if want "entry" element value of "example" or other incomplete value how do ?

thank you

var example = xdocument.parse(instr)                    .descendents("entry")                    .where(e => e.element("url").value.contains("example"))                    .firstordefault();

if there more 1 possible element may not want .firstordefault()
