How to get a value of element with HTMLcleaner

Question

trying to get the value of the element "a "and "span ". Using HTMLCleaner.

<div class="info"> <p class="name"> <a href="http://www.zxdv.com/level/1/film/616/sr/1/">Tron</a> <span class="year">2001</span> </p> </div>

here is the code:

TagNode linkElements[] = rootNode.getElementsByName("div", true); int s=0; for (int i = 0; linkElements != null && i < linkElements.length; i++) { if (linkElements[i].getAttributes().toString().equals("{class=info}")) { TagNode linkElements2[] = linkElements[i].getElementsByName("p", true); for (int i2 = 0; linkElements2 != null && i2 < linkElements2.length; i2++) { TagNode linkElements3[] = linkElements2[i2].getElementsByName("a", true); TagNode linkElements4[] = linkElements2[i2].getElementsByName("span", true); for (int i3 = 0; linkElements3 != null && i3 < linkElements3.length; i3++) { if (s <= 20) { String currentlink = linkElements3[i3].getText().toString(); String currentlink2 = linkElements4[i3].getText().toString(); slink[s] = currentlink+"\n"+currentlink2; s++; } } } } }

as i understand a take first "div" element then then his child element "p", but when i taling "a" and "span" elements values return emptyю prompt please where I make mistake. thanks

Reduce work by using XPath instead

TagNode root = htmlCleaner.clean(url); // Xpath to 'a' Object[] foundList = root.evaluateXPath("//div/p[@class='name']/a"); if(foundList == null || foundList.length < 1) { return; } TagNode aNode = (TagNode)foundList[0]; String aNodeTextContent = aNode.getText(); // Xpath to 'span' foundList = root.evaluateXPath("//div/p[@class='name']/span"); if(foundList == null || foundList.length < 1) { return; } TagNode spanNode = (TagNode)foundList[0]; String spanNodeTextContent = spanNode.getText();
