The problem is not that the response is not valid xhtml.

The reason is that the parser that parses the response and looks for embedded
resources, does not look for constructs like <anytag
style="background:url('someurl')"/>.

I am not sure if the parser should look for such embedded resources. If the
stylesheet file references any resources, those will not be downloaded by
jmeter, because jmeter only downloads any stylesheet files referenced, it does
not parse the downloaded stylesheet files and then download all resources
referenced by the stylesheet file.

So if there should be no difference between resources mentioned inside
stylesheet files and resouces mentioned in inline style of the actual document,
then I think this bug should be closed as "invalid".

If you want resources mentioned in inline styling of the document, then the
following code could be added to the bottom of the "parseNodes" method of the
"HtmlParserHTMLParser" seems to do the work :

            String styleTagStr = tag.getAttribute("STYLE");
            if(styleTagStr != null) {
                PatternCompiler compiler = new Perl5Compiler();
                PatternMatcher matcher = new Perl5Matcher();
                Pattern pattern = null;
                PatternMatcherInput input = null;
                try {
                    pattern = compiler.compile("URL\\(('|\")(.*)('|\")\\)", 
                        Perl5Compiler.CASE_INSENSITIVE_MASK |
Perl5Compiler.SINGLELINE_MASK | Perl5Compiler.READ_ONLY_MASK);
                    input = new PatternMatcherInput(styleTagStr);
                    while (matcher.contains(input, pattern)) {
                        MatchResult match = matcher.getMatch();
                        // The value is in the second group
                        String styleUrl = match.group(2);
                        urls.addURL(styleUrl, baseUrl.url);
                    }
                } catch (MalformedPatternException mpe) {
                    log.warn("Malformed pattern for getting url of style
attribute of a tag");
                }
            }
