选择某些 <tr> 用JSoup标记

Question

I am new to JSoup and have been working with it for a few days now with no problems, until I came across this one. I'm trying to get all the <tr> tags from a table where the <tr> s have a child <td> tag with a certain class.

I am trying to retrieve the data from this website , this is what I'm trying:

document.select("#partedenieve tr:has(td.zonas)");

I don't know if it works because the problem here is that if you select just #partedenieve tr it only returns the <tr> s on the thead . I've tried some other queries, but when I finally achieve to get <tr> s from the tbody it won't return all the <tr> tags either.

I don't know if this problem may be related to the rowspan tag present on the <tr> s I want to get... but I've had no luck so far.

Thanks in advance for your replies.

Answer 1

Try:

Elements elts = document.select("tr > td.class");

This will return all td elements with the given class. So you just have to get each unique parent:

List<Element> list = new ArrayList<Element>();
for (Element elt : elts) {
    if (!list.contains(elt) {
        list.add(elt);
    }
}

Now, your list object contains all of your tr elements.
