Use xml linq like code below :

using System.Xml.Linq;
namespace ConsoleApplication58
{
class Program

Update a specific node in XML using XmlDocument

I am new to managing XML, I've read a couple of articles but I'm confused when it comes to a specific XML that I am working on. Can someone help me with the right statement? I just want to update the value of the ListStart, but I am getting an error when compiling. I am updating that part by this:
XmlDocument soapEnvelopeDocument = new XmlDocument();
soapEnvelopeDocument.Load(#"path");
XmlNode myNode = soapEnvelopeDocument.SelectSingleNode("descendant::cet:GetListCustomElement[cet:GetListCustom/cet:ListID='101']");
soapEnvelopeDocument.LastChild.InnerText = sDate;
<soapenv:Header/>
<soapenv:Body>
<cet:GetListCustomElement>
<!--Zero or more repetitions:-->
<cet:GetListCustom>
<cet:ListID>101</cet:ListID>
<cet:ListStart>13.11.2020</cet:ListStart>
</cet:GetListCustom>
</cet:GetListCustomElement>
</soapenv:Body>
</soapenv:Envelope>```
You only supplied a piece of the xml without the namespaces. With Xml linq you can get the element without the namespaces. 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 = #"c:\temp\test.xml";
static void Main(string[] args)
{
XDocument doc = XDocument.Load(FILENAME);
XElement ListStart = doc.Descendants().Where(x => x.Name.LocalName == "ListStart").FirstOrDefault();
ListStart.SetValue("14.11.2020");
}
}
}

I need to read xml file data but due to attribute it does not work

i want to read xml file but due to Document node attribute it did not read file.
Code C#:
XmlDocument xmldoc = new XmlDocument();
xmldoc.Load(HttpContext.Server.MapPath("~/Content/Images/MMS-CREATE-ALLA-ALLAH2H1-23102018-000170-INP.xml"));
XmlNode settings = xmldoc.SelectSingleNode("Document[#xmlns='urn:iso:std:iso:20022:tech:xsd:pain.009.001.01']/MndtInitnReq/GrpHdr");
stu.BranchName = settings.SelectSingleNode("MsgId").InnerText;
XML FIle:
<?xml version="1.0" encoding="UTF-8"?>
<Document xmlns="urn:iso:std:iso:20022:tech:xsd:pain.009.001.01">
<MndtInitnReq>
<GrpHdr>
<MsgId>10005226074</MsgId>
<CreDtTm>2018-10-23T15:20:56</CreDtTm>
</GrpHdr>
</MndtInitnReq>
</Document>
You have a namespace that must be used to get the data. Try Xml Linq :
using System;
using System.Collections.Generic;
using System.Collections;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
namespace ConsoleApplication75
{
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 msgId = (string)doc.Descendants(ns + "MsgId").FirstOrDefault();
XElement xCreDtTm = doc.Descendants(ns + "CreDtTm").FirstOrDefault();
//will give 1/1/01 when null
DateTime CreDtTm = xCreDtTm == null ? new DateTime() : (DateTime)xCreDtTm;
}
}
}
I don't think loading this xml should be a problem. I verified that by loading the xml you posted in an XmlDocument object.
However I think, your xpath to get "settings" node should have xml namespace in all tags after Document.
So the xpath should be "/[local-name()='Document' and namespace-uri()='urn:iso:std:iso:20022:tech:xsd:pain.009.001.01']/[local-name()='MndtInitnReq' and namespace-uri()='urn:iso:std:iso:20022:tech:xsd:pain.009.001.01']/*[local-name()='GrpHdr' and namespace-uri()='urn:iso:std:iso:20022:tech:xsd:pain.009.001.01']"

Remove XML node in C#

My XML file looks like this:
<root>
<files>
<filesource uploadName="20180131T083441_638_Test.doc" originalName="Test.doc">c:\uploadDir\20180131T083441_638_Test.doc</filesource>
<filesource uploadName="20180131T083441_638_Test1.doc" originalName="Test1.doc">c:\uploadDir\20180131T083441_638_Test1.doc</filesource>
<filesource uploadName="20180131T083441_638_Test2.doc" originalName="Test2.doc">c:\uploadDir\20180131T083441_638_Test2.doc</filesource>
</files>
</root>
C# code:
// fileNodes has all 3 files sources
XmlNode filesNodes = xmlFile.findNode("/root/files");
List<string> filenames = new List<string>();
filesname.add("c:\uploadDir\20180131T083441_638_Test.doc");
filesname.add("c:\uploadDir\20180131T083441_638_Test1.doc");
Whatever variable filenames contains, I want to keep it in XML file and the rest I want to delete.
Used xml linq. Had to remove the folder name from the file name to get code to work
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
namespace ConsoleApplication23
{
class Program
{
const string FILENAME = #"c:\temp\test.xml";
static void Main(string[] args)
{
List<string> filenames = new List<string>();
filenames.Add(#"c:\uploadDir\20180131T083441_638_Test.doc");
filenames.Add(#"c:\uploadDir\20180131T083441_638_Test1.doc");
List<string> baseFilenames = filenames.Select(x => x.Substring(x.LastIndexOf("\\") + 1)).ToList();
XDocument doc = XDocument.Load(FILENAME);
List<XElement> filesources = doc.Descendants("filesource").ToList();
foreach (XElement filesource in filesources)
{
string uploadName = (string)filesource.Attribute("uploadName");
if (!baseFilenames.Contains(uploadName))
filesource.Remove();
}
}
}
}

Reading the XMl Response and Extracting the nodes using c#

I am trying to extract the XML Response from an API. My XML response looks like below. I tried different methods. can you please help me in reading and extracting the individual nodes from the XMl response.
For Example: I want to extract node from below XML response.
<string xmlns="http://schemas.microsoft.com/2003/10/Serialization/">
<RichDBDS><TrxDetailCard><TRX_HD_Key>5437845</TRX_HD_Key> <Invoice_ID>189809</Invoice_ID><Date_DT>3/24/2016 1:34:44 PM</Date_DT><Merchant_Key>2202</Merchant_Key><Reseller_Key>2</Reseller_Key><TUser_Name_VC>ITSTEST.ISMI</TUser_Name_VC><Processor_ID>CC Processor</Processor_ID><TRX_Settle_Key></TRX_Settle_Key><Tip_Amt_MN></Tip_Amt_MN><Approval_Code_CH>24032016013444</Approval_Code_CH><Auth_Amt_MN>184.99</Auth_Amt_MN><IP_VC>66.55.53.68</IP_VC><Account_Type_CH>MANUAL</Account_Type_CH><Last_Update_DT></Last_Update_DT><Orig_TRX_HD_Key></Orig_TRX_HD_Key><Settle_Date_DT></Settle_Date_DT><Settle_Flag_CH>FALSE</Settle_Flag_CH><Trans_Type_ID>Sale</Trans_Type_ID><Void_Flag_CH>FALSE</Void_Flag_CH><CustomerID></CustomerID><AVS_Resp_CH>Y</AVS_Resp_CH><CV_Resp_CH>M</CV_Resp_CH><Host_Ref_Num_CH>0b144718-3597-4cfb-a2b5-058679510f29</Host_Ref_Num_CH><Zip_CH>30328</Zip_CH><Acct_Num_CH>1111</Acct_Num_CH><Total_Amt_MN>184.99</Total_Amt_MN><Exp_CH>0917</Exp_CH><Name_on_Card_VC>Kenneth Boler</Name_on_Card_VC><Type_CH>VISA</Type_CH><Cash_Back_Amt_MN></Cash_Back_Amt_MN><Result_CH>0</Result_CH><Result_Txt_VC>approval</Result_Txt_VC><Trans_Status>Settled</Trans_Status><PO_Num></PO_Num></TrxDetailCard></RichDBDS>
Try code like below using XML Linq. I used Load(FILENAME or URL) method, but you can also use Parse(STRING).
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);
var results = doc.Descendants().Where(x => x.Name.LocalName == "TrxDetailCard").Select(y => new {
TRX_HD_Key = (int)y.Element(y.Name.Namespace + "TRX_HD_Key"),
Invoice_ID = (int)y.Element(y.Name.Namespace + "Invoice_ID"),
Date_DT = (DateTime)y.Element(y.Name.Namespace + "Date_DT"),
Merchant_Key = (int)y.Element(y.Name.Namespace + "Merchant_Key")
}).ToList();
}
}
}

How can I put that into 2 string lists in csharp
Load it as a text file into a string or StringBuilder.
prefix it with <xml> and end it with </xml>
then use XmlDocument to load your xml
XML can have only one root tag. You input has more than one root. So you have to wrap your XML in a root like code below
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Xml;
using System.Xml.Linq;
namespace ConsoleApplication1
{
class Program
{
const string FILENAME = #"c:\temp\test.txt";
static void Main(string[] args)
{
string input = File.ReadAllText(FILENAME);
input = string.Format("<Root>{0}</Root>", input);
XElement root = XElement.Parse(input);
}
}
}
