How to get the first noed's text?

when tree was load ,the node ‘’ is not show,how to get this node’s text,

and how to show the node?

<?xml version='1.0' encoding='iso-8859-1'?>

The root is never showed. In this case root represents itself as storage of all elements of a tree.
If you need a common item on this level - create it:

<?xml version='1.0' encoding='iso-8859-1'?> <tree text="root" id="0"> <tree text="likeroot" id="01"> <item text="Books" id="books" open="1" im0="tombs.gif" im1="tombs.gif" im2="iconSafe.gif" call="1" select="1"> <item text="Mystery &amp; Thrillers" id="mystery" im0="folderClosed.gif" im1="folderOpen.gif" im2="folderClosed.gif"> <item text="Lawrence Block" id="lb" im0="book_titel.gif" im1="book.gif" im2="book_titel.gif"> <item text="All the Flowers Are Dying" id="lb_1" im0="book_titel.gif" im1="book.gif" im2="book_titel.gif"/> <item text="The Burglar on the Prowl" id="lb_2" im0="book_titel.gif" im1="book.gif" im2="book_titel.gif"/> </item> </item> </item> </item> </tree>
