general guidance

hi,

    i'm new to phpxpath.  i've worked with the example a little and have 
begun to get the hang of writing xpath statements.  however, i'm still 
having trouble understanding the best way to use this library.  my 
experience with xml is mostly with a dom parser, so in some ways, i'm 
trying to understand the best way to use this code to do things like 
loop through a series of nodes and process each of those nodes (and 
their children) in specific ways.  Xpath seems to be about referencing 
the data in a node directly, rather than getting to a specific node 
point and working with the children.  i hope i'm making sense here.

    anyway, i'm asking the community if anyone could offer me some more 
sophisticated examples on how they use phpxpath to construct more 
robust code.  i appreciate any help.
