Retrieving information from an XML file using DOM in Java

Question

I have been struggling on this for quite a while.I'm trying to figure out how to get "Crime, Drama, and Thriller. from category any category using DOM for Java. I'm also having trouble understanding how I should dive into this. (for Instance, should I pull categories out first, then reference each category as a child, or reference immediately by attribute.

This is what I've been using for < open > somthing < /open >

private String getTextValue(Element ele, String tagName) {
String textVal = null;
NodeList nl = ele.getElementsByTagName(tagName);
if (nl != null && nl.getLength() > 0) {
Element el = (Element) nl.item(0);
textVal = el.getFirstChild().getNodeValue();
}
return textVal;
}

Answer 1

You can reference immediately by attribute. e1.getAttribute("name") will give you the attribute of the category tag.

Answer 2

use

 textVal= e1.getAttribute("name");
