I need some help trying to select a certain part of a string with regular expression.
Here is the string.
http://site.com/bathroom.jpg&h=165&w=204&zc=1&q=90&a=c
And I need to select "&h=165&w=204&zc=1&q=90&a=c" part of it out.
Would regular expression be the best approach to this and if so, how?
Thanks...
Find the first & and take everything starting from it. The regex:
&.*
use substring like
function getSecondPart(str) {
return str.split('jpg')[1];
}
// use the function:
alert(getSecondPart("http://site.com/bathroom.jpg&h=165&w=204&zc=1&q=90&a=c"));

I need to extract one number from a Jmeter response using regular expression extractor as part of correlation.
Scenario is:
<span>Abc456ABC</span>
If I use <span>(.*?)</span>, then I will get "Abc456ABC".
If I use <span>Abc(.*?)ABC</span>, then I will get "456".
But the left and right boundary can vary.The input can be like:
Abcdef789ABCgh
I need only the number[In last case it is "789"]. Please suggest the suitable regular expression extractor.
Thanks In Advance..
<span>.*?([0-9]+).*?</span>
You can simply use this.See demo.
https://regex101.com/r/uE6jQ1/11
You can use the following:
<span>\D+(\d+)\D+</span>
See RegEX DEMO
you can use <span>([\w]+)(\d+)([\w+])</span>, It'll surely work
But use $2$ as template in regular expression extractor
([\w]+):it will capture all words and
(\d+): will take care of digits for you
I am working with regular expressions, I need to create an expression for validating strings against the following scenario:
Solution.<word1|word2|word3>.<word4|word5>.anyword.(any word containing proj in it)
I tried
Solution.\b(word1|word2|word3)\b.\b(word4|word5)\b.(.*).\b(.*proj)\b
But this allows strings like Solution.word1.word4.blabla.blabla.csproj, meaning it allows anything before the proj because of the .*.
Can someone help me with this??
Looks like you need this regex:
Solution\.(word1|word2|word3)\.(word4|word5)\.([^.]+)\..*?\bproj\b
RegEx Demo
You might want to try (need to escape the . and allow capturing group to have chars except .):
Solution\.\b(word1|word2|word3)\b\.\b(word4|word5)\b\.([^\.]*)\.\b([^\.]*proj)\b
It's hard to consider the actual strings you want to allow without more clarification.
You can try the following regular expression.
Solution\.word[123]\.word[45]\.\w+\.\w*proj\b
I have the following string 3}HFB}4AF4}1 -M}1.
I have searched for this string using the regex :
([0-9])(\})([A-Z]{3})(\})([0-9][A-Z]{2}[0-9])(\})([0-9])(\s\-)([A-Z])(\})([0-9]).
I want to replace the } with 0. The Result I am looking for is 30HFB04AF401-M01, any assistance is appriciated. The tool I am using is Regex Buddy
A possible solution
Problem solved? In JavaScript at least :-)
"3}HFB}4AF4}1 -M}1".replace(/\}/g, "0");
// "30HFB04AF401 -M01"
I'm missing the point, right?
Assuming the language is JavaScript, we can write something like
"dfghj456783}HFB}4AF4}1 -M}1fghjkl8765".replace(/(?:[\d\w\s]+)([0-9]}[A-Z]{3}}[0-9][A-Z]{2}[0-9]}[0-9] -[A-Z]}[0-9])(?:[\d\w\s]+)/g, function () {
return arguments[1].replace(/}/g, "0");
});
What's possible in other languages though may be a different story.
Try the home of RegexBuddy for details.
So you've already got an expression to find instances of the string. Now you can either use groups to replace the characters, or you can use a separate regular expression over the string you found, simply replacing the } character within group(0) (which is the entire matched part of the input). I would certainly prefer the latter.
Fred seems to have created the replacement method for you already, so I won't repeat it here.
I have managed to find a solution to the formating in the JGSoft Lanugage used by Regex Buddy, thanks to all that provided suggestions that helped me channel my thoughts in the right direction.
Solution(I am still a beginner with Regex hence the syntax might not be efficent, but it does the job!!)
Using Group Names instead of Regex assiging groups with backreference and $ syntax.
Hence to replace 0 for } in the string 3}HFB}4AF4}1 -M}1 or any similar string. I used the following search and replacement syntax
Search : (?<Gp1>([0-9]))(?:})(?<Gp2>([A-Z]){3})(?:})(?<Gp3>([0-9])([A-Z]{2})([0-9]))(?:})(?<Gp4>([0-9]))(?:\s-)(?<Gp5>([A-Z]))(?:})(?<Gp6>[0-9])
Replace : ${Gp1}0${Gp2}0${Gp3}0${Gp4}-${Gp5}0${Gp6}
Result : 30HFB04AF401-M01
I am trying to find a regular expression that will recognize files with the pattern as az.4.0.0.119.tgz. I have tried the regular expression below:
([a-z]+)[.][0-9]{0,3}[.][0-9]{0,3}[.][0-9]{0,3}[.]tgz
But, no luck. Can anyone please point me in the right direction.

Better to use a simple regex like this:
^([a-z]+)\.(?:[0-9]+\.)+tgz$
You just forgot one number part:
([a-z]+)[.][0-9]{0,3}[.][0-9]{0,3}[.][0-9]{0,3}[.][0-9]{0,3}[.]tgz
or
([a-z]+)[.]([0-9]{0,3}[.]){4}tgz
Depending on where and how you use the regex, you might want to surround it in ^...$.
Your pattern has 4 chiffers group, your regexp only 3.
What would regular expression look like for any string which ends with .txt?
Tried few myself but it doesn't look like I'm getting anywhere.
I'd like to construct a regex object to feed a function.
Something like : .*\.txt$
If you want more precisions, I guess you should precise a language and some other stuffs...
All you have to do is match the end of the string using
/\.txt$/
Matching more than that e.g., .*\.txt$ is not necessary
Assuming Perl-style regular expressions, /[^\.]*\.txt$/ should work.
