XML node Challenge 3

You have a good start. Just run a logic check inside the foreach statement. Check to see if an element <AddressTypeCode> exists as a child of the XElement "address" and if so, what its value is. You can then act accordingly.

Hi teknovation;

See if this will meet your needs.

// Load Document
XDocument xdoc = XDocument.Load("Path and file name of the XML doc");
// Get a ref to the XML Namespace
XNamespace ns = xdoc.Root.Name.Namespace;

// Get the Ship to Address  
var addresses = xdoc.Root.Descendants(ns + "Address").ToList();

// If you want the Ship To address it will be element 0 and the Bill To address is element 1
// XDocuments are process in document order 
int idx = 0;  // 0 = ST and 1 = BT
// Get the proper address
XElement addInfo = addresses[idx];
Console.WriteLine("{0} {1}, {2}, {3}, {4}, {5}, {6}, {7}, {8} ",
    (idx == 0) ? "The ship to address is:" : " The bill to address is:",
    addInfo.Element(ns + "AddressName").Value, 
    addInfo.Element(ns + "AddressAlternateName").Value,
    addInfo.Element(ns + "Address1").Value,
    addInfo.Element(ns + "Address2").Value,
    addInfo.Element(ns + "City").Value,
    addInfo.Element(ns + "State").Value,
    addInfo.Element(ns + "PostalCode").Value,
    addInfo.Element(ns + "Country").Value
    );

@Fernando - Your code assumes that the ship to address will come first. There is absolutely no guarantee of that in the XML. You will need to look at the actual element value to correctly determine if it's a bill to or ship to address.

@Russ - The question states, "the only difference is the first Address tag is meant for SHIP to address which is showned in the <AddressTypeCode> with value of "ST" and BILL TO address shown with "BT" value", I have taken that to mean that the first of the two nodes is Ship to.

In this case yes but you can't guarantee the input. The safer approach would be to check the item value. The XML would still be 100% valid if the two address elements appeared in the reverse order but the output would be wrong. Coding to assumptions is never a good idea.

Something like below.

This is great Karrtik - but is there a way to just pull out 1 field at a time in this format?

I just quickly mock this up for the purpose of example, so the data isnt exactly matching the file output. But just to give you an idea on what I need.

The ship to address is: Main Headquarters
The Location Code Qualifier is: 51
The AddressAlternateName is: ABC 123  
The Address Name is Safeway 7th Street

What about contact details in Bill to address, do you want that to be also printed, and if it would help given an XML (since you said the first one in the question is just a mock up) what would be the expected output? In that contact details there is a contact code type as well as "BD". So before I suggest a modified version of my solution, wanted to what is  your exact output requirement given an XML?

<Contact>
					<ContactTypeCode>BD</ContactTypeCode>
					<ContactName>Jane Doe</ContactName>
					<PrimaryPhone>111-222-3333</PrimaryPhone>
					<PrimaryFax>111-222-3333</PrimaryFax>
					<PrimaryEmail>buyer@TEST.com</PrimaryEmail>
				</Contact>

Yes sorry both - i want to be able to access specific xml tags in both addresses

Something like below, which produces the below shown output, the previous code to join all the elements to one string is also present, so if you do not want it you can remove that.

wow this works - but far more advance that I wanted.

How can I just say pull one node from the Address child xml nodes?

Instead of doing a for each, I need to just grab say the "Contact Name" or "primary phone" value?

Something like below.

            var btaddreselements = (from saddress in xdoc.Descendants(ns + "Address")
                                 where saddress.Element(ns + "AddressTypeCode").Value == "BT"
                                 select saddress).FirstOrDefault();
            //Address Name
            var addressname = btaddreselements.Descendants(ns + "AddressName").FirstOrDefault();
            Console.WriteLine(addressname.Name.LocalName + " : " + addressname.Value);
            //Contact Name
            var contactName = btaddreselements.Descendants(ns + "ContactName").FirstOrDefault();
            Console.WriteLine(contactName.Name.LocalName + " : " + contactName.Value);
            //PrimaryPhone
            var primaryphone = btaddreselements.Descendants(ns + "PrimaryPhone").FirstOrDefault();
            Console.WriteLine(primaryphone.Name.LocalName + " : " + primaryphone.Value);

hmm the address name is null.    

   var staddelements = (from saddress in xdoc.Descendants(ns + "Address")
                                             where saddress.Element(ns + "AddressTypeCode").Value == "ST"
                                             select saddress.Descendants()).FirstOrDefault();

Can you share your XML that you used, because the XML that you gave me had a node called AddressName?

its the same xml, there is an addressname

I have posted the XML that I used, and using that the above code, here is the output I get for AddressName. Please check your namespace ns and see what it is set to, based on my XML I have set it to "www.test-inc.com".
 

This strange:

         var staddelements = (from saddress in xdoc.Descendants(ns + "Address")
                                             where saddress.Element(ns + "AddressTypeCode").Value == "ST"
                                             select saddress.Descendants()).FirstOrDefault();  
                       
                       
                        var btaddelements = (from saddress in xdoc.Descendants(ns + "Address")
                                             where saddress.Element(ns + "AddressTypeCode").Value == "BT"
                                             select saddress.Descendants()).FirstOrDefault();
                           

                            foreach (var line in btaddelements)
                            {
                                Console.WriteLine(line.Name.LocalName + " : " + line.Value);
                            }
                             var addressname = btaddelements.Descendants(ns + "Address1").FirstOrDefault();
Console.WriteLine(addressname.Name.LocalName + " : " + addressname.Value); ;


This whole line of code produces what I want except the very last line where it's bolded the var addressname is NULL. It produces the line by line item as shown for the foreach statement.

thanks so much it worked!
