Wrong behavior of Entities.unescape
-----------------------------------
Key: LANG-313
URL: https://issues.apache.org/jira/browse/LANG-313
Project: Commons Lang
Issue Type: Bug
Affects Versions: 2.2, 2.1
Reporter: Thiago Souza
Fix For: 2.3
Hi,
There's seems to be a bug at Entities.unescape. Try for example
StringEscapeUtils.unescapeHtml("& &"). It outputs "& &" instead of "&
&". The problem is at this piece of code:
if (entityValue == -1) {
buf.append('&');
buf.append(entityName);
buf.append(';');
} else {
buf.append((char) (entityValue));
}
i = semi;
The method always skips to the next ";", even if it doesn't finds the
entity value and then disregarding any entity that may be actually be referred
inside.
Regards,
Thiago Souza
