I need to update the element value in the above values. The old value is:
<SelectedPIN>0123</SelectedPIN>
And the new value should be:
<SelectedPIN EncryptedPIN="TKDS" FormNumber="000793906306">****</SelectedPIN>
Can anyone can help me on this?
If I selected the BCIRequest element, it's returning a null value. I've tried many solutions but unable to get one working on this XML file.

There many ways an Xml can be be modified, I prefer XDocument
XDocument doc = XDocument.Parse(input);
foreach (var element in doc.Descendants("SelectedPIN")) // filter if you want single element, in example I modifed for all elements.
{
element.Add(new XAttribute("EncryptedPIN", "TKDS"));
element.Add(new XAttribute("FormNumber", "000793906306"));
element.Value = "xxxxx"; //new value
}
and finally you can save the document using
doc.Save();
Take a look at this Demo

The root node (BCIRequest) contains a namespace so you need to include that into your query. Something like this should work:
XNamespace ns = "urn:xxxxxx:bci:request";
IEnumerable<XElement> collection = doc.Elements(ns + "BCIRequest").Elements(ns + "Card").Elements(ns + "SelectedPIN");

How to show specific information on xml

I have a c# console application where I update, add and delete information from an xml which works so far. But when i show the xml in my console with WriteLine it shows like this:
<ArrayOfKunde xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Kunde id="1">
<firstName>Hasan 2</firstName>
<lastName>sad</lastName>
<adress>sdfd</adress>
<birthday>vcxbgf</birthday>
<bankDetails>bcgh</bankDetails>
</Kunde>
<Kunde id="2">
<firstName>ghf</firstName>
<lastName>nbv</lastName>
<adress>bjk</adress>
<birthday>hjvn</birthday>
<bankDetails>jhgj</bankDetails>
</Kunde>
<Kunde id="3">
<firstName>mbn,</firstName>
<lastName>hgj</lastName>
<adress>ghj</adress>
<birthday>ghjg</birthday>
<bankDetails>hghj</bankDetails>
</Kunde>
</ArrayOfKunde>
it is probably due to my code to print it:
string filepath = "customerdatabase2.xml";
var xDoc = XDocument.Load(filepath);
Console.WriteLine(xDoc);
I wanted to ask if there is any way for me to filter what is shown? For example I do not want to show:
<ArrayOfKunde xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
Use: XDocument.Descendants
So your code can be:
string filepath = "customerdatabase2.xml";
var xDoc = XDocument.Load(filepath);
foreach (var node in xDoc.Descendants().Skip(1))
Console.WriteLine(node);
But this is very much tied to your Xml structure. Note that I am skipping 1st descendant because that will be the Top level ArrayOfKunde node.

C# search tag in XML and show another tag

I have the following XML-File.
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<Contacts>
<Contact>
<Name>Example</Name>
<PhoneNo>0481-12345678</PhoneNo>
<SalesPhoneNo>310<SalesPhoneNo />
</Contact>
</Contacts>
Would it be possible to search for the PhoneNo 0481-12345678 in the XML and then only show the SalesPhoneNo 310.
You could use an XPath query to do this. For example,
var xml = #"<Contacts>
<Contact>
<Name>Example</Name>
<PhoneNo>0481-12345678</PhoneNo>
<SalesPhoneNo>310</SalesPhoneNo>
</Contact>
</Contacts>";
XDocument xDoc = XDocument.Parse(xml);
// this will return 310
string phoneNo = '0481-12345678';
var salesPhoneNo = xDoc.XPathEvaluate("string(//Contact[PhoneNo='" + phoneNo + "']/SalesPhoneNo)");
Note you need to add a using System.Xml.XPath to use XPath query on an XDocument

Resolve multiple namespace

How would I get the XElement for the "HR" and "Cad" nodes in the following XML file:
<?xml version="1.0" encoding="UTF-8"?>
<gpx xmlns="http://www.topografix.com/GPX/1/1" xmlns:gpxtpx="http://www.garmin.com/xmlschemas/TrackPointExtension/v1" xmlns:gpxx="http://www.garmin.com/xmlschemas/GpxExtensions/v3" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" creator="StravaGPX" version="1.1" xsi:schemaLocation="http://www.topografix.com/GPX/1/1 http://www.topografix.com/GPX/1/1/gpx.xsd http://www.garmin.com/xmlschemas/GpxExtensions/v3 http://www.garmin.com/xmlschemas/GpxExtensionsv3.xsd http://www.garmin.com/xmlschemas/TrackPointExtension/v1 http://www.garmin.com/xmlschemas/TrackPointExtensionv1.xsd">
<metadata>
<time>2011-07-16T13:39:22Z</time>
</metadata>
<trk>
<name>07/16/2011 Toronto, ON, Canada</name>
<trkseg>
<trkpt lat="43.7076220" lon="-79.3164530">
<ele>138.4</ele>
<time>2011-07-16T13:39:22Z</time>
<extensions>
<gpxtpx:TrackPointExtension>
<gpxtpx:hr>124</gpxtpx:hr>
<gpxtpx:cad>90</gpxtpx:cad>
</gpxtpx:TrackPointExtension>
</extensions>
</trkpt>
</trkseg>
</trk>
</gpx>
I can resolve the element with the following code:
loaded.Descendants("{http://www.topografix.com/GPX/1/1}trkpt") // Where 'loaded' is the XDocument
but when I look at the element in the debugger it only shows me the <ele> and <time> elements and ignores the <TrackPointExtension> and <extension> elements that are descendants.
Thx in advance!
It isn't very clear how you used debugger to check, but as far as I can see there should be no descendant of selected node ignored by debugger.
To select an element from XML having multiple namespace prefixes, you just need to use right XNamespace prefix for right element, for example :
XNamespace ns = "http://www.topografix.com/GPX/1/1";
XNamespace gpx = "http://www.garmin.com/xmlschemas/TrackPointExtension/v1";
var trackPointExt = doc.Root
.Element(ns+"trk")
.Element(ns+"trkseg")
.Element(ns+"trkpt")
.Element(ns+"extensions")
.Element(gpx+"TrackPointExtension");
var hr = (int)trackPointExt.Element(gpx+"hr");
var cad = (int)trackPointExt.Element(gpx+"cad");
Console.WriteLine(hr);
Console.WriteLine(cad);

But when I am trying to parse using following code I am not able to get any descend or any node
XDocument xDoc = new XDocument();
xDoc = XDocument.Parse(data);
var xEle = xDoc.Root.Descendants("categories");
But xEle is not having any categories. Please let me know what is the issue??
Your XML has a default namespace - so the elements in it are in that namespace. The methods which find elements in LINQ to XML are namespace sensitive. You want:
XNamespace ns = "urn:types.partner.api.shopping.com";
XDocument xDoc = new XDocument();
xDoc = XDocument.Parse(data);
var xEle = xDoc.Root.Descendants(ns + "categories");

Add node and elements in xml using C#/Linq

I have an xml file like this,
<?xml version="1.0" encoding="utf-8" ?>
<root>
<FeaturedProductCategories>
<FeaturedProductCategory>
<FeaturedProducts>
<FeaturedProduct>
<ContentSelector datavalue_idtype="content:smartform" datavalue_displayvalue="«Smart Form:49»">49</ContentSelector>
</FeaturedProduct>
</FeaturedProducts>
</FeaturedProductCategory>
</FeaturedProductCategories>
</root>
I want to modify it like the one below,
<?xml version="1.0" encoding="utf-8" ?>
<root>
<Title>HomePage</Title>
<FeaturedProductCategories>
<FeaturedProductCategory>
<FeaturedProducts>
<FeaturedProduct>
<Products>
<Product>
<ProductTitle>Product</ProductTitle>
<ProductDate>03-08-2012 11:57:25</ProductDate>
<ProductImage>
<img src="ex1.jpg" />
</ProductImage>
<ProductThumbnailImage>
<img src="ex2.jpg" />
</ProductThumbnailImage>
<ProductCaption>Product Caption</ProductCaption>
<ProductImage>
<img src="ex3.jpg" />
</ProductImage>
<ProductThumbnailImage>
<img src="ex4.jpg" />
</ProductThumbnailImage>
<ProductCaption>Product Caption</ProductCaption>
</Product>
</Products>
</FeaturedProduct>
</FeaturedProducts>
</FeaturedProductCategory>
</FeaturedProductCategories>
</root>
All the new nodes and values are to be added through a C# function. Let us assume these new values as static values for now.
Also the node "FeaturedProduct" is not only one. There are a lot of nodes in that name. I want to modify all the "FeaturedProduct" nodes.
You should take a look at the XDocument class here:
http://msdn.microsoft.com/en-us/library/system.xml.linq.xdocument.aspx
I had to do something very similar to this a couple of weeks ago; XDocument is more willing to manipulate data, and using LINQ with it is incredibly easy.
This doesn't use linq exactly, but It will serve your purpose
XmlDocument xDoc = new XmlDocument();
xDoc.Load("filename.xml");
foreach (XmlNode xNode in xDoc.SelectNodes("//FeaturedProduct"))
{
XmlElement newElement = xDoc.CreateElement("newElementName");
XmlAttribute newAttribute = xDoc.CreateAttribute("AttributeName");
newAttribute.Value = "attributeValue";
newElement.Attributes.Append(newAttribute);
xNode.AppendChild(newElement);
xNode.InnerText = "myInnerText";
}
Also, This Documentation is a very handy reference for Xpath
Here's how to do it with Linq:
string documentXml = #"<?xml version=""1.0"" encoding=""utf-8"" ?>
<root>
<FeaturedProductCategories>
<FeaturedProductCategory>
<FeaturedProducts>
<FeaturedProduct>
<ContentSelector datavalue_idtype=""content:smartform"" datavalue_displayvalue=""«Smart Form:49»"">49</ContentSelector>
</FeaturedProduct>
</FeaturedProducts>
</FeaturedProductCategory>
</FeaturedProductCategories>
</root>";
string productsXml = #"<Products>
<Product>
<ProductTitle>Product</ProductTitle>
<ProductDate>03-08-2012 11:57:25</ProductDate>
<ProductImage>
<img src=""ex1.jpg"" />
</ProductImage>
<ProductThumbnailImage>
<img src=""ex2.jpg"" />
</ProductThumbnailImage>
<ProductCaption>Product Caption</ProductCaption>
<ProductImage>
<img src=""ex3.jpg"" />
</ProductImage>
<ProductThumbnailImage>
<img src=""ex4.jpg"" />
</ProductThumbnailImage>
<ProductCaption>Product Caption</ProductCaption>
</Product>
</Products>";
XDocument document = XDocument.Parse(documentXml);
var targetNodes = from featuredProduct in document.Descendants("FeaturedProduct")
from contentSelector in featuredProduct.Elements("ContentSelector")
select contentSelector;
foreach (var targetNode in targetNodes)
{
targetNode.ReplaceWith(XElement.Parse(productsXml));
}
Console.WriteLine(document.ToString());
