I try to extract specific data from an xml feed that comes from youtube.

XML link: http://gdata.youtube.com/feeds/api/videos/WFPnl8aEPgo?alt=rss

I’ve been able to extract info like:

Title,
Description

using this query string:

Dim Title As String =
videoInfoNavigator.SelectSingleNode(“/item[1]/title”).Value

However, I’m not able to find the proper query string to get info like

media:keywords

    The media:keywords use the media namespace prefix, which is bound to the namespace-uri http://search.yahoo.com/mrss/

    If you can register the namespace prefix, you could use an XPATH like this:

    /item[1]/media:group/media:keywords

    However, if you need a more generic XPATH that does not rely on the namespace prefix, you could express it like this: 

    /item[1]/*[local-name()='group' and namespace-uri()='http://search.yahoo.com/mrss/']/*[local-name()='keywords' and namespace-uri()='http://search.yahoo.com/mrss/']

    Applied to your example code:

    Dim Keywords As String = videoInfoNavigator.SelectSingleNode("/item[1]/*[local-name()='group' and namespace-uri()='http://search.yahoo.com/mrss/']/*[local-name()='keywords' and namespace-uri()='http://search.yahoo.com/mrss/']").Value
