Reading XML stream using unmanaged c++

[Mayur]

Hello All,

My code below sending request to web server and getting response as XML
string.
char* response;
wf.getResponse(response,500);

where outout of above function returns xml string which is stored in
response variable.

response ="<login>
<session_id>50e39f252f247cc8e4ebb40416f16c38</session_id>
<logged_in>TRUE</logged_in>
<voice_enabled>TRUE</voice_enabled>
<ads_disabled>TRUE</ads_disabled>
<user_id>97558</user_id>
-
- <buddy_list>
<user_id>97002</user_id>
<username>unicorn11</username>
<logged_in>FALSE</logged_in>
<game_id>0</game_id>
<user_id>97562</user_id>
<username>yashwant</username>
<logged_in>FALSE</logged_in>
<game_id>0</game_id>
</buddy_list>
<auto_join_channel />
<button_config />
</login>";

I need to parse this string so that i can check output where user is logged
in whats game ID and all these parameter i required to manuoulate
my task.

where i implemeneted this in c# using XmlTextReader which is so simple but i
need it in unmanaged c++ application..


so please help me regarding this....

This questions is wrong for this NG.

If you need to parse XML you can use 3rd party libraries. For example,

MS XML may fit your needs.

Have a look at IXMLDOMDocument interface, method load and around in
documentation (i.e. Platform SDK documentation, or MSDN either online or
from CD).

Your code will look as follows.
//smart pointers, _variant_t, _bstr_t and other usefull stuff:
#include <comdef.h>
#include <comutil.h>
//This is a compiler com support directive that allows MSXML usage:
#import "msxml.dll"
//To the best of my understanding it is better to place the above include
and import directives in stdafx.h
VOID SomeFunc(VOID)
{
//Create XMLDOMDocument smart pointer:
MSXML::IXMLDOMDocumentPtr xmlDocumentPtr(TEXT("MSXML.DOMDocument"));
//URL of the XML file to download goes here.
_variant_t variant =
_variant_t(TEXT(http://yourdomain.com/yourfile.xml));
VARIANT_BOOL isSuccessful = VARIANT_FALSE;
HRESULT hr = xmlDocumentPtr->raw_load(variant, &isSuccessful);
if (SUCCEEDED(hr) && isSuccessful)
{
//Here you have a pointer to xml document object and can read
different settings from it.
}
