At first you should judge if a node has childnodes (0)? If it has.you should get the length of childnodes (1) and get each childnode's nodetype (2).Here you can use a Switch to judge the childnode's nodetype.1 means the type of child is node,3 means the type of child is text.
0. ->hasChildNodes()
1. ->Getlength()
2. ->GetnodeType()
