Jsoup - getting a HTML tag with ONLY the specified attributes and its values

Question

I want to use jsoup to extract elements from a page that have only some specific attributes and values. I have gone through the below mentioned methods and none solved my purpose well:

1. Jsoup's getElementsByAttributesMatching

2. This format of select query:

    doc.select("table[width=100%]").select("table[cellpadding=0]").select("table[cellspacing=0]"); 

3. This one too:

    doc.select("table[width=100%][cellpadding=0][cellspacing=0]"); 

When I use these methods I am getting elements which have the attributes I have mentioned plus other attributes too. What I want are the elements with ONLY the specified attributes.

Is there a way to get pass this huddle?

Answer 1

Your selector already select element having a specific value for those 3 attributes. So the element has at least 3 attributes. But if it has exactly 3 attributes, then those are the ones you specified.

for (Element el: doc.select("table[width=100%][cellpadding=0][cellspacing=0]"))
    if (el.attributes().size() == 3)
        // Do something

Example

Document doc = Jsoup.parse(
    "<table width=100% cellpadding=0 cellspacing=0>OK</table>" +
    "<table width=100% cellpadding=0 cellspacing=0 height=100%>NO</table>");

for (Element el: doc.select("table[width=100%][cellpadding=0][cellspacing=0]"))
    if (el.attributes().size() == 3)
        System.out.println(el.text());

Output

OK
