Obtain XML Values

The way i am doing it in my own code at the moment is this:

1. Obtain the XML file using the httpwebrequest and httpwebresponse methods to query the URL
2.  Save the incoming stream into a text file with the xml extension (the incoming stream is actually in xml format)
3. Use an XMLReader.Create construct to open an XMLReader with the file you just obtained as the source.  Then you can use the reader to move around the XML file node-by-node.

Information can be found here:

XML general http://www.w3schools.com/xml/default.asp
HttpWebRequest and WebResponse http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest(VS.71).aspx and http://msdn.microsoft.com/en-us/library/system.net.httpwebresponse(VS.71).aspx
XMLReader http://msdn.microsoft.com/en-us/library/9d83k261.aspx

Instead of area desc I am attempting to get title, although it's not working... I am trying "default:entry/title"

<?xml version = '1.0' encoding = 'UTF-8' standalone = 'yes'?>
<?xml-stylesheet href='capatom.xsl' type='text/xsl'?>

default:entry/default:title works
Thanks

If you notice, title isn't a child element of entry. Also, for any elements that don't have a prefix (ie. title vs. cap:areaDesc), you need use the prefix default. Hence, you would use
"default:title" as the XPath query.

Just posted after you accepted the answer, my previous post was for the 1st title element, rather than the one in the entry element. But already had worked it out.
