Question

I’d like to preface my question with an apology – which will make this into a 2 part question….double apology.
I am struggling with JSoup (again) 1st apology for repeatedly asking and not learning well enough yet – so can anyone suggest some reading beyond the usual searches for something that will help me understand how to decipher the DOM each time I try this?

If you are still inclined to help, this time, within the doc returned I have:

    <a href="/logitech-logitech-wireless-keyboard-k270-with-long-range-wireless-920-003051/info"><span id="priceProductQA1" class="productPrice">&#36;29.99</span></a>

and I want to grab the href and price “29.99”.
I’ve tried

   doc = Jsoup.connect(srchStr).get();
    for (Element choices : doc.select("a:has(.productPrice)")){
      absHref = choices.attr("abs:href"); 
      String pricetxt = choices.text();

and about 10 other ways to no avail. Any better ideas for me?

Answer 1

Here’s another solution:

for( Element element : doc.select("span.productPrice") ) // Select all 'span' tags with a 'productPrice' class and iterate over them
{
    final String price = element.text(); // save the price (= text of element)
    final String link = element.parent().absUrl("href"); // Get the 'a' tag (= parent of 'span' tag) and its absolute (!) URL

    // ... 
}

Explanation:

1. Select the span tag because you can easy decide if its the one you need (has a class, while a has none)
2. Iterate over each element from 1.
3. Get the price of the element
4. Select the parent of the span tag since it contains the required url
5. Select the absolute URL; if you want the relative one, use attr("href") instead

Btw. if you are 100% shure there’s only one of such elements on this website you can replace the for-Loop by Element element = doc.select("span.productPrice").first();, followed by the other two lines of code.
