I have already read several existing posts about xsd:extension, but do not
find something useful to my test case. I have one xml file and one xsd file.
I can use a simple command line (C#) program to validate the xml file against
the xsd file without any error. The problem is ...

Below is the schema snippet I am trying to explore attributegroups and attribute's use property. However I am getting a validation error saying "undefined value for base encountered", pointing to <xs:restriction>. Please help.
<?xml version="1.0" encoding="UTF-8"?>

I'm trying to mirror some classes in an XML Schema:
   abstract class EndPoint
   class FileEndPoint: EndPoint
   class FtpEndPoint: EndPoint

I'm serializing a class instance to xml file, but keep getting default
namespace decleration, even I don't declare these namespace in my class:
<cXML xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" otherAttri.. />

I'm having a problem attaching a name space.  I'm getting an xml

I would like to select some nodes from a very large XML document and then

Is it possible to filter an XML document twice?   I have filter 1, and later
in the code I want to apply filter 2. Filter 2 should be based on the
results from filter 1.  I have tried using an XPathNavigator:
XPathDocument xpDocument = new XPathDocument(MyXMLFile);

Trying to find out a way how to restrict value of the element by name of an

I have a string containing valid XML.
How do I populate a dataset based on the string, without reference to an XML
schema or writing the XML to file and reading it back in again?

This is my first time trying to take the results of a query that

So my question is "Is it possible to group (Muenchian method)
over multiple nodes?" I will use an example to try to explain what

Anyone care to recommend a web site that has some really good examples of
XPath queries utilizing attributes?
