    copied!<p>I realize this is a repost but I needed to as I can't use LINQ, ( requested in my previous post). </p> <p>I need to read the woeid from the XML doc below. I need to read and store the data into a string variable so I can query the yahoo weather service.</p> <p>XML returned by query:</p> <pre><code>&lt;query yahoo:count="1" yahoo:created="2009-12-22T08:30:31Z" yahoo:lang="en-US" yahoo:updated="2009-12-22T08:30:31Z" yahoo:uri="http://query.yahooapis.com/v1/yql?q=select+woeid+from+geo.places+where+text%3D%22farnborough%2C+greater+london%2Cuk%22"&gt; &lt;diagnostics&gt; &lt;publiclyCallable&gt;true&lt;/publiclyCallable&gt; &lt;url execution-time="32"&gt; http://where.yahooapis.com/v1/places.q(farnborough%2C%20greater%20london%2Cuk);start=0;count=10 &lt;/url&gt; &lt;user-time&gt;33&lt;/user-time&gt; &lt;service-time&gt;32&lt;/service-time&gt; &lt;build-version&gt;4265&lt;/build-version&gt; &lt;/diagnostics&gt; &lt;results&gt; &lt;place&gt; &lt;woeid&gt;19941&lt;/woeid&gt; &lt;/place&gt; &lt;/results&gt; &lt;/query&gt; </code></pre> <p>Can someone suggest how I could do this through XPath or another way which is compatible with the libraries in .net 2.0?</p> <p>Thanks for the answers. As such I am using the method below, but I get an exception thrown when loading the XML document:</p> <pre><code>private string getWOEID(string UserLocation, string UserCountry) { string woeID = ""; if (UserLocation == "farnborough") { UserLocation = "farnborough" + "%2C" + "hampshire"; } String reqUrl = "http://query.yahooapis.com/v1/public/yql?q=select%20woeid%20from%20geo.places%20where%20text%3D%22" + UserLocation + "%2C" + UserCountry + "%22&amp;format=xml"; XmlDocument doc = new XmlDocument(); doc.LoadXml(reqUrl); string woeid = doc.SelectSingleNode("query/results/place/woeid/text()").Value; return woeID; } </code></pre>
 

Querying!
