使用javascript中的regex将.split（）替换为.match（）

Question

I'm having difficulties with constructing some regular expressions using Javascript.

What I need:

I have a string like: Woman|{Man|Boy} or {Girl|Woman}|Man or Woman|Man etc. I need to split this string by '|' separator, but I don't want it to be split inside curly brackets.

Examples of strings and desired results:

// Expample 1
string: 'Woman|{Man|Boy}'
result: [0] = 'Woman', [1] = '{Man|Boy}'

// Example 2
string '{Woman|Girl}|{Man|Boy}'
result: [0] = '{Woman|Girl}', [1] = '{Man|Boy}'

I can't change "|" symbol to another inside the brackets because the given strings are the result of a recursive function. For example, the original string could be

'Nature|Computers|{{Girls|Women}|{Boys|Men}}'

Answer 1

try this:

var reg=/\|(?![^{}]+})/g;

Example results:

var a = 'Woman|{Man|Boy}';
var b = '{Woman|Girl}|{Man|Boy}';

a.split(reg)
["Woman", "{Man|Boy}"]

b.split(reg)
["{Woman|Girl}", "{Man|Boy}"]

for your another question:

"Now I have another, but a bit similar problem. I need to parse all containers from the string. Syntax of the each container is {sometrash}. The problem is that container can contain another containers, but I need to parse only "the most relative" container. mystring.match(/\\{+.+?\\}+/gi); which I use doesn't work correctly. Could you correct this regex, please? "

you can use this regex:

var reg=/\{[^{}]+\}/g;

Example results:

    var a = 'Nature|Computers|{{Girls|Women}|{Boys|Men}}';

    a.match(reg)
    ["{Girls|Women}", "{Boys|Men}"]

Answer 2

You can use

.match(/[^|]+|\{[^}]*\}/g)

to match those. However, if you have a nesting of arbitrary depth then you'll need to use a parser, [javascript] regex won't be capable of doing that.

Answer 3

测试一下：

([a-zA-Z0-9]*\|[a-zA-Z0-9]*)|{[a-zA-Z0-9]*\|[a-zA-Z0-9]*}
