The root direcory information will be in 1st file(ex level0.xml).the sub directories of root will be in level1.xml file and so on.I need to get the values from these file and display in tree structure. When i click the directory it should read the next level file &amp; display its sub directories and files. How can i do this? Is there any other approach or language to display?</p>
