</tr>

and I need to get url from element with red color:

<p align="center"><font size="1" color=red> 16 </font></td>

I decided to use jsoup library, and here what I try to do:

Document document = Jsoup.connect(siteUrl).execute().parse();

Element table = document.select("table").get(2);
Elements links = table.getElementsByTag("a");
String date = table.select("*[color*='red']").first().toString();
System.out.println("Date: " + date);
for (Element link: links) {
    String url = link.attr("href");
    String text = link.text();

    System.out.println(text + ", " + url);
}

But in such way I just can get this element and all links. And I think that to get list of all urls and find needed using "date" is not the smartest thing. So could someone please advice, how I can cope with this task?

Answer 1

I'm assuming the HTML in the example is a typo since it is malformed (ie closing tags missing for a and p tags).

If the HTML was valid, the following code would get the url you want after selecting the table element:

Element redElement = table.select("*[color*='red']").first();

// Get the sibling (a tag) of its parent (p tag) and get the value of href.
String url = redElement.parent().previousElementSibling().attr("href");
System.out.println("URL: " + url);
