getting XML data from Xerces (c++)

I am a latecomer to XML - have to parse an XML file. Our company is using xerces already so I managed to cobble together a sample app (SAX) that displays all the data in a file. However, after parsing is complete I was expecting to be able to call the parser or some other entity that had an internal representation of the file and iterate through the fields/data.

Basically I want to be able to hand it some key or other string(s) and get back strings or collections of key/value pairs. I do not see that. It seems pretty obvious to me that that is a good thing to do. Am I missing something?

Is the DOM parsing what I want, or does that fall short too?

If you use the XercesDOMParser, there is still no way to request a specific key value pair after the document is parsed. I ran into the same problem recently, and while iterating through the DOM tree I stored all the key value pairs in an STL map. Then you can request key value pairs from the map later in the program.

Xerces provides both SAX and DOM processing. SAX parsing doesn't construct a model, so once parsing is finished there is nothing to examine or iterate through. DOM processing produces a tree-structured model which gives you what you want.
