attributes - How to find XElement specific Children (in c# with LINQ)? -


i've got xml file :

<root>  <environment env="prod">   <key name="big key" propagate="true" value="21" />  </environment>  <environment env="pre-prod">   <key name="first key" propagate="true" value="4" />   <key name="second key" propagate="true" value="3" />  </environment> </root>

i want check if key exist in file, , if propagate item true. manage 2 system.xml.linq.xelement : key name="first key" , key name="second key". get 1 pkeyname (like "second key" eg.) can't find how...

public static bool ispropagate(string pxmlfilename, string penvironment, string pkeyname) { var doc = xelement.load(pxmlfilename); ienumerable<xelement> childlist = doc.elements("environment") .where(elt => elt.attribute("env").value == penvironment) .elements();  if (childlist.any()) return true; return false; }

any highly appreciated!

this exact key:

       public static bool ispropagate(string pxmlfilename, string penvironment,                                        string pkeyname)         {             var doc = xelement.load(pxmlfilename);             ienumerable<xelement> childlist = doc.elements("environment")             .where(elt => elt.attribute("env").value == penvironment)             .elements()             .where(a => a.attribute("name").value == pkeyname);              if (childlist.any())                 return true;             return false;         }
