download and use an xml file

yvanvds · 01-31-2011 02:08 PM

Perhaps I missed something (It wouldn't be the first time), but is there a way to use an xml file on a webserver?

What i try to do is this:

PHP Code:

download.create("http://attr-x.net/updates/version.xml");

.. and a bit later ..

if (download.state() == DWNL_DONE) 
File f(download.data(), download.size()); 

But what is next? I want to use XmlData on this, but the .load function only accepts a filename. I could save it to disk and load it again:

PHP Code:

if (f.writeTry("version.xml")) myxmlData.load("version.xml"); 

But that seems like an unnecessary step. Also I'd have to wait again, because the writing to disk must be finished before trying to load it, i guess.

So is there a way i can put the downloaded file contents directly into a XmlData structure?

Thanks,

yvan

Mmm, how to use that Download structure? I tried to alter the tutorial code a bit to download an xml file instead of an image. But I just end up with an empty file. What's wrong?

PHP Code:

Bool saved;

Bool Init()
{
   download.create("http://attr-x.net/updates/version.xml");
   saved = false;
   return true;
}

/******************************************************************************/
Bool Update()
{
   if(Kb.bp(KB_ESC))return false;

   if(download.state()==DWNL_DONE) // if all data downloaded successfully
   {
      if(!saved) // check if we haven't already created it
      {
         File f(download.data(),download.size()); // create a file from memory data
         f.write("version.xml");
         saved = true;
      }
   }
   return true;
} 

I also tried other files, like jpg images. All save an empty file on disk after downloading is finished.

I'll add reading xml files from memory! smile

File read(download.data(),download.size()); // create a file from memory data
File write; write.write("version.xml");
read.copy(write);
