You are including a library that exposes a contents_manager class, but
you didn't add the corresponding LIB file in the 'additional libraries'
(you should know the name of the library, contents_manager is not part
of Xerces)

So it seems I have added properly the folder but it does not work. This

I don't know if I need to configure anything more... I am so sorry, but
can you help me, please? I promise you that as soon as I can link properly I
will ask more "interesting" questions..haha.
Thank you a lot,

2007/11/29, Alberto Massari <[EMAIL PROTECTED]>:
Javier,
the same operation you did for the include folder should be done for the
lib folder (using the Link property page of the Project properties if
you want to fix just this project, or using the VC++ Directories
property page in the Tools | Options menu, after selecting Library files
in the combo box).
In case you didn't already do it, you also need to list xerces_2.lib
(for release builds) and xerces_2D.lib (for debug builds) in the
'additional libraries' entry of the project properties.

PS: Jesse, thanks a lot for your explanation about System.XML and its
features. I am trying to design an application as multiplatform as
possible
and now that I have started with Xerces I would like to use it. But
it's
good to know all the alternatives out there. =).
2007/11/28, Jesse Pelton <[EMAIL PROTECTED]>:
Regarding System.XML versus Xerces: Xerces exists to provide a
solid,
open-source, cross-platform implementation of certain XML standards
for C++
developers. Almost all C++ developers are using unmanaged code; I
think
you're the first I've heard of using Xerces with managed C++.
To the extent that you're in a managed-code environment, Mono's
implementation of System.XML may fulfill the same requirements. If
you're targeting Windows exclusively, the cross-platform issue is of
no
consequence; you'll use the Microsoft implementation. My
understanding is
that System.XML is well-designed and robust, but I can't vouch for
that
myself. That leaves openness; if that's not important for your
project,
System.XML would probably be at least as good a fit as Xerces (and I
imagine there's a large community of managed code developers who can
help
you out, though not one of them is as good as Alberto). Using
System.XML would avoid redundancy: you wouldn't have to distribute,
and
your developers wouldn't have to understand, an additional library.
This is not to say that you shouldn't use Xerces; it's a great
library. Just know your options.

Subject: Re: How to parse using DOM
Alberto,
Thanks again. Everything worked fine.
By the way, as I use getNodeValue and getNodeName to process and
assign
them
to my C++ structures I need to parse the XMLCh* returned value to
String^
buy I couldn't find any way to do it. Any idea?
Jesse,
That's a good question..xD. There are many reasons why I am trying
to
use
Xerces in order to parse and create XML files. Maybe you'll find
them
stupid.
Firstly, I am an absolute newbie with C++ as with Xerces (as you
have
already realized). So, I did no research on XML classes offered by
the
.NET
framework as I didn't know them.
Secondly, I am developing an application based on a previous version
which
was developed by another person, who based his app on Xerces to
parse
XML
files. The problem is that his design didn't take into account
creating
or
writing on XML files, only parsing and reading, so he used the SAX
API.
Then, I had to switch from SAX to DOM and facing all the problems it
implies
(creating a NEW app).
Thirdly, I thought I could find some help if I based my design on a
open
source solution like Xerces is, and here it is.
Then, if you tell me that it is worth for me working with the
System:XML
files, then I would think about it..haha. But then, what is Xerces
for
if
everybody can manage their XML files with these classes?
Cheers,
Javi
2007/11/28, Jesse Pelton < [EMAIL PROTECTED]>:
Just out of curiosity, if you're using managed code, why aren't you
using
the System.XML classes?

Subject: Re: How to parse using DOM
Hi there.
Now I can compile the source code file where I have implemented (or
tried
it...) the DOM parser, some errors have appeared. As they seem
quite
simple
I hope you could help me again:
The method in file.cpp is like this (I have followed the guidelines
< http://xerces.apache.org/xerces-c/program-dom.html>on Xerces
site,
except
for the exception treatment...):
void contents_manager::load_guide(String^ xml_path){
XMLPlatformUtils::Initialize();
XercesDOMParser* parser = new XercesDOMParser();
parser->parse(xml_path);
DOMNode* root = parser->getDocument(); //child_aux1 will be the
first
child of root
DOMNode* child_aux1, child_aux2, child_aux3, child_aux4,
child_aux5,
child_aux6, child_aux7; // Compiling errors referring to this line
//...
In file.h this is included:
#include "../include/gincludes.h"
#include "../content/content.h"
#include <xercesc/dom/DOM.hpp>
#include <xercesc/dom/DOMImplementation.hpp>
#include <xercesc/dom/DOMImplementationLS.hpp>
#include <xercesc/dom/DOMWriter.hpp>
#include <xercesc/util/PlatformUtils.hpp>
#include <xercesc/parsers/XercesDOMParser.hpp>
#include <xercesc/dom/DOM.hpp>
#include <xercesc/util/XMLString.hpp>
#include <xercesc/util/PlatformUtils.hpp>
using namespace System;
XERCES_CPP_NAMESPACE_USE
// class definition...
Then, when compiling a lot of errors appear saying that it can not
be
done
as I am working with abstracts, referring to the previous red
line...

Any idea of what I need to do regarding this error?
By the way, as you may have seen on the arguments of my method, the
name/path of the XML file is received with String^ type, so, as I
need
to
have a char* as an argument for parse->parse(file_name), how can I
parse
it?
Thank you very much,
Javi
2007/11/28, Sven Bauhan <[EMAIL PROTECTED]>:
This is not true. std::string and UTF-8 are fully compatible, as
long
as
you make no assumptions about chopping things up at arbitrary
indices,
or
the relationship of Unicode code points and UTF-8 code units. At
any
rate,
with a double-byte or multi-byte locale code page, you'd have the
same
issues.
I do not really understand what you want to say here. As far as I
know
std::string stores strings in single byte units. In UTF-8 the
units
have
variable length between 1 and 4 bytes. So I cannot see a match
here.
I thought to use UTF-8 with the STL you need something like
std::basic_string<UTFChar>.
Could you tell me, how to transcode the XMLChar* correctly using
UTF-8?
Sven
