Selecting XML Nodes Using XPath Syntax
Nov 9, 2011
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"?>

I have the following XML from Amazon's Marketplace API. I need to sum all the values of Item/ItemPrice/Component[type='Principal']/Amount for all Items to compute an order total. Is this possible to do using LINQ to XML in VB.NET?
<?xml version="1.0"?>
<AmazonEnvelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="amzn-envelope.xsd">

I am trying to identify duplicate serial numbers from the following xml using XPath 1.0 and then evaluating it in .Net using an XPathNavigator.
<?xml version="1.0" encoding="utf-16"?>
<Inventory xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Items>
[code]....
I tried to do this by evaluating this
//Items/Item/SerialNumber
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.

What is the proper syntax for this:
Dim qry As <??> = From f In dirInfo.GetFiles("*.QBW") Select File = f.FullName, Include = True
Dim dt As DataTable = qry.CopyToDataTable()
I tried as "IEnumerable(Of DataRow)" but that didn't work. At runtime it said:
Unable to cast object of type
'WhereSelectArrayIterator2[System.IO.FileInfo,VB$AnonymousType_02[System.String,System.Boolean]]'
to type
'System.Collections.Generic.IEnumerable`1[System.Data.DataRow]'.

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.
1) If parent is checked, check all child nodes.
2) If just one child node is unchecked, uncheck parent node.
That's it! I've been looking for this for 30 mins and I cant find it. Maybe because my vb.net is old, it doesnt seem to be the same as others =/ I'm using vb.net 2003.

I have a treeview that is populated from a HDD folder collection. Its structure is similar to the following (however the structure is dynamic):
My Disk:
|
|--folder1(tag:folder)
| |--subfolder1(tag:folder)
[code]....
I call the sub as follows:
deleteNode(treeview1.Nodes(0).Nodes)
However, the above is not working properly. It deletes only some nodes and not all the targeted nodes.

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.
I think the problem might be that the original program had the code within the class of a wpf window while it was moved to a abstract class where it doesnt work.[code...]

I have a XPath expression that is supposed to return/get only one node out of the XML document. But it is getting more than the one. I don't understand why.

Dim xmlNS As XmlNamespaceManager = New XmlNamespaceManager(xmlNameTbl)
xmlNS.AddNamespace("asp", "http://test.com/asp")

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.
<PLUS_BORROWER Type="Primary"> <SOCIAL_SECURITY_NBR>123459999</SOCIAL_SECURITY_NBR> <CREDIT_SCORE ModelName="Emperica">793</CREDIT_SCORE> <DAYTIME_PHONE_NBR>4077889999</DAYTIME_PHONE_NBR> <DAYTIME_PHONE_EXT>101</DAYTIME_PHONE_EXT></PLUS_BORROWER>
I have the following code that will pull off the first PLUS_BORROWER if the Type='Primary', but I am having trouble expanding it.
oExtraData.Load(myXMLFile) 'only select nod with type attribute equal primary Dim oNode As Xml.XmlNode = oExtraData.SelectSingleNode("//PLUS_BORROWER[@Type='Primary']") 'get credit score node Dim scoreNode As Xml.XmlNode = oNode.SelectSingleNode("CREDIT_SCORE") MsgBox("I have the Primary") MsgBox("Credit score is " & scoreNode.InnerText)

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. Best thing for me is if I am able to access the needed <div> using something like XPATH so I can target only those I need.
My Code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
