Linq To XML - Parsing XmlDocument Within A Soap Evevelope?
Apr 27, 2012
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.

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:

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)?

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.
[Code]:.....................
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.

I wrote a soap service in PHP using nusoap. It works fine with the test client I wrote in PHP, however, our customer wrote his client in vb.net and it is not working. There are no errors that I see, but the service is not parsing his requests properly.
I am letting nusoap generate the WSDL, and it looks fine. If I compare a message that I send in to one of his messages, I do see a few differences in the envelope, but I'm not sure if the problem is on my end or his.

I would like to parse through and display and picture and description for each 'item' in an XML file. I can't figure out the image part, and I've only been able to concatenate the 'description' to display it:

I'm at the right elements in the tree; I can display the first picture, and I've been able to access all of the 'description' elements. But I need to have each 'item' element display together.

I have one large XML file from one of our vendor and I am trying to pars it using Linq but it looks some wrong logic I am using.
This is xml file:
HTML
<Psw xmlns="http://localhost">
<exid>20</exid>
<Mes><Me>
<doc><ps>
<ghder> .....
The code I am trying:
Dim doc As XDocument
doc = XDocument.Load(TextBox1.Text)
Dim qList = (From xe In doc.Descendants.Elements("ghder") _
Select New With { _
.mid = xe.Element("MId").Value, _
.cdate = xe.Element("cD").Value _
' As well I need to get the value for pn child attribute }).FirstOrDefault
MsgBox(qList.mid)
Error for DBNull ' Object reference not set to an instance of an object.

I'm creating a vb.net winforms application that will take in user given strings, parse them, and print out labels with variable information. The given string will be used in all the labels, but the variable part of the string will change with each label.
My question is: is it better to parse the strings one time, then store those values in arrays, or to parse the string each time a label is printed? Which will perform better? Which is better practice? What is the proper way to test something like this?

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.

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 need to use a web service that was provided to me and that uses SOAP with attachments as a means of communication. It also uses WS-Security 1.0 as a form of authencation (user and pass in plain text).I will be working on VB.NET and my experience with web services is very slim, and goes as far as creating a WCF web service, adding the service reference in another project thus creating a proxy class and using the methods.I have searched the internet and found that there is no native support for SwA in VB.NET, is this correct?

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:

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.

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.
