I need a regular expression to parse out the companyid and branchid in a url. The issue is that the branchid may occur at the end of the string or it may occur in the middle of the string. it will always follow /branches. Here are 2 examples:

I’m trying to build a regular expression to return initial value and then all key value pairs.

I’m trying to write a simple localized URL detection module, I’m using https://regexr.com/ to test my message as below

I have a text line matching this pattern d{2}s?[a-zA-Z]s?d{2,5} zero to many times.

I am working on multi-replacement tool and need to replace name of OBJECT_TYPE to different variants.

I am trying to match a multi line text using Java. When I use the Pattern class with the Pattern.MULTILINE modifier, I am able to match, but I am not able to do so with (?m).

Why is this with Patter.MULTILINE set not matching?

My regex (ddX) should match two digits followed by a specific character ‘X’. Any number of optional characters are allowed to precede it provided it ends with a + character.
For Example:
12X is valid
ABC+22X is valid
ABC+123X is not valid.
I came up with the following regex But this does not work as expected.

In this Remove consecutive duplicate words, we would take
"alpha beta beta gamma gamma gamma delta alpha beta beta gamma gamma gamma delta"
as a input string, and output.
"alpha beta gamma delta alpha beta gamma delta"
One of the solution I saw was. very elegant but I still struggle with the regex

String orig=”abc”; System.out.println (orig.matches (“abc”)); // true System.out.println (orig.matches (“^abc$”)); // true System.out.println (orig.matches (“^\a\b\c$”)); // false Why is the last match with escaped chars false? Is it not allowed to escape EVERY character? java regex
