简短的回答是:不要输出它。换句话说,不要声明它应该被输出到目标数据流中。
当您在转移规则的 模式 部分匹配两个或更多单词时,您可以选择在 输出 部分仅列出其中一些单词。
The short answer is don’t output it. In other words, don’t declare that it should be outputted into the target data stream.
When you match two or more words in the pattern section of a transfer rule, you can choose to only list some of the words in the output section.
