- You can use
attr
on anElement
object to retrieve a particular attribute's value - Use
substring
to get the required value if the String pattern is consistent
Code
// Using just your anchor html tag
String html = "<a href=\"/showship.php?mmsi=235083844\">Sunsail 4013</a>";
Document doc = Jsoup.parse(html);
// Just selecting the anchor tag, for your implementation use a generic one
Element link = doc.select("a").first();
// Get the attribute value
String url = link.attr("href");
// Check for nulls here and take the substring from '=' onwards
String id = url.substring(url.indexOf('=') + 1);
System.out.println(id + " "+ link.text());
Gives,
235083844 Sunsail 4013
Modified condition in your for
loop from your code:
...
for (Element td : tdTags) {
// Print it's text if not empty
final String text = td.text();
if (text.isEmpty() == false) {
if (td.getElementsByTag("a").first() != null) {
// Get the attribute value
String url = td.getElementsByTag("a").first().attr("href");
// Check for nulls here and take the substring from '=' onwards
String id = url.substring(url.indexOf('=') + 1);
System.out.println(id + " "+ td.text());
}
else {
System.out.println(td.text());
}
}
}
...
The above code would print the desired output.
