newbie xml - text outer tags
Feb 2nd, 2009, 2:52pm  
Hi,

I just started to use the proXML library.
It works fine, but I am confused by one thing.
I want to read the title, which is not given in the tag.
so it`s easy to get the title attribute "someTitle"  
but I need to read "ZEIT ONLINE: Deutschland".

If you think this is to stupid to be posted, please let me know!


example .xml:
_________________________

<?xml version="1.0" encoding="ISO-8859-1"?>
<rss version="2.0">
<channel>
<title attr="someTitle">ZEIT ONLINE:  Deutschland</title>
<link>http://www.zeit.de/deutschland/index</link>
<description>
Neues aus Deutschland : Aktuelles aus den deutschen Bundesländern
</description>
</channel>
</rss>
______________

.pde:
_______________


import proxml.*;


XMLInOut xmlIO;
XMLElement  title;
XMLElement news1;
XMLElement  channel;


void setup(){
 size(400,400);
 xmlIO = new XMLInOut(this);
 xmlIO.loadElement("zeit_exp.xml");    //read testfile  
}

void xmlEvent(XMLElement element){
 news1=element;
 channel=news1.getChild(0);
 // println(channel);
 title=channel.getChild(0);
 println(title);
  }

void draw(){

}

Do you need proXML? For this task at least, built-in XML support is enough:
Code:
XMLElement xml;

void setup()
{
  xml = new XMLElement(this, "rss.xml"); // rss
  println(xml.getName());
  XMLElement e = xml.getChild(0); // channel
  println(e.getName());
  e = e.getChild(0); // title
  println(e.getName());
  String t = e.getContent();
  println(t);
}

Looking at proXML's API, perhaps what is missing is a call to getText().
