[Laszlo-dev] For Review: Change 20080511-hqm-I Summary: fix, to make LzDatapointer.__LZgetNodes work in swf9

[André Bargull]

The elements in the "LzParsedPath#selectors"-Array can be one these types:
i) a String, one of: '/', '..', '*', '.' or a node-name
ii) an Object, structured like {pred: "hasattr" or "attrval", attr: ? [, 
val: ?]}
iii) an Array for range-selection

So, these expressions yield the same result:
> if ( posnext && posnext is Array ){
or
> if ( posnext && !(posnext is String) && posnext['pred'] ==  "range" ){

> swf9 gets an error when the code in lzDatapointer tries to look for a  
> property on

> dereferencing is
> a hash table or not.

> This change verified that the object is not a String, assuming that if  
> not, it must
> be a hash table. Can POSNEXT ever be something besides a hash table or  
> a String?
