you may want to look at vtd-xml, the latest and most advanced xml processing api vtd-xml

Sorry, it's a problem with the code formatting as it appears in Wordpress, still having trouble with it. It's bizarre how hard it seems to be to get WordPress not to mess with code snippets... I recommend that you download the Code & Form code library 0001, which includes the Feedparser example.

ive got a problem with this line:
”
for(int i=0; i
”
inside:
”
// print feed entries
for(int i=0; i
println(i+”: “+feed.entry[i]);
”

error: expecting SEMI, found ‘println’

really cant figure out, whats the problem…

thanks anyway

Thanks for the code, Anthony. For some reason my code coloring plugin doesn’t work on text from comments, sorry about that.

This code uses the built-in XML classes to parse OPML -> RSS/Atom feeds

/* * opmlparse -- parse a OPML file, extracting the Feed URLs, * open each feed URL, display feed name, and titles * * Anthony Starks, ajstarks --at-- gmail.com */


import processing.xml.*;
void setup() {

  String url = "http://www.toptensources.com//topten/Jeremy-Zawodnys-Top-10/?display=.o pml";

  String fu;

  String ftitle;

  XMLElement titles[];

  XMLElement feed;

  XMLElement opml = new XMLElement(this, url);

  XMLElement[] outline = opml.getChildren("body/outline");
  for (int i = 0; i < outline.length; i++) {

    fu = outline[i].getStringAttribute("xmlUrl");

    print(fu);
    try {

 feed = new XMLElement(this, fu);

 println("..Ok");

 XMLElement type = feed.getChild(0);

 if (type.getName().equals("channel"))   { /* RSS */

   ftitle = type.getChild("title").getContent();

   titles = type.getChildren("item/title");

 }

 else {

   ftitle = feed.getChild("title").getContent();

   titles = feed.getChildren("entry/title");  /* Atom */

 }

 println(ftitle);
 for (int nt=0; nt < titles.length; nt++) {

   println("  " + titles[nt].getContent());

 }

    }

    catch(Exception e){

 println("..Loading Failed");

    }

  }

}

[...] Code & form » Code: Read RSS feeds in Processing The XML class built into Processing is too basic to handle feeds, it seems. To remedy the situation I’ve cooked up a quick hack using the ROME library for RSS / Atom syndication. (tags: code processing rss reader) [...]

Thanks for this, I started looking into ROME for the same reason, but never had time to finish anything of use. This is great, cheers.
