Javascript和PHP正则表达式，用于捕获在相关收件人字段中找到的电子邮件地址

我正在尝试开发两个正则表达式，一个是javascript，另一个是php，它将捕获原始电子邮件中的电子邮件地址，这些地址只与各自的字段相关，例如to:和only it's field，即语料库中没有来自其他任何地方的其他电子邮件，但我没有成功

以下是理想的要求：

必须从新行开始，从该行的开头开始

新行必须以To开头，例如，双引号除外，不区分大小写，单个冒号是可选的，单个或无限数量的空格是可选的

必须捕获此后的所有电子邮件地址，单独捕获，直到最后一个电子邮件地址，但在非电子邮件地址词之前捕获非电子邮件地址词的示例，但不具体捕获：主题：、发件人：、抄送：、你好等

我在需求1和需求2方面取得了成功，但在需求3方面遇到了困难。我被迫简单地求解1和2，并简单地根据逗号拆分/分解结果，这很好，但我知道可以得到更好的结果

这是一封来自安然电子邮件pulic数据集的电子邮件示例

February 10, 1999

I am wakened by the approaching chatter of the early morning call to
prayer (sounding a bit like the fuss made by one of those cartoon balls
of fighting dogs and cats).  From the minarets of far away mosques, the
muezzins' cries ricochet through Istanbul's still dark alleys and
streets.  Seagulls, who have drifted up the hill from the Golden Horn,
squawk contentedly outside my window.  From somewhere down below, a
miserable dog joins into the pre-dawn ruckus, soon followed by the local
muezzin, whose amplified singing drowns out all the rest.  He reminds us
that God is great and that prayer is a whole lot more important than
sleep (at least that's what I've been told; he sings in Arabic).
Because my religion thinks more highly of sleep, I feel free to simply
listen, while gently trying to pull the warm blanket of sleep back over
me.  The  muezzin has a beautiful voice.  Its rise and fall stitches
itself into the edges of a dream (in which a former best friend and I
argue about the rules of a game of miniature golf) hanging just out of
reach.

Slowly, the banal calculations that fill my days begin to crowd their
way into my head.  It's about a quarter to six, I figure, which means
there's time for a bit of writing, or even Turkish vocabulary, before I
douse myself in the shower to full consciousness.  I remind myself of
the theory that one can write most freely while still intoxicated with
sleep (or just plain intoxicated), am immediately stricken with the fear
I am incapable of such freedom, take a look round my brain for something
worth writing about (find nothing), hypothesize about the advantages of
a quick dash into the hallway to turn on the gas heater (so that when I
really get up it will be reasonably warm out there), wonder if I really
do have enough stuff prepared to fill up the two hours of my English
lesson with Suleyman, conclude that all this thinking has probably made
any more sleep impossible, then (I realize later) fall back to sleep.

                               *     *     *

My new phone [(212) 292-6486] is hooked up and I have a new internet
server, which will make it much easier to keep in touch.  Hope to attack
that backlog of responses that are due.

Keep in touch.

谢谢你的帮助。 希望这能让其他搜索者受益！：

下面是我当前使用的正则表达式，它满足要求1和2，并返回特定字段的收件人blob：

/^(?:To:?(?:\s+)?)((?:(?:(?:(?:[^<>()[\]\\.,;:\s@\"]+(?:\.[^<>()[\]\\.,;:\s@\"]+)*)|(?:\".+\"))@(?:(?:\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(?:(?:[a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))),?\s+)+)+/mi;

---

求解完1和2之后，您可以使用此选项从所选内容中获取任何电子邮件地址

[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})

这应该抓住任何有效的电子邮件地址和赢得；不要抓取无效的，如：example@gmail...com

这是来自公共域中存在的数据集；这些都是很好的例子。这几乎就像用一块砖头，知道外面最好把钉子钉在墙上。我们同意这个解决方案已经足够了，但我知道还有更好的解决方案，这个场地将帮助我找到它。我在家得宝的中间，有人一定要找到我的锤子。此外，精炼平台也是如此。为什么你认为正则表达式比简单地匹配一个点然后拆分要好，而不是尝试使用递归正则表达式来捕获每个电子邮件地址？我的目标是在一次操作中检索所需的结果。你的尝试在哪里？我知道您的“理想需求”是什么，尽管我没有看到您尝试过的任何代码。可能，但我宁愿在解决1和2的问题时这样做。通过此电子邮件验证表达式：[^[]\\.；：\s@\]+\.[^[]\.；：\s@\]+*.+\[[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[a-zA-Z-0-9]+.+.[a-zA-Z]{2，}
