Question

How do I check an xml file to determine if some elements exist? For example I have the XML from:

http://www.google.com/ig/api?weather=vilnius&hl=eng

I want check if the word “wind_condition” exists:

if ("wind_condition") {do something}

Answer 1

This will determine if the file contains the word wind_condition.

if(xml.ToString().Contains("wind_condition"))
{
    // do something
}

In case you want the element wind_condition

if(xml.Descendants("wind_condition").Count() > 0)
{
    // do something
}
