I have modified the MSDN example to reflect my problem. When using a namespace I can't get the document to validate as I would expect and when validating a document that doesnt have a namespace it validates regardless of whether or not it has an error in it or not.
Dim errors As Boolean = False
Private Sub XSDErrors(ByVal o As Object, ByVal e As ValidationEventArgs)
Console.WriteLine("{0}", e.Message)
errors = True
End Sub

I'm trying to figure out a way to validate the user data entered:

This is in MVC3, VB.net. I'm looking for an easy way to validate a users input data into the editorfor field.
I need to read an xml document from a database record into an XDocument object in order for it to be deserialized. So that the deserialization will work, I need to apply a specific namespace to each of the level 1 elements. So XML looks a bit like this:

How do I prevent the blank/empty namespace being added to each child element of the element to which the required namespace has been applied?
Imports System.Windows.Forms
ERROR : 'Namespace' can occur only at file or namespace level
The type or namespace name 'Messaging' does not exist in the namespace 'System' (are you missing an assembly reference?)
View 2 RepliesThis class is located in the namespace Acme.Infrastructure.Interface.A class with the same name EventArgs exists in the System namespace.In another project in my solution I have a class Acme.BusinessModules.MyModule.MyClass.When attempting to use the EventArgs class I have to fully qualify the class name or the compiler thinks I am using the System.EventArgs class.My understanding of namespace resolution was that the compiler would first look for the class in the current namespace, and then its parents. It seems that the compiler checks in System before it checks in sibling namespaces. Is it correct that System is checked before the sibling? Or is this behaviour caused by other issues (Imports order?)?
View 1 RepliesI've just got to know XDocument in VB .NET and really like the way I can write XML documents in my code but have just one little problem I can't find a good solution for. The problem is with IIF that I use to check some conditions for example if a node should be printed or not.The problem is when I want to print multiple nodes (from a list of strings) if my conditions are true first. Here is the problem code where I'm checking few conditions and in true part I'll try to loop nodes:

I am up to the point where my application requests and receives a response from digg.com, but I cannot figure out how to properly dimension the XDocument class (as the tutorial shows) to read the xmlcontent that is retrieved.the tutorial is in C# (which I know very little about), but I do not see why I cannot access this class. Intellisense suggested replacing XDocument with Document.Run, but that got me nowhere. I also read that this class was part of the System.Xml.Linq namespace, but even trying to dimension my variable as
Dim xS as System.Xml.Linq.XDocument
gives me nothing.
I cannot get anything back from the following code... it always pops 0, and the _Qry is never populated, even though _MBXml is populated properly (hovering during debug shows it)
_MetaBasePath += "IIS6-MetaBase.xml" '"metabase.xml"
_MBXml = XDocument.Load(_MetaBasePath, LoadOptions.PreserveWhitespace)
_Qry = (From n In _MBXml.<IIsWebServer>

I am using XDocument to parse an XML file. The first thing I'm trying to do is count the number of <entry> elements under the root. I have this code:
dim xmldoc as Xdocument = Xdocument.parse(string variable)
Messagebox.show(xmldoc.root.<entry>.Count)
I will paste the string containig the XML below (it's kinda long, but not too much). Everytime I run this script, it says there are 0 <entry> child elements, but that's clearly not the case. I'm not sure what I'm doing wrong here.. not sure if it has something to do with namespaces or what.

I'm loading an xml document like this:
Dim doc As XDocument = XDocument.Load(FilePath)
I am then able to read the contents. However I need to get the namespace of the xml document. I can easily copy and paste it from the xml file and then import the namespace, but I'm building an importer class and I need to get the namespace so I can make my class as dynamic as possible.
I am stuck on a project which needs to exchange data between two programs who have different coontrol files. Program A just creates a a XML File whereas Program B needs the input as an array with two "columns" - but how do can I do the conversion?

` <Presentation>
<Options Name="1">

But how can I achieve this? I am using vb.net and LINQ and have no idea how to solve this problem. I tried some LINQ queries but I get only indivudal nodes or attributes so I think it would be better to try a different idea.

and the issue I appear to be having is in the function "Unable to cast object of type'WhereSelectEnumerableIterator`2[System.Xml.Linq.XElement,System.String]' to type 'System.IConvertible'."What I am trying to do is populate a strongly typed list of the records, where the list should contain the record id, the field value, and the fields name
The XML String I am getting from other application is converting & to & and 0F to ?F etc. I am loading the XML string into XDocument and inserting into db using linq. Is there any easy way to replace those characters with actual ones.
