Martin Barrs updated LANG-898:
------------------------------

    Description: 
{noformat} 
In an escaped XML string with escaped whitespace, in this case linefeed ( 
 
), escapexml and unescapexml treat the linefeed inconsistently. 

unescape converts 
 to a linefeed, yet escapexml does not convert linefeed 
back to 


I've put spaces between the & and # and 10 in this bug as Jira will interpret 
it: 
& # 10;

Here's code and output...


public static void main(String[] args) {
        String escaped =
                "<?xml version="1.0" 
encoding="iso-8859-1"?>
<?xml version="1.0" 
encoding="iso-8859-1"?>";

        System.out.println(escaped);
        System.out.println();
        System.out.println(StringEscapeUtils.unescapeXml(escaped));
        System.out.println();
        System.out.println(StringEscapeUtils.escapeXml(StringEscapeUtils
                .unescapeXml(escaped)));

    }
    

Output:

<?xml version="1.0" 
encoding="iso-8859-1"?>
<?xml version="1.0" 
encoding="iso-8859-1"?>

<?xml version="1.0" encoding="iso-8859-1"?>
<?xml version="1.0" encoding="iso-8859-1"?>

&lt;?xml version=&quot;1.0&quot; encoding=&quot;iso-8859-1&quot;?&gt;
&lt;?xml version=&quot;1.0&quot; encoding=&quot;iso-8859-1&quot;?&gt;

        System.out.println();
        System.out.println(StringEscapeUtils.escapeXml(StringEscapeUtils
                .unescapeXml(escaped)));

    }
