[jira] [Commented] (LANG-890) Adding equalsIgnoreWhiteSpaces() method to StringUtils

Joerg Schaible commented on LANG-890:

However, it might make more sense to provide a method to collapse all whitespace to a single space (should probably also trim leading/trailing whitespace). Do that to both strings and then compare them.
I think that would be more generally useful than an equals method, as it would allow both case-sensitive and insensitive natching as well as potentially detecting the first difference etc.
There could also be a method to remove all whitespace.
That would ignore word-boundaries in comparisons, but would have other uses.

We have this already:

 StringUtils.normalizeSpace();
 StringUtils.deleteWhitespace();

> Currently, no java uitility package offers a method to compare two strings which differ only in format & white spaces for equality. The common scenario when we need such a method would be (a) when one needs to perform equality check between two narrative fields in a SWIFT message or (b) to compare a paragrapgh retreived from different files.
> Please advise on how i can share the code for this new method. thank you
