android html download and parse error

Question

I am trying to download the html file using the ul of the page. I am using Jsoup. This is my code:

TextView ptext = (TextView) findViewById(R.id.pagetext);
    Document doc = null;
    try {
         doc = (Document) Jsoup.connect(mNewLinkUrl).get();
    } catch (IOException e) {
        Log.d(TAG, e.toString());
        e.printStackTrace();
    }
    NodeList nl = doc.getElementsByTagName("meta");
    Element meta = (Element) nl.item(0); 
    String title = meta.attr("title"); 
    ptext.append("\n" + mNewLinkUrl);

When running it, I am getting an error saying attr is not defined for the type element. What have I done wrong? Pardon me if this seems trivial.

Answer 1

Ensure that Element refers to org.jsoup.nodes.Element, not something else. Verify your imports. Also ensure that Document refers to org.jsoup.nodes.Document. It does namely not have a getElementsByTagName() method. Jsoup doesn't utilize any of the org.w3c.dom API.

Here's a complete example with the correct imports:

package com.stackoverflow.q4720189;

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;

public class Test {

    public static void main(String[] args) throws Exception {
        Document document = Jsoup.connect("http://example.com").get();
        Element firstMeta = document.select("meta").first();
        String title = firstMeta.attr("title"); 
        // ...
    }

}

Answer 2

As I understand, Element here is org.w3c.dom.Element. Then use meta.getAttribute() instead of attr. Element class simply doesn't have such method.
