How to apply ads blocker to HTML content get by Java HttpClient GET request and parse by Jsoup?

I am going to crawl newspaper, article. However I don't want ads. I want to apply ads block on top of my request (similar to browsing the web manually with ads block on, then save the HTML page without ads)

DefaultProxyRoutePlanner routePlanner = new DefaultProxyRoutePlanner(proxy);
CloseableHttpClient httpClient = HttpClientBuilder.create()
   .setDefaultRequestConfig(this.config)
   .setRoutePlanner(routePlanner)
   .setSSLContext(sslContext)
   .setConnectionManager(cm)
   .setConnectionManagerShared(true)
   .build();

HttpGet getRequest = new HttpGet(url);
getRequest.setHeader("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.95 Safari/537.11");
                    try (CloseableHttpResponse response = httpClient.execute(getRequest)) {
                        String headerContentType = response.getFirstHeader("Content-Type").getValue();
                        if (headerContentType != null && headerContentType.contains("text/html")) {
                            HttpEntity entity = response.getEntity();
                            if (entity != null) {
                                content = EntityUtils.toString(entity, "utf-8");
                                EntityUtils.consume(entity);
                            }
                        } else {
                            // log fail event here
                        }
                    }

Now I have String content as HTML content.
I parse the content with org.jsoup.Jsoup.

    Document contentDoc = Jsoup.parse(
            content
    );
    String contentstr = contentDoc.body()
            .getElementsByTag("p")
            .text();
