Question

I’m parsing a text file and I need to remove all terms such this:

upcoming:event=103499
abc:dfe=123813
...

Format: `term1:term=0000000`

I’m currently using this reg expression to remove such terms from my text file:

   myString = myString.replaceAll("[0-9A-Za-z]+:[0-9A-Za-z]+", "");

So for example, if I have a string like this:

"blabla abc:dfe=123813 cococo ghi:pol=09339 pppoooo"

it should become: "blabla cococo pppoooo"

But it doesn’t work

thanks

You need to assign the return value of replaceAll back to the string reference:

myString = myString.replaceAll("[0-9A-Za-z]+:[0-9A-Za-z]+", "");

And it works

But if you want to replace the entire string you can do:

myString = myString.replaceAll("[0-9A-Za-z]+:[0-9A-Za-z=]+", "");

EDIT:

For the edited question you can use:

myString = myString.replaceAll("[0-9A-Za-z]+:[0-9A-Za-z]+=[0-9]+ ?", "");
