Re: how to fetch child nodes of parent node in XML .. using c#...

14-Nov-07 5:02

Well I have some suggestions for you.

First I recommend, it's what I use, www.w3schools.com as an excellent reference for things like XPath etc.

Second, find yourself a method of testing XPath statements before you try to integrate them into code. I mean you just type a statement and execute it in some environment to see that you obtain the node or node set desired. There might be something you can get for free and it's not that difficult to write a little command line utility or even a Windows Forms application for testing XPath statements.

Lastly, when you want to create a paramaterized XPath statement don't use string concatination, use String.Format(...) with format strings that have placeholders for the parameters. It's far simpler to get the XPath statement syntax correct when you do that. Let's use your statement as an example:

"/LinkInformation/ScreensToSupport/ScreenToSupport/[ScreenUniqueId='"+strScreenId+"']";<br />

The format string would be:

"/LinkInformation/ScreensToSupport/ScreenToSupport/[ScreenUniqueId='{0}']";

then use it in String.Format and pass the parameter to fill in the placeholder.

Now to your problem. You XPath statement syntax is incorrect, there should be no path separator before the expression

ScreenToSupport/[ScreenUniqueId

should be

<br />
ScreenToSupport[ScreenUniqueId

You need to read the documentation, and there are a lot of examples available on Code Project and the rest of the internet. Anyways, here is an example:

using System;
using System.Xml;

namespace XmlExample
{
class Program
{
static void Main(string[] args)
{
string xml =
"<?xml version='1.0'?>\n"
+ "<nodes>\n"
+ "\t<node/>\n"
+ "</nodes>\n";

XmlDocument xml_doc = new XmlDocument();
xml_doc.PreserveWhitespace = true;
xml_doc.LoadXml(xml);

XmlNode node = xml_doc.SelectSingleNode("//nodes/node");

if (node != null)
{
XmlText text = xml_doc.CreateTextNode("Hello, World!");
node.AppendChild(text);
}

Console.WriteLine(xml_doc.InnerXml);
}
}
}

Use an XPath statement to find the node you want to remove then call

node.ParentNode.RemoveChild(node)<br />
<br />

XmlNode node = doc.SelectSingleNode("//x/y/z/ScreenSupportItem");
node.ParentNode.RemoveChild(node);

12-Nov-07 22:22

Hello sir

There is a little problem of xml again.
How can I go through all child nodes and attributes of child nodes of a parent node..

Suppose i have to go through all child nodes e.g.<ScreenSupportItem> of parent nodes

e.g.<SupportItems>. There can be mutiple <ScreenSupportItem> in a parent node <SupportItems>. I have

to check values of <LinkURL> and <LinkText> of all child nodes <ScreenSupportItem> and if it matches

with the supplied valus it gives a message 'LinkUrl/LinkText already exist' else insert new

<ScreenSupportItem> of <ScreenSupportItem> and set all attributes of <ScreenSupportItem> , which was

supplied by the user.
My code check only first child <ScreenSupportItem> of <SupportItems> if it values matches for

<LinkURL> and <LinkText> give a proper message else insert new <ScreenSupportItem>.
So how can I check all child <ScreenSupportItem> for values <LinkURL> and <LinkText> of

<SupportItems>

As the error message explains, you are adding a node as a child of itself here. Read the MSDN documentation[^] on this method if you are unsure how to use it.

Sending XML Soap Messages, C#

am writing an app that uses the .Net classes TCPClient and NetworkStream to read and write data between 2 machines. All works fine.

I have recently found a need to be able to send Http 1.1 with a SOAP message as the Http body. Currently i am using an XmlDocument to load and parse the SOAP data. However to do this i first have to read in the HTTP header, search for the beginning of the body and construct my own XmlDocument.

There must be a better way. I don't want to call a web service, i just want to send http with a soap body and receive the same.

I am looking for a means of loading in the NetworkStream into some kind of HTTP object to read the http stuff and also load the body into some simple Soap object that can be used to pull out/ set values.

Comments, Suggestions Welcomed.

It appears you are not having a problem with XML but with an ASP.NET Datagrid.

My problem is I could not filter the data appears in my second datagrid. Because when i load my xml file it will simply populate the two datagrid. My first datagrid is consist of Parent nodes while my second datagrid are the child nodes.
What i want to do is when i load the xml file the first datagrid will display all data while the display data in the second datagrid depends on the first grid.HOw could I filter the data in the second grid?
