How to parse HTML table using jsoup?

Yes, it is possible with JSoup. First, you select the table. Then, you select the <tr> tags for rows. You can start from the second index since the first row contains only the column names. Then loop over the <th> tags and get the specific index. In your case, the indexes 7 and 5 are important(index 7: Status, index 5: Host Name). Check the status if it equals to down and if it is, then add the Host Name to a list. That’s all.

ArrayList<String> downServers = new ArrayList<>();
Element table = doc.select("table").get(0); //select the first table.
Elements rows = table.select("tr");

for (int i = 1; i < rows.size(); i++) { //first row is the col names so skip it.
    Element row = rows.get(i);
    Elements cols = row.select("td");

    if (cols.get(7).text().equals("down")) {
        downServers.add(cols.get(5).text());
    }
}

Update:
When you find the word Titan you can create another loop and look if the cluster name is empty.

Edit: I change the while loop to do while loop.

    ArrayList<String> downServers = new ArrayList<>();
    Element table = doc.select("table").get(0); //select the first table.
    Elements rows = table.select("tr");

    for (int i = 1; i < rows.size(); i++) { //first row is the col names so skip it.
        Element row = rows.get(i);
        Elements cols = row.select("td");

        if (cols.get(3).text().equals("Titan")) {
            if (cols.get(7).text().equals("down"))
                downServers.add(cols.get(5).text());

            do {
                if(i < rows.size() - 1)
                   i++;
                row = rows.get(i);
                cols = row.select("td");
                if (cols.get(7).text().equals("down") && cols.get(3).text().equals("")) {
                    downServers.add(cols.get(5).text());
                }
                if(i == rows.size() - 1)
                    break;
            }
            while (cols.get(3).text().equals(""));
            i--; //if there is two Titan names consecutively.
        }
    }

downServers ArrayList will contain the list of down servers hostnames.
