Question

I am using the Jsoup library to read a URL. This url has text within a few

Answer 1

Yes. You can use Element#getElementsByTag() to get all the script tag . Each script tags will be represented by the DataNode.

 Document doc =Jsoup.connect("http://stackoverflow.com/questions/16780517/java-obtain-text-within-script-tag-using-jsoup").timeout(10000).get();
 Elements scriptElements = doc.getElementsByTag("script");

 for (Element element :scriptElements ){                
        for (DataNode node : element.dataNodes()) {
            System.out.println(node.getWholeData());
        }
        System.out.println("-------------------");            
  }

Answer 2

Document doc = Jsoup.parse(html);
Elements scripts = doc.getElementsByTag("script");
for (Element script : scripts) {
    System.out.println(script.data());
}

Answer 3

Alternatively, you could use the Element#html() method that returns the inner html of an element.

Since 1.11.1: Use efficient Element#selectFirst() method to find the script element.

Document doc = Jsoup.connect("http://www.example.com").timeout(10000).get();
Element scriptElement = doc.selectFirst("script");

// Don't forget to check scriptElement is not null...

String jsCode = scriptElement.html(); 

Up to Jsoup 1.10.3: Combine Element#select() and Elements#first() calls to find the script element.

Document doc = Jsoup.connect("http://www.example.com").timeout(10000).get();
Element scriptElement = doc.select("script").first();

// Don't forget to check scriptElement is not null...

String jsCode = scriptElement.html();

According to your case the solution will be as below.

Document doc = Jsoup.connect("http://www.example.com").timeout(10000).get();
Elements scripts = doc.select("script");

for (Element script : scripts) {
    String type = script.attr("type");
    if (type.contentEquals("text/javascript")) {
        String scriptData = script.data(); // your text from the script
        break;
    }
}
