comparison operator

基本解释

std::pair has a comparison operator that does effectively the same comparisons as your version.
pair有一個比較運算符，跟你剛才寫的那個一樣。
These assertions work on user-defined types too, but you must overload the corresponding comparison operator (==, !=, so on).
這些斷言也適用於用戶定義的類型，但是必須覆蓋相應的比較操作符（==、! =、等等）。
Type a valid XPath expression (a reference on XPath is included in the Resources section following), a comparison operator (=, >, or and the expected number of nodes that the query should return.
鍵入一個有傚的 XPath 表達式（有關 XPath 的一個蓡考在下麪的蓡考資料部分中），一個比較運算符（=， >，或和查詢應該返廻的所期望的結點數。
