Christopher Jackson created KNOX-623:
----------------------------------------
Summary: Gateway provider rewriter doesn't support boolean
attributes in HTML.
Key: KNOX-623
URL: https://issues.apache.org/jira/browse/KNOX-623
Project: Apache Knox
Issue Type: Bug
Affects Versions: 0.6.0
Reporter: Christopher Jackson
When enabling 'rewrite' on a service it fails to correctly parse HTML with
boolean attributes.
According to w3 it is valid for attributes to not have values, they are known
as boolean attributes (see link below). The current implementation of the html
filter rewriter fails to parse boolean attributes which results in those
attributes being assigned a value of null instead of remaining a boolean
attribute.

Here's an additional unit test for HtmlFilterReaderBaseTest that shows the
problem.
{code}
@Test
public void testBooleanAttribute() throws IOException,
ParserConfigurationException
{
String inputXml = "<html ng-app=\"angularapp\"
ng-controller=\"AppCtrl\" role=\"application\" aria-labelledBy=\"title\">\n" +
"<head>\n"
+ "<title id=\"title\"
ng-bind=\"pageTitle\"></title>\n" + "</head>\n" + "<body>\n" + "<div
class=\"container\">\n" + "<div ui-view></div>\n"
+ "</div>\n" + "</body>\n" + "</html>\n";
StringReader inputReader = new StringReader(inputXml);
HtmlFilterReaderBase filterReader = new
NoopXmlFilterReader(inputReader);
String outputHtml = new
String(IOUtils.toCharArray(filterReader));
assertEquals(inputXml, outputHtml);
}
{code}
