c# - Filter descendants parent [or at least higher level than results] -

still linq newbie here, , having issues clause. i'm trying return found in printer tags, below element list type="lff".

if try output descendant elements no clause, (from both <list> elements). when try add various versions of clause, nothing back. i'm not putting condition in correctly.

(i need element object, can check name , value. in example below, outputting value now).

can advise?

here xml:

<?xml version="1.0"?> <printerlist>   <list type="aff">     <printserver>print-server1</printserver>     <printserver>print-server2</printserver>     <printserver>print-server3</printserver>     <additionalprinters>       <printer>         <fullname>\\servera\bbb</fullname>       </printer>     </additionalprinters>   </list>   <list type="lff">     <printserver>print-sever4</printserver>     <additionalprinters>       <printer>         <fullname>\\serverb\bbb</fullname>       </printer>       <printer>         <fullname>\\serverc\aaa</fullname>       </printer>     </additionalprinters>   </list> </printerlist> 

and here code try , list:

var qq = c in xml.descendants("additionalprinters").descendants("printer") //where (string) c.parent.attribute("type") == "lff" //uncommenting above line means nothing returned. select c; foreach (xelement q in qq) {     console.writeline("test output: {0}", q.value ); } 

output is:

test output: \\servera\bbb test output: \\serverb\bbb test output: \\serverc\aaa 

i looking final 2 outputs returned, in particular case.

the parent of printer additionalprinters , doesn't have type property, need use .parent twice list element.

from c in xml.descendants("additionalprinters").descendants("printer") (string) c.parent.parent.attribute("type") == "lff" select c 

or can following

xml.descendants("list") .where(c => (string) c.attribute("type") == "lff") .selectmany(x => x.element("additionalprinters").descendants("printer"))
