ASP.NET 2.0: how to use XPath?

Question

Hello guys:

If we can get a collection of x nodes via XPath in ASP.NET 2.0? Then doing checking per the attrs of them.

<x-list>
  <x id="1" enable="On" url="http://abc.123.dev"/&gt;
  <x id="2" enable="Off" url="http://asd.com"/&gt;
  <x id="3" enable="On" url="http://plm.xcv.tw"/&gt;
</x-list>

Thanks for any help. Ricky

Answer 1

I would recomment you using the XML Web Server Control.

Answer 2

Here's a sample that'll retrieve all of your 'x' nodes that are enabled:

XmlNodeList nodes = root.SelectNodes("/x-list/x[@enable='On']");
foreach (XmlNode node in nodes)
{
  ...
}

I find w3schools a good place to look for XPath tutorials.

Answer 3

XmlDocument xDocument = new XmlDocument();
xDocument.LoadXml(xmlString);

XmlNodeList xList = xDocument.SelectNodes("x-list/x");

if (xList.Count > 0)
{
 foreach (XmlNode x in xList)
     {
         string id = x.Attributes["id"].Value;
  string enable = x.Attributes["enable"].Value;
  string url = x.Attributes["url"].Value;

  if (enable.Equals("On")
  {
   ...
  }
  else
  {
   ...
  }

 }
}
else
{
...
}
