I am using the .NET framework v2.0.40607 with Visual C# Express and I would
like to create some custom XPath functions to use directly in a XSLT
stylesheet.
I called System.Xml.Query.XmlArgumentList.AddExtensionObject(string, object)

How come the following XPath expression doesn't return any nodes?
descendant::*[node()=SignerInfo]
Here's how it's called on the document root node:
XmlNodeList list = m_xmlDoc.DocumentElement.SelectNodes(sXPathExpression);

I keep getting an error when I have a tick mark in a text value that I am
searching for in my XPath Query.
Example:
<Authors>

I have a root node attribute which contains a name space declaration.  I'd
like to put a reference onto the front of it (ie:  ns1:RootNode) where ns1 is
defined as the namespace I'm using.  Is there a way to do this in C#?
Also can I include other namespaces in this declaration as ...

This is my sample (simplified):
public class Binom
{
    [XmlAttribute("range")]

I developed a schema that uses the following for schema settings:
elementFormDefault="qualified"
xmlns:at=http://www.mycompany.com
targetNamespace="http://www.mycompany.com"

I have an xml file that is 63mb in size.  If I were to load this file
into memory, will it consume 63mb of memory or will it consume more than
that?
Thanks,

I am planning to test WSDL fine for a web service as follows:
1. Get a WSDL file from the web service.
2. Validate the WSDL file against the XML schema.
The problem I am facing is with the schema file.  I reffered to

I am doing a

I do this. code would help.

I am working on a project that will have about 500,000 records in an XML
document.  This document will need to be queried with XPath, and records
will need to be updated. I was thinking about splitting up the XML into
several XML documents (perhaps 50,000 per document) to be more ...

I have an XML file like this:
<?xml version="1.0" encoding="utf-8"?>
<SomeObject xmlns="http://www.abcinc.com/objectdefinition"
xmlns:someobj=http://www.abcinc.com/objectdefinition>

I'm trying to get the absolute xpath to a node in DOM (XmlDocument).  I know
I can build it by warlking the tree recursively, but I'm wondering if there
is an API in DOM or in XPathNavigator that allows me to get the absolute
path for a given node?

I have the following xml file (given to me not created by me)

I would like to know whether VS.NET can edit XML document and
intellisense information from the schema the XML document is based upon
?
If not then are there any other editors or VS plugins that can do the
