> 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.
> http://www.w3.org/html/wg/drafts/html/master/infrastructure.html#boolean-attributes
> 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}
