Syntax:
First the QueryPath is separated into path components, then the path
components are evaluated:
'-' - placed in front of the path component, makes the search flat
'/' - select DOM root node (usually the document-element)
'.' - select current node
'..' - select DOM parent node
'*' - select all child elements (either deep or non-deep)
'!x' - evaluate keypath 'x' on node
'?x' - lookup processing instruction 'x' (either deep or non-deep)
'@x' - lookup attribute 'x',
if x is '*', select all attributes (the map)
x may contain a ':' for namespace queries
any other string: select a child-node with the string as the name.
Samples:
"./head/title" - lookup the 'title' node contained in the 'head' child node
"./@name" - lookup the 'name' attribute of the current node
"./?blah" - lookup the PI 'blah' starting with the current node
"./!values" - call 'valueForKey:@"values"' on the current node
"/-title" - flat search for 'title' element
