Question

I am trying to process only the elements of type <a> in a list:

int i = 0;
for (Element el : els) {
    i++;        
    Log.w(TAG, "--------------------------");
    Log.w(TAG, "el(" + i + "): " + el.html());
    if (el.tagName().contentEquals("a")) {
        Log.d(TAG, "<a> only! el(" + i + "): " + el.html());
      }
 }

But the LogCat output only shows the Log.w() ones, not the the Log.d(), although I can see clearly in the Log.w() output that there are elements of type <a>:

 --------------------------
 el(1): 
 --------------------------
 el(2): <a href="http://www.ddd.tld/article/ar01.html?mod=Header"><em>Subject1:</em> One line of text </a>
 --------------------------
 el(3): 
 --------------------------
 el(4): 
 --------------------------
 el(5): <a href="http://www.ddd.tld/article/ar02.html?mod=Header"><em>Subject Two:</em> Another line of text </a>
 --------------------------
 el(6): 
 --------------------------
 el(7): 
 --------------------------
 el(8): <img src="images/sub_key.gif" />&nbsp;<a href="http://www.ddd.tld/article/ar03.html?mod=Header"><em>Subject Three:</em> Yet another line of text </a>
 --------------------------
 el(9): 
 --------------------------
 el(10): 

What am I missing? What am I doing wrong?

Answer 1

The correct way to select all elements with an <a> tag would be to use a CSS selector. You can use this on an Elements object. To convert your List<Element> to an Elements you simply use the Elements(Element... elements) constructor like so:

Elements webPage = new Elements(els);

From this, you can use the CSS Selectors to extract the Elements like so:

Elements aTags = webPage.select("a");

You can then iterate through these and do as you wish with them.
