Hi,
This could be quite a long thread, so please bear with me.
Ok ive got Xerces installed & its compiling the example correctly.
Now im totally new to XML let alone this parser. Ive contructed the
following xml file. I need the file to contain data that can be parsed &
values loaded into predefined variables within my application.. Firstly I
suppose I need to know if my XML file is ok: (the example uses place holders
so author in a real file would be a persons name)
<?xml version="1.0" encoding="ISO-8859-1"?>
<loopcardprj>
<_prjsetup>
<title>untitled</title>
<author>author</author>
<subject>subject</subject>
<card>subject</card>
</_prjsetup>
<_questions>"What Is 5 x 3?","What Is 5 x 5?","What Is 5 x
5?"</_questions>
<_answers>"15","25","10"</_answers>
<_comment>This is an example of a file layout for the
LoopCard Software By
Alex Curtis</_comment>
</loopcardprj>
The XML is well-formed; but I would rather use this structure, in
order to avoid complex application logic to associate a question with
its answer:
<_questions>
<question>
<q>What Is 5 x 3?</q>
<a>15</a>
</question>
<question>
<q>What Is 5 x 5?</q>
<a>25</a>
</question>
<question>
<q>What Is 5 + 5?</q>
<a>10</a>
</question>
</_questions>
(IF OK): I need to know how to use the parser to parse this file & dump the
data into the correct variables. I read that DOMBuilder was the class to
use???
DOMBuilder will build a DOM tree that you will have to navigate
(DOMDocument->getDocumentElement() will give you the pointer to the
"loopcardprj" node; from there, getFirstChild()/getNextSibling() will
give you either text nodes containing whitespace or the
"_prjsetup"/"_questions" element; and so on.. until you will find
some text nodes containing the real data).
Alternatively you can use a SAXParser or a SAX2XMLReader that will
convert the file into a sequence of callbacks (start "loopcardprj"
element; start "_prjsetup" element; start "title" element; found data
"untitled"; end "title" element...); if you just need to convert the
XML file into a C++ data structure, this would be the choice I would made.

Please If you could help, im really new to this XML / Parsing Business...
Many Thanks
