c++ XML file parsing problem -

Hello everybody is my problem, I want to parse a XML file, I just want to change the unit value like

In my name, I type a code in my name c ++ which is the following

  #include & lt; String & gt; # Include & lt; Iostream & gt; # Include & lt; Sstream & gt; # Include & lt; Stdexcept & gt; # Include & lt; List & gt; # Include & lt; Sys / types.h & gt; # Include & lt; Sys / stat.h & gt; # Include & lt; Unistd.h & gt; # Include & lt; Errno.h & gt; #include "/usr/local/include/xercesc/parsers/SAXParser.hpp" #include "/usr/local/include/xercesc/sax/HandlerBase.hpp" #include "/ usr / local / include / xercesc / util / XMLString.hpp "using namespace std; Using the name space xercesc; Int main (int argc, char * args []) {XMLPlatformUtils :: Initialize (); Char * xmlFile = "/home/manish/conf/mapred-site.xml"; Cout & lt; & Lt; XmlFile; SAXParser * pars = new SAXParser (); Parser-> SetDoNamespaces (true); // Optional document handler * docHandler = new handler (); Error Handler * errHandler = (ErrorHandler *) docHandler; Parser-> SetDocumentHandler (docHandler); Parser-> SetErrorHandler (errHandler); Parser-> Parse (xmlFile); The court's & lt; & Lt; Parser-> GetRootGrammar (); Pars removal; Delete DockHandler; Return 0; }    From my side I just saw an address I do not know what to do now? How to use this address? What is pointing to iit? What should I do to change the parameters of the XML file, in which my XML file  
     I want to change "myname" in "name" in this file  
 Can anyone tell me how to do this?   
 
  If this is all you really want to do, why do not you just replace some searches and strings Are: "Tag" by example. Then search for the next "" and "tag" tag after you use it.  
 The above code is WRT: As I mentioned in my, you can not use SAX to modify the XML document. In fact, in your code, you are not defining handler for your specific XML document, so how do you expect it to work? I suggest that you sit and try to understand the Sachs Parser example in examples.

Integrate flash games in android app? -



    3 is a flash game that I want to integrate into a menu / list in the Android app. So when the user selects the game from the list, the game starts with the help of the Android Flash Player.   Is it better or better with webwave?   Is there any good tutorial?   Thank you! Adobe Flash provides a good way: you can create a breeze for the Android app.    Use this to create your menu and compile three games in your air app.   Here are some tutorial links about how to publish AiI for Android applications and:   PART1: AIR for Android, PART2:   Publication for Android apps: Ai:   I do not believe that the Android Flash Player can be launched with a single intention so far, so using Java Android will not solve it (now ) And   and a third approach Whatever you mentioned, it should work - using the webwave.
