How to parse HTML text and links with java and jsoup
Question
I need to parse text from a webpage. The text is presented in this way:
nonClickableText= link1 link2 nonClickableText2= link1 link2
I want to be able to convert all to a string in java. The non clickable text should remain like it is while the clickable text should be replaced with its actual link.
So in java I would have this:
String parsedHTML = "nonClickableText= example.com example.com nonClickableText2= example3.com example4.com";

What exactly is link1 and link2 ? According to your example
"... nonClickableText2= example3.com example4.com"
they can be different, so what would be the source besides the href ?
Based on you images the following code should give you everything to adopt your final string presentation. First we grab the <strong> -block and then go through the child nodes, using <a> -children with preceding text-nodes:
String htmlString = "<html><div><p><strong>\"notClickable1\"<a rel=\"nofollow\" target=\"_blank\" href=\"example1.com\">clickable</a>\"notClickable2\"<a rel=\"nofollow\" target=\"_blank\" href=\"example2.com\">clickable</a>\"notClickable3\"<a rel=\"nofollow\" target=\"_blank\" href=\"example3.com\">clickable</a></strong></p></div></html>";
Document doc = Jsoup.parse(htmlString); //can be replaced with Jsoup.connect("yourUrl").get();
String parsedHTML = "";
Element container = doc.select("div>p>strong").first();
for (Node node : container.childNodes()) {
if(node.nodeName().equals("a") && node.previousSibling().nodeName().equals("#text")){
parsedHTML += node.previousSibling().toString().replaceAll("\"", "");
parsedHTML += "= " + node.attr("href").toString() + " ";
}
}
parsedHTML.trim();
System.out.println(parsedHTML);
Output:
notClickable1= example1.com notClickable2= example2.com notClickable3= example3.com
