How do I work out what the namespace declaration is for the Extension node?I want to return all of the child nodes under: GPO->User->ExtensionData->Extension..[code]I get the following error: Sequence contains no elements..Also, the XML sample I have provided is only a small snippet, the ExtensionData->Extension nodes can be nested in different areas, so I was hoping to find the way of specifying the full path.

I am using VS 2008 but am having problems getting the namespace system.xml.linq to be recognized. I am attempting to add the reference but I don't seem to be be allow to select it.System.XML.Linq is grayed out in the AddReference menu. What must I do to add this reference to my project?
View 3 RepliesI'm trying to grasp the linq to xml 'inline query syntax' features of VB.Net First I tried with this simple xml file:
<?xml version="1.0" encoding="utf-8" ?>
<Root>
<Child Name="somename">
[code]....
This xml, when loaded in an XDocument, can be loaded and queried as follows:
Dim xdoc = XDocument.Load("sample.xml")
Console.WriteLine(xml.Root.<Child>.@Name)
Then I change the <Root> element in the sample xml file to:
<Root xmlns="http://SomeNamespace">
Now I can't seem to use the convenient 'Axis Properties' syntax anymore... I can only get it to work with the explicit XElement syntax:
Dim ns As XNamespace = "http://SomeNamespace"
' works, but I would like to use the same syntax as above...
Console.WriteLine(xdoc.Descendants(ns + "Child").First().Attribute("Name").Value)
I have 290 Group Policy Backup xml files which I need to enumerate in separate folders.
With each Group Policy backup xml file, I need to query the Policy settings.
Anyone who's looked at a Group Policy xml backup file before would know they're chock-a-block full of Namespace declarations.
I want to know, using Linq to XML, as I query each xml file, how can I dynamically query the XML the Namespace and then append the Namespace into the Linq query for the child nodes/values?[code]...

I was writing a generic class to read RSS feed from various source and to consolidate in one collection of object in VB.net.
Basically the function - using LINQ to XML - is working properly, but I have a problem when the RSS feed I am trying to read does not contain one of the node (as you know, many of them are optional). I would the returned value to be an empty string or nothing, but instead I get a runtime error back. I searched the web for the same problem and I found this post [URL] that apparently explain a workaround, but it does not work with my code.
I am also surprised by the little resources I am finding about this issue, so I am now wondering if I am even putting the question in the right terms...

I am using XElement to manipulate my xml file: to find target node and then add child node to it. But now I have one problem. Let's say my xml file looks like this:
<Report xmlns="MY_NAMESPACE"
<Width>100</Width>
<Height>100</Height>
[Code].....
The second <ReportItem> is the newly-added one, but sadly this is not a valid file (my parser is complaining in the further processing of xml file). So how can I make this new item look exactly like the existing one, without any namespace? This has been driving me crazy. I spent a whole day to figure out that I need to add the curly brackets so that it will find the target node (it doesn't work like what the link above says that it adds and searches the default NS automatically), but now it adds something unnecessary?

After being quite sick of the my.settings-file behavior, I started to create an XML-file (with unique values). Now this works great!!!

If a node belongs to a namespace, it's children by default belong to the same namespace. So there's no need to provide an xmlns attribute on each child, which is good. However. If I create two nodes like this:

I have built a database structure that represents a category tree to help classify some of the data we have stored. The implementation is that each record in the Category table has a nullable foreign key back into the Category table to represent the parent Category of this category (one-to-many), essentially allowing for subcategories within a broader parent level. There is a CategoryMembership table that links a record in the Item table to its respective Category (many-to-many). I have created the DBML for this database, and it has a member access structure that includes the following:

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?)?
