I am building a search functionality and I am trying to make it similar to the one in Sublime Text.
Assume "cmd" as the input string and "command" is one of the results.
To search the files, among other things, I split that input by chars and end up with the following regex: c.*?m.*?d. This part is succesfull in finding files like "command", however, when I use the same regex to replace the found string with some HTML elements to evidentiate the fact that the searched string is found in that particular item, this results in something like this:
<span>command</span>
I understand exactly why this is happening and I'm looking for and alternative to display to the user something like the following:
<span>c</span>o<span>m</span><span>m</span>an<span>d</span>
Or, maybe just:
<span>c</span>o<span>m</span>man<span>d</span>
I have an idea of how to do this, which is by encapsulating every single character in between parantheses and then replace every single one with the <span>$x</span> part, but I'm not sure how to do this exactly.
Any kind of help is immensely appreciated.
Thanks,

At the moment, I have a PHP function that gets the contents of a CSV file and puts it into a multi-dimensional array, which contains text that I print out in various places, using the indexes.
an example of use would be:
$localText[index][pageText][conceptQualityText][$lang];
The first index, [index], would be the name of the page. The second index [pageText] would indicate what it is (text for the page). The third index, [conceptQualityText] indicates what the actual text is. The last index, [$lang] gets the text in the desired language.
so:
->page location
->what is it
->the content
->what language it should be displayed in.
This all worked fine in the previous PHP versions. However, upgrading to 7.2, PHP seems to be a bit more strict. I was a bit more green ~2 years ago when I first made this solution, and now know that since these indexes aren't defined as strings e.g. encapsulated in single quotes like so: ['index'], they fit the notation of a superglobal (DEFINE). I didn't give it much thought back then, but now PHP seems to interpret them as so (superglobals), and so I get thrown the error that x word is an undefined superglobal.
My initial thought is to make a search and replace on my example string:
$localText[index][pageText][conceptQualityText][$lang];
using the regular expression functionality in Notepad++.
However, the example is just one of many, the notation of the array indexing is basically:
$localText[index][index2][index3][$lang];
So my question is:
How can I make use of the Notepad++ search and replace, using a regular expression, so that my index pointers become strings, instead of acting as superglobal variables?
e.g. make:
$localText[index][index2][index3][$lang];
into:
$localText['index']['index2']['index3'][$lang];
I will need some sort of logic that checks for whatever is inside the brackets and encapsulates them with single quotes, except for the last index, [$lang].
I tried to give as much information as possible, let me know if anything needs to be elaborated.
I tried to refer to these docs without much luck.
I found a solution using
this:
find: \b(localText\[)([a-zA-z0-9_\-]+)(\]\[)([a-zA-z0-9_\-]+)(\]\[)([a-zA-z0-9_\-]+)
replace: $1'$2'$3'$4'$5'$6'
and it works like a charm. Thanks for everyone who took their time to help.
You can use the following regex to match:
\[[^'](\w+)[^']\]
The regex matches a Word between Square brackets unless it quoted.
Replace with:
['$1']
The regex will not match the last brackets because it contains a '$' sign.
I'm struggling to find the right regular expression and after following the answers in other threads don't think this is a duplicate as they didn't solve my specific issue.
I have lots of files and assuming one of them contains text that looks like this:
createdby:me
one of these words should match
Would like to be able to retrieve it by matching to, for example, createdby:me and one.
The closest I've been able to get from a previous example was to use a regular expression like this.
(createdby:me|one)
This does return the file, but it also returns any other files which contain either of the terms—I'd like to return only files with both.
Is there a way to match similarly for and instead of or?
The order isn't important as the createdby:me will always proceed the search term.
Nor do I need to capture the matches.
Try this:
(?:createdby:me[\w\W]*one)|(?:one[\w\W]*createdby:me)
Hi i have a long list of items (~6k), that comes in this format:
'Entry': ['Entry'],
What i want to do, is if within the first bracket, the words match, i.e.:
'ACT': ['KOSOV'],
'ACT': ['STIG'],
I want it to leave only one of the entries, it doesn't matter which entry the first the second or whatever, i just need it to leave one of them.
If possible I would like to accomplish that by sublime, or notepad++ using regexp and if there is no way then do whatever you think is best to solve this.
UPD: The AWK command did the job indeed, thank you
You can't solve this using just regular expressions. You either need to remember all entries you've seen so far while scanning the text (would require writing a small utility program, probably), or you could sort the entries and then remove any repeated entries.
If you have a sorted file, then you can solve it using a regular expression, such as this one:
^(([^:]+):.+\n)(?:\2.+\n)+
Replace with \1. See it in action here
Hi I have a Stylesheet where i use xsl:analyze-string with the following regex:
(&journal_abbrevs;)[\s ]*([0-9]{{4}})[,][\s ][S]?[\.]?[\s ]?([0-9]{{1,4}})([\s ][(][0-9]{{1,4}}[)])?
You don't need to look at the whole thing :)
&journal_abbrevs; looks like this:
"example-String1|example-String2|example-String3|..."
What I need to do know is exclude one of the strings in &journal_abbrevs; from this regex. E.g. I don't want example-String1 to be matched.
Any ideas on how to do that ?
It seems XSLT regex does not support look-around. So I don't think you'll be able to get a solution for this that does not involve writing out all strings from journal_abbrevs in your regex. Related question.
To minimize the amount of writing out, you could split journal_abbrevs into say journal_abbrevs1, journal_abbrevs2 and journal_abbrevs3 (or how many you decide to use) and only write out whichever one that contains the string you wish to exclude. If journal_abbrevs1 contains the string, you'd then end up with something like:
((&journal_abbrevs2;)|(&journal_abbrevs3;)|example-String2|example-String3|...)...
If it supported look-around, you could've used a very simple:
(?!example-String1)(&journal_abbrevs;)...
Let presume we have something like this:
<div1>
<h1>text1</h1>
<h1>text2</h1>
</div1>
<div2>
<h1>text3</h1>
</div2>
Using RegExp we need to get text1 and text2 but not text3.
How to do this?
Thanks in advance.
EDIT:
This is just an example.
The text I'm parsing could be just plain text.
The main thing I want to accomplish is list all strings from a specific section of a document.
I gave this HTML code for example as it perfectly resembles the thing I need to get.
(?siU)<h1>(.*)</h1> would parse all three strings, but how to get only first two?
EDIT2:
Here is another rather dumb example. :)
Section1
This is a "very" nice sentence.
It has "just" a few words.
Section2
This is "only" an example.
The End
I need quoted words from first but not from second section.
Yet again, (?siU)"(.*)" returns quoted words from whole text,
and I need only those between words Section1 and Section2.
This is for the "Rainmeter" application, which apparently uses Perl regex syntax.
I'm sorry, but I can't explain it better. :)
For the general case of the two examples provided -- for use in Rainmeter regex -- you can use:
(?siU)<h1>(.*)</h1>(?=.+<div2>) for the first sample and
(?siU)"(.*)"(?=.+Section2) for the second.
Note that Rainmeter seems to escape things for you, but you might need to change " to \", above.
These both use Positive Lookahead but beware: both solutions will fail in the case of nested tags/structures or if there are mutiple Section1's and Section2's. Regex is not the best tool for this kind of parsing.
But maybe this is good enough for your current needs?
Use a DOM library and getElementsByTagName('div') and you'll get a nodeList back. You can reference the first item with ->item(0) and then getElementsByTagName('h1') using the div as a context node, grab the text with ->nodeValue property.
