parsing an XML file using C++ library tinyxml!
 

Hi all,
I am working with c++ and new to XML. I have a work with TinyXML. I have understood classes and functions of tinyxml. I want to parse my XML file which is like this:

<?xml version="1.0" encoding="utf-8"?>
<users source="URL" challenge="EncodedString" session="String">
<user name="ABC" password="abc" ></user>
<user name="XYZ" password="xyz" ></user>
<source level=""> URL </source>
</users>

I want to parse this xml file using tinyxml so that related data can be transferred to database.

Kindly help
regards

What exactly is your problem? TinyXML is pretty easy to use, is the tutorial not enough?

i have to parse xml files for a school project i'm doing, actually not very difficult w/o libraries due to xml's nice file layout. although, i assume there's probably some way to write shitty xml...

Thanx for ur replies,

I learned some documentation from net and from this link http://www.gamasutra.com/features/20...uerig_01.shtml I found, how to parse XML file using tinyxml. But just to confirm that if I follow that example and write this:

class Login
{
public:
void Parse(TiXmlHandle handle);

protected:
string m_name;
string m_password;
};

void Login::Parse(TiXmlHandle handle)
{
TiXmlElement* section;

section = handle.FirstChildElement( "user" ).Element();
section->QueryFloatAttribute( "name" , &m_name);
section->QueryFloatAttribute( "password" , &m_password);
}

Then it will store the name and password string in m_name and m_password respectively??

Thanx for ur co-operation!
regards

Due to the name of the function (QueryFloatAttribute) it feels like it queries a float attribute. There might be a function for quering strings though. Otherwise you can check out the Attribute(const char*) function. It returns a const char* for you.

A tip is to use the debugger to see if variables have gotten the correct values. Another good way is to use std::cout or printf.

yes!!
Actually I directly copied the snippet so forgot to change that. There is another function QueryValueAttribute..I think it would be useful in this case.

Thanks a lot for ur concern!

http://cvs.hep.ucl.ac.uk/viewcvs/esp...meter&rev=HEAD in this link it is mentioned “#ifdef TIXML_USE_STL” then you can use QueryValueAttribute which is used to parse string. And I don't want to use STL!! So how to do this?

It depends on how you compile TinyXML, if you don't want TinyXML to use std::string then just don't define TIXML_USE_STL anywhere its that simple. If you read the documentation I linked to you would see that. All methods that say they take a std::string will take a const char* if you don't define TIXML_USE_STL.
