Free ASP.NET 4.5 Cloud Hosting Spain - HostForLIFE.eu :: Count Number of Nodes in XML File in ASP.NET 4.5

clock May 6, 2014 06:00 by author Peter

Here I will explain how to count number of records in xml file in C# using ASP.NET 4.5 Cloud Hosting Spain or how to count number of nodes in xml file in asp.net using C# and VB.NET or count number of elements in xml file in C#.

In previous articles I explained insert xml data to sql table using stored procedure, Bind xml data to dropdown/gridview in asp.net, create online poll system with percentage graphs in asp.net and many articles relating to xml, Gridview, SQL, jQuery,asp.net, C#,VB.NET. Now I will explain how to count number of records in xml file in C# using ASP.NET.

To count number of nodes from xml file we need to write the code like as shown below

XmlDocument readDoc = new XmlDocument();
readDoc.Load(MapPath("Sample.xml"));
int count = readDoc.SelectNodes("CommentsInformation/Comments").Count;
lblcount.InnerHtml = "Number of Records: "+ count;

If you want to see it in complete example we need to write the code like as shown below
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<table>
<tr>
<td style="width: 100px">
Name:</td>
<td style="width: 100px">
<asp:TextBox ID="txtName" runat="server"></asp:TextBox></td>
</tr>
<tr>
<td style="width: 100px">
Email:</td>
<td style="width: 100px">
<asp:TextBox ID="txtEmail" runat="server"></asp:TextBox></td>
</tr>
<tr><td></td>
<td>
<asp:Button ID="btnSubmit" runat="server" OnClick="btnSubmit_Click" Text="Submit" /></td>
</tr>
</table>
<br />
<label id="lblcount" runat="server" />
</div>
</form>
</body>
</html>

After that add XML file to your application and give name as "Sample.xml" then add root element in xml file otherwise it will through error. Here I added CommentInformation as root element in XML file.
<?xml version="1.0" encoding="utf-8"?>
<CommentsInformation>
 </CommentsInformation>

After that add this namespace in codebehind

C# Code
using System;
using System.Xml;

After that add below code in code behind

protected void Page_Load(object sender, EventArgs e)
{
}
protected void btnSubmit_Click(object sender, EventArgs e)
{
XmlDocument xmldoc = new XmlDocument();
xmldoc.Load(Server.MapPath("Sample.xml"));
XmlElement parentelement = xmldoc.CreateElement("Comments");
XmlElement name = xmldoc.CreateElement("Name");
name.InnerText = txtName.Text;
XmlElement email = xmldoc.CreateElement("Email");
email.InnerText = txtEmail.Text;

parentelement.AppendChild(name);parentelement.AppendChild(email);
xmldoc.DocumentElement.AppendChild(parentelement);
xmldoc.Save(Server.MapPath("Sample.xml"));
XmlDocument readDoc = new XmlDocument();
readDoc.Load(MapPath("Sample.xml"));
int count = readDoc.SelectNodes("CommentsInformation/Comments").Count;
lblcount.InnerHtml = "Number of Records: "+ count;
}

VB.NET Code
Imports System.Xml
Partial Class vbcode
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
End Sub
Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As EventArgs)
Dim xmldoc As New XmlDocument()
xmldoc.Load(Server.MapPath("Sample.xml"))
Dim parentelement As XmlElement = xmldoc.CreateElement("Comments")
Dim name As XmlElement = xmldoc.CreateElement("Name")
name.InnerText = txtName.Text
Dim email As XmlElement = xmldoc.CreateElement("Email")
email.InnerText = txtEmail.Text
parentelement.AppendChild(name)
parentelement.AppendChild(email)
xmldoc.DocumentElement.AppendChild(parentelement)
xmldoc.Save(Server.MapPath("Sample.xml"))
Dim readDoc As New XmlDocument()
readDoc.Load(MapPath("Sample.xml"))
Dim count As Integer = readDoc.SelectNodes("CommentsInformation/Comments").Count
lblcount.InnerHtml = "Number of Records: " & count
End Sub
End Class
