Reading a value from XMLDatasource

I have a ComboBox which is bound to a XmlDatasource. The XML has 3
attributes: name, location, value. I have name and location bound to the
ComboBox.

Now what I want to do is get the name/location for the node with value = 9.

It doesn't seem like the XmlDatasource has any methods for iterating over
the nodes.

Is there any easy way to do this?

The XMl is simple:
<Parent>
<child name="" location="" value=""/>
<child name="" location="" value=""/>
<child name="" location="" value=""/>
</Parent>

Thanks,
Joe
 
Hi Joe,

For the the following requirement you mentioned:
Now what I want to do is get the name/location for the node with value = 9.
<<<<<

do you mean you want to programmatically in code to extract the certain XML
Node from the XmlDataSource's data (xml document)? If so, you can use the
"GetXmlDocument" method to get the in-memory xml content and perform Xpath
query to extract the values. e.g.

===================
protected void Page_Load(object sender, EventArgs e)
{
XmlDocument doc = XmlDataSource1.GetXmlDocument();

XmlNodeList nodes = doc.SelectNodes("//child[@value='9']");

foreach (XmlNode node in nodes)
{
Response.Write("<br/>name: " + node.Attributes["name"].Value +
", location: " + node.Attributes["location"].Value);
}
}
======================

If you have any more specific concern, please feel free to post here.
