game_ID>3</Game_ID>" +
"<UserGUID>e00d3560-4133-4ba6-8bba-e6c8659468b4</UserGUID>" +
"<UserName>tony2</UserName>" +
"<User_ID>16</User_ID>" +
"</User>";
XmlDocument doc = new XmlDocument();
doc.LoadXml(xml);
var id = doc.GetElementsByTagName("UserGUID")[0].InnerText;
You need to use the namespace. I often use mipnw approach (probably stole idea from one of my postings). See code below :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
namespace ConsoleApplication1
{
class Program
{
const string FILENAME = #"\temp\test.xml";
static void Main(string[] args)
{
XDocument doc = XDocument.Load(FILENAME);
XElement user = doc.Root;
XNamespace ns = user.GetDefaultNamespace();
string UserGUID = (string)user.Element(ns + "UserGUID");
}
}
}
I have the following method
string UpdateXmlString(string xmlString) {...}
I would like to find all tags which name contain password and delete a value;
Before:
<job xmlns:i=\"...\" xmlns=\"...">
<password>asdfasdf</password>
<adminPassword>asd</adminPassword>
...</job>
Expected result:
<job xmlns:i=\"..." xmlns=\"...">
<password></password>
<adminPassword></adminPassword>
...</job>
How to implement this method?
You should simply be using XmlDocument or XDocument to parse this. I wouldn't manipulate XML strings manually.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Xml;
using System.Xml.Linq;
namespace XDocumentTest
{
class Program
{
static void Main(string[] args)
{
try
{
String xml = "<?xml version=\"1.0\"?><rootElement>";
xml += "<user id=\"1\"><password>temp</password></user>";
xml += "<user id=\"2\"><adminPassword>foobar</adminPassword></user>";
xml += "<user id=\"3\"><somePassWORDelement>foobarXYZ</somePassWORDelement></user>";
xml += "</rootElement>";
XDocument doc = XDocument.Parse(xml);
foreach (XElement element in doc.Descendants().Where(
e => e.Name.ToString().ToLower().Contains("password")))
{
Console.WriteLine(element);
// Delete your value here. Either changing the text node
// or by removing the password node. E.g.
element.Value = string.Empty;
}
Console.WriteLine(doc.ToString());
}
catch (Exception e)
{
Console.WriteLine(e);
}
while (Console.ReadKey(true).Key != ConsoleKey.Escape)
{
}
}
}
}
You should use XPathNavigator.
In MSDN are some examples that will help you:
https://msdn.microsoft.com/en-us/library/zx28tfx1(v=vs.110).aspx
var doc = XDocument.Load(path);
var element = doc.Descendants("YOUR_Descendants")
.Where(arg => arg.Attribute("ExampleID").Value == "3" )//
.Single();
element.Element("UpdateElements")
.Element("UpdateElements_fc").Value = "222";// update
doc.Save(path); //save
