I would try to replace everything inside this string :
[JGMORGAN - BANK2] n° 10 NEWYORK, n° 222 CAEN, MONTELLIER, VANNES / TARARTA TIs
1303222074, 1403281851 & 1307239335 et Cloture TIs 1403277567,
1410315029
Except the following numbers :
1303222074
1403281851
1307239335
1403277567
1410315029
I have built a REGEX to match them :
1[0-9]{9}
But I have not figured it out to do the opposite that is everything except all matches ...
google spreadsheet use the Re2 regex engine and doesn't support many usefull features that can help you to do that. So a basic workaround can help you:
match what you want to preserve first and capture it:
pattern: [0-9]*(?:[0-9]{0,9}[^0-9]+)*(?:([0-9]{9,})|[0-9]*\z)
replacement: $1 (with a space after)
demo
So probably something like this:
=TRIM(REGEXREPLACE("[JGMORGAN - BANK2] n° 10 NEWYORK, n° 222 CAEN, MONTELLIER, VANNES / TARARTA TIs 1303222074, 1403281851 & 1307239335 et Cloture TIs 1403277567, 1410315029"; "[0-9]*(?:[0-9]{0,9}[^0-9]+)*(?:([0-9]{9,})|[0-9]*\z)"; "$1 "))
You can also do this with dynamic native functions:
=REGEXEXTRACT(A1,rept("(\d{10}).*",counta(split(regexreplace(A1,"\d{10}","#"),"#"))-1))
basically it is first split by the desired string, to figure out how many occurrences there are of it, then repeats the regex to dynamically create that number of capture groups, thus leaving you in the end with only those values.
First of all thank you Casimir for your help. It gave me an idea that will not be possible with a built-in functions and strong regex lol.
I found out that I can make a homemade function for my own purposes (yes I'm not very "up to date").
It's not very well coded and it returns doublons. But rather than fixing it properly, I use the built in UNIQUE() function on top of if to get rid of them; it's ugly and I'm lazy but it does the job, that is, a list of all matches of on specific regex (which is: 1[0-9]{9}). Here it is:
function ti_extract(input) {
var tab_tis = new Array();
var tab_strings = new Array();
tab_tis.push(input.match(/1[0-9]{9}/)); // get the TI and insert in tab_tis
var string_modif = input.replace(tab_tis[0], " "); // modify source string (remove everything except the TI)
tab_strings.push(string_modif); // insert this new string in the table
var v = 0;
var patt = new RegExp(/1[0-9]{9}/);
var fin = patt.test(tab_strings[v]);
var first_string = tab_strings[v];
do {
first_string = tab_strings[v]; // string 0, or the string with the first removed TI
tab_tis.push(first_string.match(/1[0-9]{9}/)); // analyze the string and get the new TI to put it in the table
var string_modif2 = first_string.replace(tab_tis[v], " "); // modify the string again to remove the new TI from the old string
tab_strings.push(string_modif2);
v += 1;
}
while(v < 15)
return tab_tis;
}

I am trying to get data after a colon.
This is my code:
function myFunction() {
var withBreaks = "*Cats are:* cool Pets [CATS]"
var sheet = SpreadsheetApp.getActiveSheet()
if (withBreaks) {
var tmp;
tmp = withBreaks.match(/^[\*]Cats are:[\*][\s]([a-z]+[\s]+[A-Za-z].*)$/m); //
var username = (tmp && tmp[1]) ? tmp[1].trim() : 'No username';
sheet.appendRow([username])
}
};
So I'm trying to get information after the
*Cats are:*. This code works, but, sometimes some sentences would have an asterisk and sometimes there wouldn't be an asterisk to different sentences. I would like to make one that is more unifying, if that clarifies my question a bit.
What I would like to do is, without specifying the asterisk, get data after the :. So anything after Cats are:. Do I have to specify the asterisk?
I suggest
/^\**Cats are:\**\s*([\s\S]*)/
Here, any text is captured into Group 1 with ([\s\S]*) and the asterisks are made optional with * quantifier meaning 0 or more repetitions.
See the regex demo
If the asterisks can appear 1 or 0 times, replace * with ?:
/^\*?Cats are:\*?\s*([\s\S]*)/
^ ^
See another regex demo.
P.S: --> I know there is an easy solution to my needs, and I can do it that way but, -- I am looking for a "diff" solution for learning sake & challenge sake. So, this is just to solve an algorithm in a lesser traditional way.
I am working on solving an algorithm, and thought I had everything working well but one use case is failing. That is because I am building a regexp dynamically - now, my issue is this.
I need to match letters sequentially up until one doesn't match, then I just "match" what did match sequentially.
so... lets say I was matching this:
"zaazizz"
with this: /\bz[a]?[z]?/
"zizzi".match(/\bz[z]?[i]?/)
currently, that is matching with a : [zi], but the match should only be [z]
zzi only matches "z" from the front of "zizzi", in that order zzi - I now I am using [z]? etc... so it is optional.. but what I really need is match sequentially.. I'd only get "zi" IF from the front, it matched: zzi per my regex.... so, some sort of lookahead or ?. I tried ?= and != no luck.
I still think a non-regex-approach is best here. Have a look at the following JS-Code:
var match = "abcdef";
var input = "abcxdef";
var mArray = match.split("");
var inArray = input.split("");
var max = Math.min(mArray.length, inArray.length) - 1;
for (var i = 0; i < max; i++) {
if (mArray[i] != inArray[i]) { break; }
}
input.substring(0, i);
Where match is the string to be partially matched, input is the input and input.substring(0, i) is the result of the matching part. And you can change match as often as you like.
How can I locate all positions of some word in text in one call using regular expressions in actionscript.
In example, I have this regular expression:
var wordsRegExp:RegExp = /[^a-zA-Z0-9]?(include|exclude)[^a-zA-Z0-9]?/g;
and it finds words "include" and "exclude" in text.
I am using
var match:Array;
match = wordsRegExp.exec(text)
to locate the words, but it finds first one first. I need to find all words "include" and "exclude" and there position so i do this:
var res:Array = new Array();
var match:Array;
while (match = wordsRegExp.exec(text)) {
res[res.length]=match;
}
And this does the trick, BUT very very slow for large amount of text. I was searching for some other method and didn't find it.
Please help and thanks in advance.
EDIT: I tried var arr:Array = text.match(wordsRegExp);
it finds all words, but not there positions in string
I think that's the nature of the beast. I don't know what you mean with "large amount of text", but if you want better performance, you should write your own parsing function. This shouldn't be that complicated, as your search expression is fairly simple.
I've never compared the performance of the String search functions and RegExp, because I thought there are based on the same implementation. If String.match() is faster, then you should try String.search(). With the index you could compute the substring for the next search iteration.
Found this on the help.adobe.com site,...
"Methods for using regular expressions with strings: The exec() method"
… The array also includes an index property, indicating the index position of the start of the substring match …
var pattern:RegExp = /\w*sh\w*/gi;
var str:String = "She sells seashells by the seashore";
var result:Array = pattern.exec(str);
while (result != null)
{
trace(result.index, "\t", pattern.lastIndex, "\t", result);
result = pattern.exec(str);
}
//output:
// 0 3 She
// 10 19 seashells
// 27 35 seashore
I have a list of several phrases in the following format
thisIsAnExampleSentance
hereIsAnotherExampleWithMoreWordsInIt
and I'm trying to end up with
This Is An Example Sentance
Here Is Another Example With More Words In It
Each phrase has the white space condensed and the first letter is forced to lowercase.
Can I use regex to add a space before each A-Z and have the first letter of the phrase be capitalized?
I thought of doing something like
([a-z]+)([A-Z])([a-z]+)([A-Z])([a-z]+) // etc
$1 $2$3 $4$5 // etc
but on 50 records of varying length, my idea is a poor solution. Is there a way to regex in a way that will be more dynamic? Thanks
A Java fragment I use looks like this (now revised):
result = source.replaceAll("(?<=^|[a-z])([A-Z])|([A-Z])(?=[a-z])", " $1$2");
result = result.substring(0, 1).toUpperCase() + result.substring(1);
This, by the way, converts the string givenProductUPCSymbol into Given Product UPC Symbol - make sure this is fine with the way you use this type of thing
Finally, a single line version could be:
result = source.substring(0, 1).toUpperCase() + source(1).replaceAll("(?<=^|[a-z])([A-Z])|([A-Z])(?=[a-z])", " $1$2");
Also, in an Example similar to one given in the question comments, the string hiMyNameIsBobAndIWantAPuppy will be changed to Hi My Name Is Bob And I Want A Puppy
For the space problem it's easy if your language supports zero-width-look-behind
var result = Regex.Replace(#"thisIsAnExampleSentanceHereIsAnotherExampleWithMoreWordsInIt", "(?<=[a-z])([A-Z])", " $1");
or even if it doesn't support them
var result2 = Regex.Replace(#"thisIsAnExampleSentanceHereIsAnotherExampleWithMoreWordsInIt", "([a-z])([A-Z])", "$1 $2");
I'm using C#, but the regexes should be usable in any language that support the replace using the $1...$n .
But for the lower-to-upper case you can't do it directly in Regex. You can get the first character through a regex like: ^[a-z] but you can't convet it.
For example in C# you could do
var result4 = Regex.Replace(result, "^([a-z])", m =>
{
return m.ToString().ToUpperInvariant();
});
using a match evaluator to change the input string.
You could then even fuse the two together
var result4 = Regex.Replace(#"thisIsAnExampleSentanceHereIsAnotherExampleWithMoreWordsInIt", "^([a-z])|([a-z])([A-Z])", m =>
{
if (m.Groups[1].Success)
{
return m.ToString().ToUpperInvariant();
}
else
{
return m.Groups[2].ToString() + " " + m.Groups[3].ToString();
}
});
A Perl example with unicode character support:
s/\p{Lu}/ $&/g;
s/^./\U$&/;
I am using vb.net to parse my own basic scripting language, sample below. I am a bit stuck trying to deal with the 2 separate types of nested brackets.
Assuming name = Sam
Assuming timeFormat = hh:mm:ss
Assuming time() is a function that takes a format string but
has a default value and returns a string.
Hello [[name]], the time is [[time(hh:mm:ss)]].
Result: Hello Sam, the time is 19:54:32.
The full time is [[time()]].
Result: The full time is 05/06/2011 19:54:32.
The time in the format of your choice is [[time([[timeFormat]])]].
Result: The time in the format of your choice is 19:54:32.
I could in theory change the syntax of the script completely but I would rather not. It is designed like this to enable strings without quotes because it will be included in an XML file and quotes in that context were getting messy and very prone to errors and readability issues. If this fails I could redesign using something other than quotes to mark out strings but I would rather use this method.
Preferably, unless there is some other way I am not aware of, I would like to do this using regex. I am aware that the standard regex is not really capable of this but I believe this is possible using MatchEvaluators in vb.net and some form of recursion based replacing. However I have not been able to get my head around it for the last day or so, possibly because it is hugely difficult, possibly because I am ill, or possibly because I am plain thick.
I do have the following regex for parts of it.
Detecting the parentheses: (\w*?)\((.*?)\)(?=[^\(+\)]*(\(|$))
Detecting the square brackets: \[\[(.*?)\]\](?=[^\[+\]]*(\[\[|$))
I would really appreciate some help with this as it is holding the rest of my project back at the moment. And sorry if I have babbled on too much or not put enough detail, this is my first question on here.
Here's a little sample which might help you iterate through several matches/groups/captures. I realize that I am posting C# code, but it would be easy for you to convert that into VB.Net
//these two may be passed in as parameters:
string tosearch;//the string you are searching through
string regex;//your pattern to match
//...
Match m;
CaptureCollection cc;
GroupCollection gc;
Regex r = new Regex(regex, RegexOptions.IgnoreCase);
m = r.Match(tosearch);
gc = m.Groups;
Debug.WriteLine("Number of groups found = " + gc.Count.ToString());
// Loop through each group.
for (int i = 0; i < gc.Count; i++)
{
cc = gc[i].Captures;
counter = cc.Count;
int grpnum = i + 1;
Debug.WriteLine("Scanning group: " + grpnum.ToString() );
// Print number of captures in this group.
Debug.WriteLine(" Captures count = " + counter.ToString());
if (cc.Count >= 1)
{
foreach (Capture cap in cc)
{
Debug.WriteLine(string.format(" Capture found: {0}", cap.ToString()));
}
}
}
