Reading XML files and load specify data into combo box

[edizone]

Hi all,

This is my first post in Tek-Tips forum, hope can get some helps and guides from you all..
My question sound like this:

I'm currently develop a window base applicationin c#. So far, I had create a xml files and plan to load the data into combo box accordingly base on the node name, example:

a) Sample of XML files:
**********************************************
<Material>
<C>Ceramic</C>
<L>Glass</L>
</Material>
<Position>
<A>Axial</A>
<B>Bottom</B>
<D>Dual</D>
</Position>
***********************************************

So, there will be two different combo box, one to store 'Material' and the other one to store 'Position', i want the data such as Ceramic, glass load into first combo box, and data such as "Axial", "Bottom" into second combo box,
how can i do that.

I used XML TextReader but seem like i can't specify which node to load, the code will give me the whole things(ceramic, glass, axial, bottom, dual), here is the code i used:

*************************************************
xtr = new XmlTextReader(fileName);
xtr.WhitespaceHandling = WhitespaceHandling.None;

while (xtr.Read())
{
switch (xtr.NodeType)
{
case XmlNodeType.Text: this.cboMaterial.Items.Add(xtr.Value); break;

}
}
***************************************************


Any help is appreciated, please help and thanks..

You also need to check for the <Material> and <Position> tags, which will tell you which combo box to load.

Hi thanks for your reply Miros..
Ya i know, but XmlTextReader class seem like cant validate xml data base on the tag name, i meant how could i know which tag to read on?

Try

http://msdn2.microsoft.com/en-us/library/system.xml.xmltextreader.aspx

Points it raises:

To perform data validation, use a validating XmlReader. For more information, see Validating XML Data with XmlReader.

To read XML data from an XmlDocument, use XmlNodeReader.

Also check

http://msdn2.microsoft.com/en-us/library/system.xml.xmltextreader.nodetype.aspx

. I think you just need to add another case to your switch:

HWND combobox = NULL ;
switch (xtr.NodeType)
{
    case XmlNodeType.Text:
        if ( combobox != NULL )
            combobox.Items.Add(xtr.Value);
        break;
    case XmlNodeType.Element: 
        if ( strcmp( xtr.Name, "Material" ) == 0 ) 
            combobox = this.cboMaterial ; 
        else if ( strcmp( xtr.Name, "Position" ) == 0 ) 
            combobox = this.cboPosition ;
        break ;
}
