Hi, xpath is missing some basic functions like not, contains, etc.
It would be great if we are able to execute the following code:

    String html = "<!DOCTYPE HTML><html><body><div class=\"bb ccc\">from: <b>20</b></div><div/></body></html>";
    for (String xpath : Arrays.asList(
                    "//div[not(@class)]",
                    "//div[contains(@class,'bb')]",
                    "//div[contains(text(),'from:')]/b/text()",
                    "/html/body/div[last()-1]")) {

        CleanerProperties props = new CleanerProperties();
        props.setOmitDoctypeDeclaration(true);
        TagNode tagNode = new HtmlCleaner(props).clean(html);
        Object[] res = tagNode.evaluateXPath(xpath);
        assert (res.length > 0);
    }

Regards
R.
