expression in a custom XSLT Context Function (implementing IXsltContextFunction like this MSDN example) in .Net but the Invoke function gets called one result at a time so I have no visibility of the other results to find duplicates.
1) Is there a way of doing this using a single XPath 1.0 expression?
2) Is there a way of passing in an array of elements into a single Invoke call of the custom XSLT Context Function class? I'm working in VB.Net but am happy with any C# examples anyone can share.

Given the xml below why does the first selectsinglenode call not work but the second one does? Are the single quotes specifying a string type or something? Dim dbglvlnode As Xml.XmlNode = doc.SelectSingleNode(String.Format("Config/Scanner[DeviceID = '{0}']/DebugLevel", XMLstuff.DeviceID)) Dim dbglvlnode As Xml.XmlNode = doc.SelectSingleNode(String.Format("Config/Scanner[DeviceID = {0}]/DebugLevel", XMLstuff.DeviceID)) <?xml version="1.0" standalone="yes"?> [Code] ......

My goal is to just select the 2nd one, the <span> tag and am not sure why <p> tag is also being selected. If it selects <p>, but why wouldn't it also select the <strong> or <a>, and why not the <table> or <td> that contain the <p>?

I use an XPathNavigator Select to get a node iterator in the code below and get an invalid token error. If I take out the @contract I do not get an error. I then have to use MoveToAttribute, which works, but shouldn't be needed. Why do I get an error when the @ syntax is valid XPath?
I'm all new to this treeview business. I have a fixed treeview, very simple and basic. Only two levels, parent and child nodes. I just need two things out of this treeview.

I have an XElement and an XPath expression that selects a node from it. It works fine in the original program that I wrote it in but doesnt work if I paste it to another program. I've checked the references and import statements.

There are multiple occurances of the PLUS_BORROWER data. For each occurence of PLUS_BORROWER, I want to save the CREDIT_SCORE and DAYTIME_PHONE_NBR when the Type= And SOCIAL_SECURITY_NBR are certain values. Then I want to execute a loop and extract the Credit_Score and Daytime_Phone_Nbrs.

I'm trying to get the value of a specific <div> from an html. This div has a class attribute of "itemPrice6", but problem is that this class appears few more times for other <div>s in which i'm not interested in.
