Android: how to search a word or a phrase with Jsoup

My problem is: how can I search a word or a phrase in the page selected with Jsoup.
For example if the word or phrase in in a span how can I find per example the text next to this <span>? For example a link?

Html example code:

   ...
  <div class="div">
  <span>my y favourite text </span>
  <a href="www.mylink.com">my link </a>
  </div>
   ....

From this example how to find that my word is favourite and I also want to retrieve the link in <a href>?

Target: get text in a span and href attribute of a sibling a element, if the span contains a specified search word.

One way is to look for a a having the href attribute set, that has a preceding sibling span element. Then select the parent element and therein the span element to compare the content. For the parsing of a DOM tree, jsoup is a good option.

Example Code

String source = "<div class=\"div\"><span>my y favourite text </span><a href=\"http://www.mylink.com\">my link </a></div>" +
        "<div class=\"div\"><span>my y favourite 2 text </span><a href=\"/some-link.html\">my link 1</a></div>" +
        "<div class=\"div\"><span>my y text </span><a href=\"http://www.mylink.com\">my link 2</a></div>";

String searchWord = "favourite";

Document doc = Jsoup.parse(source, "UTF-8");
doc.setBaseUri("http://some-source.com"); // only for absolute links in local example

Element parent;
String spanContent="";
String link = "";

for (Element el : doc.select("span ~ a[href]")) {
    parent = el.parent();
    if(parent.select("span").text().contains(searchWord)){
        spanContent = parent.select("span").first().text();
        link = parent.select("a[href]").first().absUrl("href");

        System.out.println(spanContent + " -> " + link); // do something useful with the matches
    }
}

Output

my y favourite text -> http://www.mylink.com
my y favourite 2 text -> http://some-source.com/some-link.html
