Question

I have a text file which contains email headers and its value. looks like below:

X-Originating-IP: [141.12.67.171]

I have noticed that in the line which starts from “From:” (with winmerge file comparing tool), there are white spaces before a newline. I would like to remove it. Actually I would like to remove all white spaces before each newline in a file. I have already gone through the posted question here : removing space before new line in java
But that did not help me unfortunately.

I would appreciate any advices to do this in java.

Answer 1

Thank you all for your responses.

Finally I could found regular expression which removes all white spaces (including non breaking white space) from a string.

str= str.replaceAll("[\\s\\u00A0]+","");
