Question

I have a long text which contains paths to some files.

What I want to do is to remove the paths from it.
The filepaths are all something like:

some text 1
/all/extraItems/Java/.Scripts/.Sample1.js
some text 2
/all/extraItems/Android/.Scripts/.Sample2.js
some text 3

I know that using “^/all” will select a sentence that starts with /all and also .js$ for ending with .js. But I cannot merge these together to select the whole filepath.

After all the Regular Expression should be placed on the following code to remove the Paths.

text.replaceAll(<RegularExpression> , "");

Who can I write the regEx for it? Is there any tool?

Answer 1

If you want to “merge” them you will have to match the characters in between, as well:

^/all.*?\.js$

. matches any character, * repeats the previous character 0 or more times, ? makes the repetition ungreedy, avoiding a match going over multiple lines. Since you are using Java, you need to escape the backslash once more in your string:

"^/all.*?\\.js$"

If you do not use the multiline option already (which you actually need to do, for ^/all and js$ to work on your input), you can do that like this:

"(?m)^/all.*?\\.js$"
