I'm trying to use LINQ to XML to create an Excel spreadsheet. I created a template spreadsheet, exported it to XML, pasted the XML into my code and then began to edit it. When I try to create a set of XElements using LINQ, I get these errors:
The first squiggle under <Cell> says "attribute specifier is not a complete statement"
The second under ss says "'>' expected"
The third under Type says "'Type' is a type and cannot be used in an expression"
Ignore the error under "Lot 1..." I will be putting an expression hole there.
The squiggle under </Cell> says "Identifier expected".

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 used reader.name is giving me RUNWAY which is correct as the elements name. I tried getAttribute and it give me all of the values of the attributes, but not there name.

A former co-worker wrote a class in C# that was to be used as an attribute. I'm having to convert his work to VB (yeah, it's pointless and way more work than necessary, but management thinks it's a good idea). Unfortunately I'm having an issue because one of the main properties of the class is an ArrayList which is set with a ParamArray in the constructor. The class looks like this (note I've tried to abstract out the problem, so this is a simplified version of the class only)
<AttributeUsage(AttributeTargets.Field Or AttributeTargets.[Property])> _
Public Class LabelAttribute
Inherits Attribute
Public Sub New()
[CODE]........
In the first one, there is just the single label being added. No Problem. In the second one there are 2 different labels being added. Again, no problem. The third one, however, is a problem because it's assuming that the "Description", which is supposed to be the description is instead being interpreted as another label.
This wasn't a problem in C# because it could be set as follows:
[CODE].................
Of course this doesn't work in VB because optional parameters aren't referred to by name as they are in C#. As a stopgap I've changed the constructor to allow only a single label like this
CODE]..................
But that undermines some of what this class is meant to do. Does anyone know how, or even if I can get the same basic functionality to work in VB?
Think there must be a way to make the existing design work. Imagine this class was built into a library that I could not modify. Would I be forever forbidden from setting Description because of this design?

[code]...Add an attribute to a root node?
View 3 Replies
Jan 20, 2009
I'm using VB 2008 and I'm trying to add a xmlns="mynamespace" attribute to an XDocument's root element.The XML document is created by a 3rd party, and I have loaded it into a VB XDocument object. As it comes, it has no namespaces. I have been working on a local copy and I added in a namespace in a text editor, so that I can use the XMLToSchema in VB to enable intellisense etc, as per the instructions in the Beth Massi vids at MSDN. Now the rest of the code works I want to open the live documents again. Without the namespace, my XML literals don't resolve.I've tried unsuccessfully to add in the XMLNS property to the root tag using a few methods, and the nearest I got was the following three code samples.
Dim myNS As XNamespace = "urn:nbf:namespacename"
myXML.Element("nameofrootelement").Add(myNS)
^^^^ The namespace was added as the value of the root element, not as an attribute.
XML.Root.Add(New XAttribute("xmlns", "name"))
^^^^ Generated the error: Run-time exception thrown : System.Xml.XmlException - The prefix '' cannot be redefined from '' to 'name' within the same start element tag.
but
XML.Root.Add(New XAttribute("test", "name"))
^^^^ works correctly. Presumably it doesn't like me manually trying to set a reserved attribute? This namespacing seems way too over complex from some of the Googling I've done.I thought to .ToString it, then modify, then .Parse it also, but I wanted a better solution so that it would help me understand it a little better! I did try this though, and as you rightly point out, it affects all the descendants too, so thus it still breaks.
I will be working with multiple XML feeds all produced by different third parties, and I think for simplicity I will be leaving out the namespacing entirely!My own custom parsing function rewrites the third party feeds into one uniformed document, which then gets processed by another routine. I'll be able to add a ns to that intermediate piece of XML which will help when coding the secondary function.
