Answer 1

이 (안된) 같은 것을보십시오 :

var doc = XDocument.Parse(xmltext); 
var selectedRegion = doc.Root.Descendents("region").FirstOrDefault(r => r.Attribute("section").Value == "target value"); 

Answer 2

사용 :

var result = XDocument.Parse(input).Descendants("region") 
    .FirstOrDefault(e => (string)e.Attribute("section") == "CityServices"); 

또는 사용의 XPath :

//region[@section = 'CityServices']
