使用findText在Google App脚本(documentApp)中使用正则表达式拆分文本 [英] splitting up text with a regular expression in google app script (documentApp) with findText

问题描述

在Google文档(而不是电子表格)中，有一堵看起来像

In a google doc (not a spreadsheet) I have a wall of text that looks like

 °foo bar header°foo bar bat paragraph°and another paragraph°and yet an other paragraph°and so on

，我想将文本分成几段.

and I want to split up the text into paragraphs.

所以我想借助正则表达式在°字符之间获取文本.我想使用

So I would like to get the text between the ° chars with help of a regexp. I would like to use

     var rangeElement = body.findText("°([^°]*)°");

但是该正则表达式使Google文档变为服务不可用:文档".使用像"°.?°"这样的正则表达式可以缓解该问题，但不能隔离我想要的文本.

but that regexp makes google docs go "Service unavailable: Docs". Using a regexp like "°.?°" alleviates that problem, but does not isolate the text I want.

什么是有效的正则表达式?如何从(和)内部处理子字符串?

What is a regexp that would work? How can I proceed to process the substring from within the ( and )?

推荐答案

要获取所有(多个)匹配项，可以将JavaScript RegExp与g(全局)修饰符一起使用.

To get all (multiple) matches, you can leverage the JavaScript RegExp witha g (global) modifier.

var rx = /°([^°]*)/g;
while (m=rx.exec(doc.getBody().getText())) { 
    Logger.log("Matched: " + m[1]);
}

/°([^°]*)/g是 regex文字表示法(请注意不要在其周围加上引号)，其中/是regex分隔符，°([^°]*)是与°符号匹配的模式，然后将任意数量(g)以外的0个或多个除°(([^°]*))以外的字符捕获到组1中.

The /°([^°]*)/g is a regex literal notation (mind there should be no quotes around it), where / are regex delimiters, °([^°]*) is the pattern matching ° symbol and then capturing into Group 1 any 0 or more chars other than ° (([^°]*)) any number of times (g).

要真正匹配所有出现的事件，您需要多次调用RegExp#exec并获取组1值(m[1]).

To actually match all the occurrences, you need to call RegExp#exec multiple times and grab Group 1 value (m[1]).
