Answer 1

Your method getSLTag is declared to return an ArrayList<String> but the variable sltag in the xmlTag class is actually an ArrayList<SubChild> hence the type mismatch.

So to answer your additional comment about wanting to get path string from sltag, you will need to iterate over the collection of SubChilds and add each path to a new List of Strings, e.g.

public ArrayList<String> getSLTag(String hltag) {
    List<String> slTags = new ArrayList<String>();
    for(int i = 0; i < xmlTagInfo.size(); i++) {
        if( xmlTagInfo.get(i).hltag == hltag ) {
            for (SubChild child : xmlTagInfo.get(i).sltag) {
                // Your SubChild class actually declares path and name to be an ArrayList of Strings, but surely they should just be Strings?
                slTags.add(child.getPath());
            }
        }
    }
    return slTags;
}
