Ah, makes more sense now. The extra 'do' threw me off (I was also
tired when I first looked at it). It would need an identifier to avoid
confusing the parser, though (either that or assign it in an
assignment statement). It looks like you're calling the function
'test'.

function walkTree(root, enter, exit) {
 var node = root;
 start: while (node) {
   enter(node);
   if (node.firstChild) {
     node = node.firstChild;
     continue start;
   }
   while (node) {
     exit(node);
     if (node.nextSibling) {
       node = node.nextSibling;
       continue start;
     }
     if (node == root)
       node = null;
     else
       node = node.parentNode;
   }
 }
}
