Cocos2d-x in XML analysis and data storage

Inadvertently play the game of the week, hey, time is always playing so fast when.

。。

So today I decided to look at XML that was not very familiar to me before, and the data was stored in XML before the game. But this one is still a colleague doing, so not very familiar with),

Looked at the XML and parsing methods he wrote, and then improved it himself, so come up with a simple summary and share

The main concerns are:

1. XML creation

Analysis of 2.xml

3. Save the parsed XML data with a vector;

For example, the following: (after writing the XML, the simplest check syntax error is to open with IE browser to see, can open the syntax is correct)

<?xml version= "1.0" encoding= "Utf-8"?
><mineral><mineral><type>1</type><times>100</times><p>20</p ></mineral><mineral><type>4</type><times>100</times><p>20</p ></mineral><mineral><type>5</type><times>100</times><p>20</p ></mineral></Mineral>

Here I created a new XML named "Mineral.xml" in the form of an online XML writing format.

(mineral is the meaning of the mine, I have arbitrarily written 3 types of ore in XML.) Each ore has its own type, magnification, probability)

Then save it in the resource directory and create a new Cocos2d-x project,

The following post the main parsing code

. h file

#ifndef __helloworld_scene_h__#define __helloworld_scene_h__#include "cocos2d.h" #include <string> #include <vector>typedef struct mineral{int times; int type;int p;} *ptrmineral;class helloworld:public cocos2d::cclayer{public:    virtual bool init ();      Static cocos2d::ccscene* scene ();    void Menuclosecallback (ccobject* psender);    BOOL Readminearlxml (); void Displayvec ();    

. cpp Files

#include "HelloWorldScene.h" #include ". /support/tinyxml2/tinyxml2.h "using namespace TINYXML2; USING_NS_CC;    ccscene* Helloworld::scene () {Ccscene *scene = Ccscene::create ();    HelloWorld *layer = Helloworld::create ();    Scene->addchild (layer); return scene;} BOOL Helloworld::init () {if (!    Cclayer::init ()) {return false;  }readminearlxml ();    Displayvec (); return true;} BOOL Helloworld::readminearlxml () {tinyxml2::xmldocument* xmlData = new tinyxml2::xmldocument (); unsigned long nSize; const char *pxmlbuffer = (const char*) ccfileutils::sharedfileutils ()->getfiledata ("Xml/mineral.xml", "RB",& NSize); if (NULL = = Pxmlbuffer) {cclog ("read Mineral.xml Failed");} Else Cclog ("star read Mineral.xml"); Xmldata->parse (pxmlbuffer,nsize); XMLElement *rootnode = Xmldata->rootelement (); if (!rootnode) {return false;} xmlelement* Curnode = rootnode->firstchildelement ("mineral"); while (null!= Curnode) {ptrmineral pmineral =new Mineral ();p Mineral->type = (atoi) (CurnOde->firstchildelement ("type"))->gettext ());p mineral->times = (atoi) ((Curnode->firstchildelement (" Times "))->gettext ());p mineral->p = (atoi) ((Curnode->firstchildelement (" P "))->gettext ()); m_ Pmineralvec.push_back (pmineral); curnode = Curnode->nextsiblingelement ("mineral");} Delete Xmldata;return true;} void HelloWorld::d Isplayvec () {Cclog ("*********m_pmineralvec*********"); for (int i = 0; I<m_pmineralvec.size (); i++ ) {Cclog ("<mineral>"); Cclog ("<type> =%i </type>", M_pmineralvec[i]->type); Cclog ("<times> =%i </times>", m_pmineralvec[i]->times); Cclog ("<p> =%i </p>", m_pmineralvec[i]->p); Cclog ("</mineral>");}} void Helloworld::menuclosecallback (ccobject* psender) {#if (Cc_target_platform = = CC_PLATFORM_WINRT) | | (Cc_target_platform = = CC_PLATFORM_WP8) Ccmessagebox ("You pressed the Close button. Windows Store Apps do not implement a close button. "," "Alert"); #else ccdirector::shareddirector ()->end (); #if (cc_target_platform = = Cc_platform_ios) exit (0); #endif #endif} 

The above includes XML parsing, XML data display, respectively:

Show demo samples such as the following:

Star Read mineral.xml*********m_pmineralvec*********<mineral><type> = 1 </type><times> = 100 </times><p>     = </p></mineral><mineral><type> = 4 </type><times > = + </times><p>     = </p></mineral><mineral><type> = 5 </type> <times> = </times><p>     = </p></mineral>

Control the program. Output and previously created XML consistency, so that the XML at the resolution OK that, it is not very easy AH
