asp.net XmlDocument gets the first node and deletes the root node method

XML technology to store data and documents is a very easy thing, the. NET Framework in its namespace System.Xml provides a convenient way to manipulate XML class XmlDocument, which is easy to use, XmlDocument is actually a simple tree, let's take a look at about XmlDocument get the first node and delete the root node method

#include "stdafx.h"

using namespace System;
using namespace System::xml;

void Navigate (XmlNode ^node, int depth)
{
if (node = = nullptr)
Return

Console::WriteLine (depth);
Console::WriteLine (Node->nodetype.tostring ());
Console::WriteLine (Node->name);
Console::WriteLine (Node->value);

    if (node->attributes!= nullptr)
    {
         for (int i = 0; i < node->attributes->count; i++)
        { br>             Console::WriteLine (depth+1);
            Console::WriteLine (node->attributes[i ]->name);
            Console::WriteLine (node->attributes[i ]->value);
       }
   }
    Navigate (Node->firstchild, depth+1);
    Navigate (node->nextsibling, depth);
}

void Main ()
{
XmlDocument ^doc = gcnew XmlDocument ();
Try
{
XmlReader ^reader = Xmlreader::create (".. Monsters.xml ");
Doc->load (reader);
Reader->close ();
XmlNode ^node = doc->firstchild;

Navigate (node, 0);
}
catch (Exception ^e)
{
Console::WriteLine ("error occurred: {0}", e->message);
}
}

Delete root node

#include "stdafx.h"

using namespace System;
using namespace System::xml;
using namespace System::xml::xpath;

void Navigate (XPathNavigator ^nav, int depth)
{
Console::WriteLine (depth);
Console::WriteLine (Nav->nodetype.tostring ());
Console::WriteLine (Nav->name);
Console::WriteLine (Nav->value);

    if (nav->hasattributes)
    {
         Nav->movetofirstattribute ();
        do {
             Console::WriteLine (nav->name);
            Console::WriteLine (nav->value);
       }
        while (Nav->movetonextattribute ());
        nav->movetoparent ();
   }

    if (Nav->movetofirstchild ())
    {
         Navigate (NAV, depth+1);
        nav->movetoparent ();
   }
    if (Nav->movetonext ())
        Navigate (nav, depth );
}

Void Main ()
{
    xmldocument ^doc = gcnew XmlDocument ();
    try
     {
        doc->load (".. Monsters.xml ");
        XPathNavigator ^nav = Doc->createnavigator ();
        nav->movetoroot ();
        Navigate (nav, 0);
   }
    catch (Exception ^e)
    {
        Console::WriteLine ("error occurred: {0}", e->message);
   }
}
