[xml] Rewinding an xmlTextReaderPtr

[Tojo Punnoose <tojo amplewave com>]

Hi.

	I am trying to use the libxml2 libraries for parsing an XML file. I am 
using the reader interface for parsing the file. Currently I am stuck at 
the following problem
	I have written a wrapper function that reads through an xml file and 
returns the 'value' of the 'field name' passed.
Assuming I have an xml file like this...
        <title>money</title>
        <creator>Tojo</creator>
        <location>somewhere</location>
My function returns the following
        getFieldFromFile(reader, "title")  ==> money
        getFieldFromFile(reader, "creator") ==> Tojo
        getFieldFromFile(reader, "location") ==> somewhere.
	But if I change the order of invocation of these function, say 'creator' 
first and 'title' next, I will not be able to get the value of 'title'. 
This is because the reader (of type xmlTextReaderPtr) would have passed 
through the 'title' field, before it reached 'creator' field. Now my 
question is, is there a way to rewind the xmlTextReaderPtr to the beginning 
of the file, without re-opening the actual xml file.
It would be very helpful if you can give me some pointers on this.
thanks and regards
tojo.
