I am using a third party Web Service application that I can obtain a status from by navigating to a web address and port and I receive an XML result similar to this;

solutionsville:

 

I want to take the value of the <state></state> field and post it to cell of a table automatically when the web site is opened, and refreshed every 300 seconds.

 

What is the best way to do this?

 

Thanks!

To read the value from node state u can use xmlDom or write a simple xslt which does xml to html transformation.

Now if u want to update this value every 300 seconds then u have to write a schedular that runs every 300 seconds..then it calls this web service and does the autorefresh to ur UI.

 XPathDocument doc = new XPathDocument("http://example.com/service");

string state = doc.SelectSingleNode("always-up-get-status-response/applications/application/state").Value;

Label1.Text = state;

Put a Label control in your table cell and put the above code into the Page_Load handler.

The doc.SelectSingleNode item does not exist.

With the XPathDocument doc declaration, it has five overloads. None of which are for selecting a specific node entry.

Unless I am way off the mark.

Thanks,

 I am sorry, SelectSingleNode is defined on XPathNavigator, not on XPathDocument so you need

XPathDocument doc = new XPathDocument("http://example.com/service");

string state = doc.CreateNavigator().SelectSingleNode("always-up-get-status-response/applications/application/state").Value;

Label1.Text = state;

Thanks, that worked fine with the excpetion of I missed that the node item was not correct. Here is what it should look like;

string state = doc.CreateNavigator().SelectSingleNode("alwaysup-get-status-response/applications/application/state").Value;

Thanks for the help.
