如何使用嵌入式双引号解析字符串 [英] How to Parse a string with Embedded Double Quotes

问题描述

我有一个类似于以下内容的字符串：


" MyString 40Hello world所有


它包含空格，可能是空格或制表符，或者是一个组合，我想要生成一个包含以下元素的数组


arr（0）=" MyString"

arr（1）= 40

arr（2）=" Hello world"

arr（3）=" all"


使用修剪和正则表达式（\s +），我可以将我的字符串减少到


" MyString 40" Hello world"所有


和Split我可以得到


arr（0）=" MyString"

arr （1）= 40

arr（2）="" Hello"

arr（3）=" world""

arr（4）=" all"


正如你所看到的，它不是我需要的。 Hello world

中的空格已减少到单个空格，而Split不会尊重双重
引号，并将Hello world分割为Hello world。超过两个元素。


有谁知道我该怎么做？我可以按字符处理字符串

，但是我希望有一个直接的

技术来做，没有循环，并使用一些技术我已经拥有
了。


TIA

I have a string similar to the following:

" MyString 40 "Hello world" all "

It contains white space that may be spaces or tabs, or a combination, and I
want to produce an array with the following elements

arr(0) = "MyString"
arr(1) = 40
arr(2) = "Hello world"
arr(3) = "all"

Using trim and a regular expression ("\s+"), I can reduce my string to

"MyString 40 "Hello world" all"

and with Split I can get

arr(0) = "MyString"
arr(1) = 40
arr(2) = ""Hello"
arr(3) = "world""
arr(4) = "all"

As you can see, it is not quite what I need. The spaces in "Hello world"
have been reduced to a single space, and Split does not respect the double
quotes, and splits "Hello world" over two elements.

Does anyone have an idea how I could do this? I could process the string
character by character, but I am hoping that there is a straight-forward
technique for doing it, without looping, and using some of the techniques I
already have.

TIA

Charles

推荐答案

Charles，


我正在看问题，我想我会给出答案，因为

它是如此难以形容。比我看到那是你。因此它不应该是一个问题。


在这种情况下我更换我不会用的空间

绝对未使用的角色。


拆分


然后再将未使用的角色替换为空间


我认为这对你来说是足够的解释。


现在你读了这个你说的，我也知道。

Charles,

I was looking at the problem, I was thinking will I give my answer because
it is so difficult to describe. Than I saw that it was you. Therefore it
should not be a problem.

In this kind of situations I replace the spaces I will not use for an
absolute unused character.

Do the split

And replace the unused character again back for a space

I assume that this is for you more than enough explanation.

And now you read this you say, I knew that as well.

Hi Cor

你读了我的想法;-)


我曾想过使用类似＃的东西，因为它永远不会出现在我的

字符串中。但后来我开始研究如何知道哪些空格要用＃替换为
，哪些空格要离开。当然，对于人眼而言，显而易见的是，我只能替换人与人之间的空间。和，但现在我回到

逐字符处理字符串的每个部分，以便我正确地匹配

双引号，这就是我在尝试要避免。


也许有一个匹配双引号的正则表达式，或者一个解析字符串的

方法，但遗憾的是我不要

知道它。


但请保持建议流畅。

Hi Cor

You read my mind ;-)

I had thought of using something like #, as it will never occur in my
string. But then I started to look at how I would know which spaces to
replace with #, and which to leave. Of course, to the human eye it is
obvious that I only replace the spaces between " and ", but now I am back to
processing each part of the string character by character so that I match
double quotes correctly, and this is what I was trying to avoid.

Perhaps there is a regex expression that will match double quotes, or a
method that parses a string taking these into account, but sadly I do not
know it yet.

But please, keep the suggestions flowing.

Charles，

在这种情况下，我会替换我不会用于
绝对未使用的字符的空格。
做分裂

然后再将未使用的角色替换回来以获得空间

我认为这对你来说已经足够了解。
