Question

I’m in great trouble.

I must check if a string fits (matches) another string with RegEx.
For example, given the following string:

Apr 2 13:42:32 sandbox izxp[12000]: Received disconnect from 10.11.106.14: 10: disconnected by user

In the editable input field I give the program the following shortened string:

Received disconnect from 10.11.106.14: 10

If it fits the existing string (as you can see above), it is OK.
If any part of the new edited string doesn’t fit the original string, I must warn the user with a message.

Could you help me solving this question with RegEx? Or another method?
I would appreciate it!

Answer 1

You must get the original string in a variable, let’s call it $original (this is perl). Then you must get the input from the “editable input field”, let’s call it $input.

Then it is a simple

if ($original=~/$input/)
{
   #Your code for a message to the user here 

}
