Retrieving A Single Node Anywhere In An XML string

Posted By:      Posted Date: October 10, 2010    Points: 0   Category :ASP.Net

I have an XML string containing a Node named Code. I try to obtain the node using the following code:

XmlDocument doc = new XmlDocument();

doc.LoadXml("<Message version="1.5" xmlns="http://www.testingxml.com/messaging"><Header><To>mailto:EMEDSL.dp@testingxml.com</To><From>mailto:SDEDIR.dp@testingxml.com</From><MessageID>0</MessageID><RelatesToMessageID>634223224036548000</RelatesToMessageID><SentTime>2010-10-10T19:46:35.9Z</SentTime></Header><Body><Error><Code>900</Code><DescriptionCode>902</DescriptionCode><Description>HRA must be populated with valid data only.</Description></Error></Body></Message>");

XmlElement xe = doc.DocumentElement;

XmlNode xmlnode1 = xe.SelectSingleNode("//Code");

xmlNode1 is always null.

How to display TreeViewItems different ways based on the item type under a single node?

Hi, I am having trouble trying to display hiearchical data under each node in two different ways depending on the data.  I hope someone will be able to provide me some help on this since I am rather new to WPF development. Maybe I am going about this all wrong but for now, I am trying to create a customized TreeView to represent data similar to the xml I provided in the code below.  The <ItemsPresenter/> instances listed in the code are not exactly doing what I need.  I will probably need to filter the content that I list with each of the two <ItemsPresenter/> tags based on the type of each item although I have no idea if this is possible.   <Window x:Class="Wpf_treeview_testing.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300"> <!-- * The "xmlData" describe roughly the type of data that I require visual representaion of. * Since I could not find a WPF Control that will present a Hierachical Data Template close to what we need, I am trying to setup a TreeView to represent this information by using a ControlTemplate for TreeViewItem. * The preferred result is to present different items types in

how to get node containing a value - out of whole XML string


Hi, I have this XML string.

<xml version="1.0" encoding="utf-16">
    <x> test value 1 </x>
    <y> test value 2</y>

        <x> test value 3</x>
        <y> test value 4</y>

                <x> test value 5</x>
                <y> test value 6 </y>




As per the above sample XML, I have the same object hierarchy in this xml file.

Now out of all of these xml, I want to find a particular node <x> ofwhich value is "Test value 5".

This node can be anywhere in the hierarchy but I know that its value will be unique.

so I want to find <x> node out of this XML containing value "Test Value 5" and I need to update that value as well.

Which is the best way to do this and what is the syntex to get that node?

Thanks in advance

Where is the value stored in the Single and String structure in .Net framework?


I'm curious and want to know how or where is the value stored in the Single and String structure. Is it stored in a variable that is a member of the Single or String structure or is it stored in a function which returns the value that is stored. I'm curious how a structure can return a value that was stored for example:

Single single;

single = 5;

float* single_ptr;

single_ptr = &single;

abstract away the source of the connection string using a class with a static property.

ASP.NET provides a configuration system we can use to keep our applications flexible at runtime. In this article we will examine some tips and best practices for using the configuration system for the best results.

The element of a web.config file is a place to store connection strings, server names, file paths, and other miscellaneous settings needed by an application to perform work. The items inside appSettings are items that need to be configurable depending upon the environment, for instance, any database connection strings will change as you move your application from a testing and staging server into production.
