Subject [jira] [Commented] (LANG-890) Adding equalsIgnoreWhiteSpaces() method to StringUtils
Date Thu, 25 Apr 2013 10:20:16 GMT

    [ https://issues.apache.org/jira/browse/LANG-890?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13641632#comment-13641632

Sebb commented on LANG-890:
---------------------------

bq. Please advise on how i can share the code for this new method.

Not exactly sure what you mean by that, but patches (unified diff) are accepted as attachments.

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.

> 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.
