Regular Expression to get what’s outside of brackets

Asked

Sample text:

Itaú [123.456,89]

To get what’s inside the brackets (including the brackets) I used:

\[(.*?)\]

The question is how to get what is outside?

I imagine it’s a denied list, something simple. I’ve searched over time and nothing.

If possible, I also wanted to know how to get what is inside the bracket, without including the brackets?

All in one expression, without prolonging the code [pedaling].

Example text can be:

"Itaú 1 [123.456,89]", "Itaú 2 [543.456,59]", "Banco do Brasil [987.543,21]", etc.

That is, include accents, more than one word, so it has spaces and can occur starting with numbers.

  • Is there another example? the lines always start with a-Z0-9 followed by conchetes?

  • Example text can be "Itaú 1 [123.456,89]", "Itaú 2 [543.456,59]", "Banco do Brasil [987.543,21]", etc. That is, include accents, more than one word, so it has spaces and can occur to start with numbers.

My suggestion is to use denied classes to match "everything that is not bracket": [^\[]+ and [^\]]+.

Gathering and placing the groups was: ([^\[]+) (\[([^\]]+)\])

Example:

var str = 'Itaú 1 [123.456,89]';
var result = str.replace(/([^\[]+) (\[([^\]]+)\])/, 'grupo 1: "$1"<br>grupo 2: "$2"<br>grupo 3: "$3"<br>');
document.body.innerHTML = result;

See working on Regex.

Any clarification ask.

Pattern:

/^([^\]]+) \[([^\]]*)\]/gm

Input:

Itau [2.265,41]
Bradesco [1.375,21]
Santander Bradesco [784,12]
Caixa 2 []

Match:

MATCH 1
1.  [0-4]   `Itau`
2.  [6-14]  `2.265,41`
MATCH 2
1.  [16-24] `Bradesco`
2.  [26-34] `1.375,21`
MATCH 3
1.  [36-54] `Santander Bradesco`
2.  [56-62] `784,12`
MATCH 4
1.  [64-71] `Caixa 2`
2.  [73-73] ``

In javascript, I would do as follows:

To get only the word Itaú:

'Itaú [123.456,89]'.replace(/(\[.*\])/g, '');

To get what is inside the brackets (without the brackets):

'Itaú [123.456,89]'.match(/\[(.*)\]/)[1]

  • I’m not very good at regexp :(

  • Example text can be "Itaú 1 [123.456,89]", "Itaú 2 [543.456,59]", "Banco do Brasil [987.543,21]", etc. That is, include accents, more than one word, so it has spaces and can occur to start with numbers.

  • I think the magic of regular expressions is fantastic, but I also have a hard time finding Pattern. Due to the delay, the "ride" often appears to arrive at the solution with more lines, hehe.

$re = "/([A-Za-zÀ-ú0-9]+)([.,]?)/"; 
$str = "Itaú [123.456,89]"; 

preg_match_all($re, $str, $matches);
