This is a spin off of my other thread: Write XML using XmlDocument
Now I have it creating an xml file and everything's good, I'm working on the the reading of it now. Here's my current
Try
Dim XmlDoc As New XmlDocument
XmlDoc.Load(m_ImportOpenFile.FileName)
[Code]....
Consider the following XmlDocument with namespaces:
<Report xmlns="http://schemas.microsoft.com/sqlserver/reporting/2005/01/reportdefinition" xmlns:rd="http://schemas.microsoft.com/SQLServer/reporting/reportdesigner">
<DataSources>

I am currently facing an issue when i get response from webservice, after reading response in response stream i want to load this response stream using xmltextreader. but when Load(xmlTextreaderObj) is called, it raises an exception displaying that "Root Element is Missing". Here is code which am using.
Dim wResp As HttpWebResponse = CType(wReq.GetResponse(), HttpWebResponse)
Dim respStream As StreamReader = New StreamReader(wResp.GetResponseStream())
Dim Resp As String = respStream.ReadToEnd()[code]....
Do you have a sweet solution in VB (visual studio 2008) to read an OWL file and display nodes on a treeview? It works great for XML but not for OWL when nodes are like as follow: [Code]
View 2 RepliesI am currently trying to load an XML file into my app. However, it keeps throwing an exception error (InvalidOperationException - Object reference not set to an instance of an object) and I can't work out why. have a look at the code below and see if you can spot the error? I'm still very much a beginner so i'm sure it will be something simple..
Public Class FrmXMLReaderTest
Inherits Form
Friend WithEvents txtOutput As TextBox

I know how to read user input using textbox but it only can read character and numbers. Is it possible that I want to read user input equation?
Example:
User type A+B
User put range of A and B.
1.25<A< 3.56
2.45<B< 9.87
I failed to read the equation using textbox. Is it there are other ways that can use to read equation input A+B?I am using VS2005 and VB.Net. I really new in this programming using VB.Net.
way to do the following in VB 2005:
I need to access, but not display, a web page out of a VB 2005 program. The web page would be an aspx page with a query string as part of the url - with the url using values acquired thru the program - e.g. www.mysite.com?arg1=this&arg2=that
So the aspx page would produce an html output with values I need placed in specific elements. I want to read that page from my app and do stuff with the resulting values.
I've reached a point where it's time to learn how to Read/Write XML files properly and I'm really confused to how we're supposed to do this. I've been reading up on using the XmlDocument, but all I'm finding is how to use it to read xml files. Right now I need to Write them, later I'll code the reading of them.
The data for the XML file comes from a couple of tables in a database too, I've got a Master/Child table (actually there's 5 child tables). I've got the data coming into DataTables and I've got the loops set up already, I'm just stuck to how do I take the Master table's row and store that data as an XmlNode then loop each of the 5 child DataTable's and add each row as a child node to the master's node.
and other non-visible characters such as whitespace in XmlDocument?I tried PreserveWhiteSpace = False and IgnoreWhiteSpace = True for XmlReaderSettings, but those didn't work.

and I need to pick node from Id 25 to id 75. It is a portion of XML. Original XML is very long. How to do it without XPath?

I am ably to load a XML file (via a filepath) to a datatable. See code below.However, I'd like to be able to load a in-memory XML document to a datatable.
Code: Public Function XmlToDataTable(ByRef filePath As String) As DataTable
Dim ds As New DataSet Dim dt As New DataTable ds.ReadXml(filePath) dt = ds.Tables(0).Copy()
Return dt
End Function
I have two XmlDocuments that both have a namespace attribute specified. Both documents have the same structure, but contain different data. I can't seem to get a specific node tree from one document added to the end of the same node tree in a second document. Here is an example of my two documents:
Document #1:
<?xml version="1.0"?>
<rootnode xmlns="http://www.mynamespace.com/Service/2012-06-18">
[code]....
I certainly know this is wrong... I've tried serveral different approaches. This particular approach adds all <Item> nodes to the destination document, but it adds them to the very bottom of the document instead of after the last <Item>. how to add a specific node tree an XmlDocument to a specific position in another document? Again, there is a namespace involved and the <Item> nodes have nested nodes/elements under each one.
NOTE: The <Id> nodes have example data to show uniqueness only. I can never count on any kind of numbering. The order of each <Item> node is totally unimportant. I'm just assuming it will be easiest to add additional <Item> nodes after the last one in the destination document.
I am having some problems building a properly formatted SOAP message using XMLDocument in VB.NET(C# answers are fine though). I am using the following code to manually create my SOAP message, what is happening is that the namespace prefix of the soap:Header and soap:Body are being stripped in the output XML:

trying to parse this:
<?xml version="1.0" encoding="UTF-8"?>
<directoryresponse xmlns="https://www.sisow.nl/Sisow/REST" version="1.0.0">

Here's my code:
XPath = "//directoryresponse/directory/issuer/issuerid"
Dim nodeList As XmlNodeList = XML.SelectNodes(XPath)
but nodelist.count=0...why?
I'm having trouble reading a simple xml file with the XmlDocument class. Here is my xml file:

I want the title attribute of the node but it gives me a message box instead saying: "System.Xml.XmlAttribute" How can I convert that or in some other way get the title attribute of the books? Another problem I will be running into is storing the books and readers in a 2D array dynamic array. How can I run through the <readers> nodes to store them in an array within the nodeTitle For Each loop?
I have published xml document through web service like this
<WebMethod()> _
Public Function HelloWorld() As XmlDocument
Dim xmlDoc As New XmlDocument

Whenever I try and get the InnerText of an element using an XmlDocument, it throws a NullReferenceException. Here is the code below:
Dim SetDoc As New XmlDocument
Dim xmlString As String = "<upload><links><bananas>apple</bananas><original>thirteen</original></links></upload>"
[Code].....
The same happens when I load exactly the same XML from file.
Visual Studio 2008. .NET 3.5 VB 2008 or VB9 as it is also called. I have an XML file that I need to parse efficiently. I had completed the project by means of pulling the document into an array and pulling the variables I needed via looping through the array. This turned out to be very inefficient as the file is quite large.
I am now looking into using XmlDocument or Linq to XML so that I can pull the variables that I need without looping. I read that Linq is the fastest so I was trying to go that route.
I have searched all over the place for examples of parsing xml documents and I can't find exactly what I need.
My XML file is formatted somewhat like this:
Code:
<Folder>
<set>
[CODE]............
The idea is that I need to get those <fp> values for certain f_types only. Not only that, but it also needs to <set> specific. You will notice that the second "<set>" has a <num> Value of 2 within the <data> tags.
So... I need to find a way to search for say all the <fp>'s in set one that are of f_type 5 only, exlcuding all of set 2's f_type 5. This XML is not ideal but re-formatting the XML is not an option for me. I have to work with what I got.
After hours of googling all I was able to do was pull all the Element values for each <F> child nodes if they included a f_type value of 5. But... It does it for the whole doc, not just the 1st set like I need.
I will post what I have so far: It is not much but I can't find great info on using Linq to xml that does what I am trying to do.

This doesn't even need to be enclosed in an XML block but for some reason it wouldn't work unless I put it into XML block.
Why does System.Xml.XmlDocument.LoadXml method throw System.Net.WebException ?if MSDN was right, LoadXml should at most give me a System.Xml.XmlException.Yet I have weird exceptions like:The underlying connection was closed: The connection was closed unexpectedly.
Dim document As New XmlDocument
document.LoadXml("<!DOCTYPE html PUBLIC ""-//W3C//DTD XHTML 1.0 Transitional//EN"" ""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd""><x></x>")
MsgBox(document.LastChild.Name)
I have an asp.net vb project that needs to parse some raw XML that is coming out of a database the XML is laid out like this:
[Code]....
I know that the error is because the attributes are not quoted. Is there anyway to make XmlDocument understand the attributes anyway or an easy way to use a reg expression to add quotes to the attributes before loading the string into the xmldoc?
I have working code to read an RSS feed that uses:
Dim doc As New XmlDocument
doc.Load("http://...")
Dim channel As XmlElement = doc("rss")("channel")
Dim items As XmlNodeList = channel.GetElementsByTagName("item")
Unfortunately the doc.Load call causes the rest of the program to become unresponsive until it finishes.What's the best way to perform the load asynchronously and have a callback function to process the data?Edit: Here's the code I've tried using WebClient - the Load method is still lagging:
Private Sub checkResults()
'request rss feed
Dim w As New System.Net.WebClient
[code]....
The rssReadCallback method is executed fairly quickly after calling checkResults, but then the UI freezes during the Load method.
I need to get a list of the item id attribute in a soap packaged XML file, in the example below ref-2 ref-3, but I'm having a problem finding examples that work and not even sure where my attempt at a linq to xml statement is failing. Are there any good examples of parsing a XMLDocument in a SOAP envelope or am I just making this way harder than it needs to be.

Is there more elegant syntax for reading/parsing Size and Point objects in an Xml document?
Source Xml Nodes:
<objSize>{Width=64, Height=64}</objSize>
<Location_X>20</Location_X>
<Location_Y>20</Location_Y>
[Code].....
I have control over both the source nodes and the parsing code... So I am just being too lazy with my XmlNode creation? Regardless is there any benefit to using XmlConvert v.s. using integer.parse (or .tryparse)?
This is a sample code in vb.net in which i retrieve the details of elements without attributes.
For Each standardItemInfoNode In ItemInfoNodes
baseDataNodes = ItemInfoNodes.ChildNodes
bFirstInRow = True
For Each baseDataNode As XmlNode In baseDataNodes
[code]....
How can i retrieve the details of the xml like having node with attributes and its child also having attributes. I need to retrieve all the attributes of node and its child node which are present in the middle of other xml tags.
I have an XMl string in a Field of a mySQL Table. I load an XMLdocument (xmlDoc) from that string
I then Search for a node and change an attribute. All good in here.Then I want to save changes that i made to the XMLDocument in string format so i can update my table in the DB.
How can I do this.?
If I execute xmldoc.save(), well, it will save a XML file. How can I save the changes that I have made but instead of savig the file, save it as a string so I can save it in my table.I really do not want to parse the XML string as a normal string to search my parameters and save it.
I am working on vb.net, but if you have code in other .net lang, no problem.The DB is in MySQL
I've got an XMLTextWriter writing to a Stream of a WebRequest. Everything works as it should:

How can I intercept this XML that's being written as an XMLDocument type? I tried snagging it from the stream but that gave me a 'The stream does not support reading.' exception
