从字符串中删除不必要的RTF数据 [英] Remove unnecessary RTF data from string
问题描述
我有一条RTF数据正在发送到我的应用程序，如下所示：
{\rtf1 \ sstecf22000\ansi\deflang2057\ftnbj\uc1\deff0
{\ tonttbl {\f0 \fnil \fcharset0 Microsoft Sans Serif;} {\f1 \fswiss Tahoma;}}

}
当我将其转换为纯文本时，仍会显示RTF数据。
<前la NG = XML> \ {\\Rtf1\\Ansi\\Deff0\ {\\Fonttbl\ {\\F0\\Fnil\\Fcharset0 Microsoft Sans Serif; \} \} \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ \ Par \ par \}
那么我如何检测并删除必要的RTF数据？：
\ {\\Rtf1 \\Ansi \\Deff0 \ {\\Fonttbl \ {\\\\\\\\ \\Fcharset0 Microsoft Sans Serif; \} \} \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ ... \\Par \ par \}
我试图使用rejex，但只检测RTF中的所有内容块我有。
例如
（{\\）（。+？）（}）|（\\\ ？\\）（+）（\b）|} $
我想只删除不必要的RTF数据。
以下是整个RTF数据块：
我的尝试：
我尝试使用以下代码尝试查看是否可以删除不必要的RTF数据，但我认为像这样指定的字符串是错误的。
string result = rtfString;
const string toLookFor = {\\Rtf1 \\Ansi\\Deff0 {\\Fonttbl {\\\\\\\\\\\\\\ Sans Serif;}} \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ n} \\\
text 3;
尝试
{
if （IsRichText（ rtfString））
{
if （rtfString.contains（toLookFor））
{
rtfString = rtfString.replace（ toLookFor， ）;
}
}
else
{
result = rtfString;
}
}
catch
{
throw < /跨度>;
}
返回结果;

使用Windows您可以使用RichText编辑控件将RTF转换为纯文本（只需在内存中创建它而不显示它并使用适当的函数来设置RTF并获取文本）。
C＃示例：如何：将RTF转换为纯文本（C＃编程指南） [ ^ ]。
使用Linux，您可以使用 unrtf（1） - Linux手册页 [ ^ ]工具或检查它源代码。
I have a piece of RTF data that is being sent to my application shown below:

When i convert it to plain text there is still RTF data being displayed.
\{\\Rtf1\\Ansi\\Deff0\{\\Fonttbl\{\\F0\\Fnil\\Fcharset0 Microsoft Sans Serif;\}\}\par \\Viewkind4\\Uc1\\Pard\\Lang2057\\F0\\Fs17 Cup....\\Par\par \}
So how would i detect and remove the necessary RTF data?:
\{\\Rtf1\\Ansi\\Deff0\{\\Fonttbl\{\\F0\\Fnil\\Fcharset0 Microsoft Sans Serif;\}\}\par \\Viewkind4\\Uc1\\Pard\\Lang2057\\F0\\Fs17 Cup....\\Par\par \}
I tried to use rejex but that only detects everything in the RTF block that i have.
e.g
({\\)(.+?)(})|(\\)(.+?)(\b)|}$
I want to remove only the unnecessary RTF data.
Here is the entire RTF block of data:
What I have tried:
I tried to use the following code to try and see if i can remove the unnecessary RTF data but i think having the string specified like this is wrong.
string result = rtfString;
const string toLookFor = "{\\Rtf1\\Ansi\\Deff0{\\Fonttbl{\\F0\\Fnil\\Fcharset0 Microsoft Sans Serif;}}\n\\Viewkind3\\Uc1\\Pard\\Lang2057\\F0\\Fs17 Cup....\\Par\n}\ntext 3";
try
{
if (IsRichText(rtfString))
{
if(rtfString.contains(toLookFor))
{
rtfString = rtfString.replace(toLookFor, "");
}
}
else
{
result = rtfString;
}
}
catch
{
throw;
}
return result;

With Windows you can use a RichText edit control to convert RTF to plain text (just create it in memory without displaying it and use the appropriate functions to set RTF and get text).
C# example: How to: Convert RTF to Plain Text (C# Programming Guide)[^].
With Linux you can use the unrtf(1) - Linux man page[^] tool or check it's source code.
