can I use Linq to Xml to alter an XSD?

Question

I've got a node in an XSD that I'd like to modify. I'd like to change the "name" value in this node:

<xs:element name="NewDataSet" msdata:IsDataSet="true" msdata:UseCurrentLocale="true">

However when I try to find that node via this code, I get either no nodes or an error, depending on what I try.

xsdDoc.Descendants("element").Where(x => x.Attribute("name").Value == "NewDataSet").Single().SetAttributeValue("name", "newValue");

Linq To Xsd isn't an option, since it looks like it's open source and that will mean all sorts of red tape (at work).

Is this possible, or am I out of luck?

Answer 1

You need an XNamespace for the "xs" namespace, then you need to use xsdDoc.Descendants(ns+"element").

---

XNamespace xs = "http://www.w3.org/2001/XMLSchema";
doc.Descendants(xs + "element").
    Where(x.Attribute("name") != null 
    &&  x => x.Attribute("name").Value == "NewDataSet").First().
    SetAttributeValue("name", "newValue");

Just a guess, but it could be a namespacing problem, try using LocalName, like in this question:
