Hello,
I'm going to learn how to make an easy XML Writer ( It will add new nodes)
XML file

Code: Select all

<products>
  <product>
    <id>1</id>
    <name>Ipod Touch 4</name>
    <price>200</price>
    <btw>21</btw>
  </product>
  <product>
    <id>2</id>
    <name>Itunes Store Card €15</name>
    <price>15</price>
    <btw>21</btw>
  </product>
</products

Then first of all make sure u put:

Code: Select all

Imports System.XML

at the top
I added 4 labels: ID,Product name, Price and Btw , a numeric Up and Down , 2 textboxes and a combobox ( items: 0,6,12,21)

then a button and then the code of the button:)

then dim the document:

Code: Select all

Dim XmlDoc As New XmlDocument

Then we are going to load the document:

Code: Select all

XmlDoc.load("Products.xml")

then the writing

Code: Select all

XmlDoc.SelectSingleNode("/products").InnerXml &= "<product><id>" & NumericUpDown1.Value & "</id><name>" & TextBox1.Text & "</name><price>" & TextBox2.Text & "</price><btw>" & ComboBox1.Text & "</btw></product>"
'selects the first node were all the product nodes are in and adds to the bottom a new node with innerxml.
        XmlDoc.Save("Products.xml")
'saves document
        MsgBox("Added", MsgBoxStyle.Information, "Info")
'show msgbox completed
        NumericUpDown1.Value = (NumericUpDown1.Value + 1)
        TextBox1.Clear()
        TextBox2.Clear()
        ComboBox1.Text = ""
'clears inputs ;)

and this is it

Not that I didn't understand it, but would you make the code easier to understand? Maybe put some comments? But I thought there was this XMLWriter class to do such things. Just saying.
But good job

oh give me a second

Code: Select all

XmlDoc.SelectSingleNode("/products").InnerXml &= "<product><id>" & NumericUpDown1.Value & "</id><name>" & TextBox1.Text & "</name><price>" & TextBox2.Text & "</price><btw>" & ComboBox1.Text & "</btw></product>"

Like the document this is a the node we will add:

Code: Select all

<product>
<id>-</id>
<name>-</name>
<price>-</price>
<btw>-</btw>
</product>

Then we will putt our values in it so:

Code: Select all

<product>
<id>" & NumericUpDown1.Value & "</id>
<name>" & TextBox1.Text & "</name>
<price>" & TextBox2.Text & "</price>
<btw>" & ComboBox1.Text & "</btw>
</product>

Then put it under the last <product></product>

Code: Select all

XmlDoc.SelectSingleNode("/products").InnerXml &= "<product><id>" & NumericUpDown1.Value & "</id><name>" & TextBox1.Text & "</name><price>" & TextBox2.Text & "</price><btw>" & ComboBox1.Text & "</btw></product>"

and then save

Code: Select all

XmlDoc.save
