在 PHP 中连接 RTF 文件 (REGEX)
我有一个脚本，它接受用户上传的 RTF 文档并将一些个人数据合并到信件中（姓名、地址等），并为多人执行此操作。 我合并信件内容，然后将其与下一个合并信件内容合并，以供所有人记录。
实际上，我将单个 RTF 文档合并到其自身中，以容纳我需要将信件合并到的尽可能多的人员记录。 但是，我需要首先删除每个合并的关闭 RTF 标记和打开 RTF 标记，否则 RTF 将无法正确呈现。 这听起来像是正则表达式的工作。
本质上我需要一个正则表达式来删除整个字符串：
}\n\page ANYTHING \par
示例，这个正则表达式将与此匹配：
crap
}
\page{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fswiss\fcharset0 Arial;}}
{\*\generator Msftedit 5.41.15.1515;}\viewkind4\uc1\pard\f0\fs20 September 30, 2008\par
more crap
所以我可以使它只是：
crap
\page
more crap
RegEx 是这里最好的方法吗？
更新：为什么我必须使用 RTF？
我想让用户上传一封套用信函，然后系统将使用该套用信函创建合并的信函。 由于 RTF 是纯文本，因此我可以在代码中轻松完成此操作。 我知道，RTF 是一个灾难性的规范，但我不知道还有其他好的选择。
I've got a script that takes a user uploaded RTF document and merges in some person data into the letter (name, address, etc), and does this for multiple people. I merge the letter contents, then combine that with the next merge letter contents, for all people records.
Affectively I'm combining a single RTF document into itself for as many people records to which I need to merge the letter. However, I need to first remove the closing RTF markup and opening of the RTF markup of each merge or else the RTF won't render correctly. This sounds like a job for regular expressions.
Essentially I need a regex that will remove the entire string:
}\n\page ANYTHING \par
Example, this regex would match this:
crap
}
\page{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fswiss\fcharset0 Arial;}}
{\*\generator Msftedit 5.41.15.1515;}\viewkind4\uc1\pard\f0\fs20 September 30, 2008\par
more crap
So I could make it just:
crap
\page
more crap
Is RegEx the best approach here?
UPDATE: Why do I have to use RTF?
I want to enable the user to upload a form letter that the system will then use to create the merged letters. Since RTF is plain text, I can do this pretty easily in code. I know, RTF is a disaster of a spec, but I don't know any other good alternative.

我对在这种情况下使用 RTF 表示质疑。 我并不完全清楚你总体上想要做什么，所以我不一定能提出更好的建议，但如果你可以尝试更广泛地解释你的项目，也许我可以提供帮助。
如果这确实是您想要的方式，则根据您的输入，此正则表达式为我提供了正确的输出：
I would question the use of RTF in this case. It's not entirely clear to me what you're trying to do overall, so I can't necessarily suggest anything better, but if you can try to explain your project more broadly, maybe I can help.
If this is really the way you want to go though, this regex gave me the correct output given your input:
对此我可以说太恶心了。 尽管如此，rcar 的 cludge 可能会起作用，除非有一些奇怪的边缘情况，即 RTF 实际上并不以这种形式结尾，或者文档范围的样式包含完全混乱格式的重要信息，或者任何其他许多失败模式。
To this I can say ick ick ick. Nevertheless, rcar's cludge probably will work, barring some weird edge-case where RTF doesn't actually end in that form, or the document-wide styles include important information that utterly messes up the formatting, or any other of the many failure modes.
