在主题重写功能开启的前提下，EMQX 在收到诸如 PUBLISH 报文等带有主题的 MQTT 报文时，将使用报文中的主题去依次匹配配置文件中规则的主题过滤器部分，一旦成功匹配，则使用正则表达式提取主题中的信息，然后替换至目标表达式以构成新的主题。 在主题重写功能开启的前提下，EMQX 在收到诸如 PUBLISH 报文等带有主题的 MQTT 报文时，将使用报文中的主题去依次匹配配置文件中规则的主题过滤器部分，一旦成功匹配，则使用正则表达式提取主题中的信息，然后替换至目标表达式以构成新的主题。
目标表达式中可以使用 `$N` 这种格式的变量匹配正则表达中提取出来的元素，`$N` 的值为正则表达式中提取出来的第 N 个元素，比如 $1 即为正则表达式提取的第一个元素。 目标表达式中可以使用 `$N` 这种格式的变量匹配正则表达中提取出来的元素，`$N` 的值为正则表达式中提取出来的第 N 个元素，比如 `$1` 即为正则表达式提取的第一个元素。
需要注意的是，EMQX 使用倒序读取配置文件中的重写规则，当一条主题可以同时匹配多条主题重写规则的主题过滤器时，EMQX 仅会使用它匹配到的第一条规则进行重写，如果该条规则中的正则表达式与 MQTT 报文主题不匹配，则重写失败，不会再尝试使用其他的规则进行重写。 需要注意的是，EMQX 使用倒序读取配置文件中的重写规则，当一条主题可以同时匹配多条主题重写规则的主题过滤器时，EMQX 仅会使用它匹配到的第一条规则进行重写，如果该条规则中的正则表达式与 MQTT 报文主题不匹配，则重写失败，不会再尝试使用其他的规则进行重写。
