How to iterate over plain text segments with the Jericho HTML parser

Question

Hi,

For a Jericho Element, I am trying to find out how to loop over all child nodes, whether an element or plain text.

Now there is Element.getNodeIterator(), but this references ALL descendants within the Element, not just the first descendants.

I need the equivalent of Element.getChildSegments(). Any ideas?

Thanks

Using the methodology from Gunslinger47 above, the following returns immediate (first descendant) child segments for the Element elem:

public static List<Segment> getChildSegments(Element elem) {

 final Iterator<Segment> it = elem.getContent().getNodeIterator();
    final List<Segment> results = new LinkedList<Segment>();
    final List<Element> children = elem.getChildElements();

    while (it.hasNext()) {
     Segment cur = it.next();
     if (!(cur instanceof Tag) && !(cur instanceof CharacterReference) && !cur.isWhiteSpace()) {
      boolean enclosed = false;
      for (Element child : children) {
       if (child.encloses(cur)) { 
        enclosed = true;
       }
      }
      if (!enclosed) results.add(cur);
     } else {
      for (Element child : children) {
       if (child.getStartTag().equals(cur)) {
        results.add(cur);
        break;
       }
      }
     }
    }
    return results;
}
