rss — RSS

[Error: Irreparable invalid markup ('') in entry. Owner must fix manually. Raw contents below.]

I wrote a code for Fetching LJ content of a community. Am using RSS here. I wrote one XML Parser, It displays the entries in proper format (User can modify the code for his/her choicable format). It also displays the user name and userpic of the person who posted the entry in the community, also it counts the number of comments for that post and displays the comment count.
Also it displays the current music, current mood and the mood icon used for that entry.

This code will be helpful when someone is designing a website for a community and wants to fetch the LJ contents in the site...

I've not yet tested the code for all types of design. If anyone can test the code and find the errors and fix them, it'll be helpful for everyone...

}

// Now to the parsing itself. Starts by creating it:

$xml_parser = xml_parser_create();

// Then setup the handlers:

xml_set_element_handler($xml_parser, "startElement", "endElement");
xml_set_character_data_handler($xml_parser, "characterData");

// Open the actual datafile:

$fp = fopen($backend, "r");

// Run through it line by line and parse:

while ($data = fread($fp, 4096)) {
xml_parse($xml_parser, $data, feof($fp))
or die(sprintf("XML error: %s at line %d",
xml_error_string(xml_get_error_code($xml_parser)),
xml_get_current_line_number($xml_parser)));
}

// Close the datafile

fclose($fp);

// Free any memmory used

xml_parser_free($xml_parser);

?>

But in this code the problem is that it doesn't recognise LJ-cut and doesn't do caching.

If anyone modifies the code and make it efficient then it'll be helpful :)

XML?

Date: 05/09/05 (Computer Geeks) Keywords: rss, xml, web

What's the best - and free - way to add XML syndication feeds to a website?

I'm working on my own site right now (unfortunately, I can't make the whole thing live until the DNS changes to my GoDaddy domain go through), and my goal is to have three separate blogs through Blogger.com...and I want to display a feed from the two secondary blogs on my front page (like have a section for a secondary blog, containing links and the first few lines from each article in that blog...). I know I can use FeedBurner to convert my Atom XML feeds to RSS, but either way, how do I make my site display the XML information?

Thanks in advance!

XML Encoding

Date: 05/26/05 (PHP Community) Keywords: rss, html, xml

I'm writing a lib to produce RSS/Atom feeds for a site.

I have the character “ in some stories.

I have done htmlspecialchars($title), however, this still produces a character that feedvalidator.com don't like in the XML.

How should I correctly trap/encode this (and other similar) characters?

Any Thunderbird RSS gurus out there?

Date: 05/31/05 (Mozilla) Keywords: php, rss, html, xml, web

I just started using Thunderbird as an RSS reader and I'm noticing strange behavior with my feed. If I load up http://www.perturb.org/rss.php in thunderbird the entries it displays are links to web pages. When I view one of those feeds it shows that entry as it is embeded on the webpage. If I look at one of the entries from http://www.lessig.org/blog/index.xml the entry shows the raw text that's in the RSS feed no HTML requests made.

Considering the first feed is from my blog, how do I make Thunderbird show the raw content, instead of the HTML. It's exported correctly. Bloglines sees the content just fine. Is there a Thunderbird setting I'm missing?

RSS newsreaders

Date: 06/08/05 (Computer Geeks) Keywords: rss

Hello, I am interested in getting an RSS newsreader, but I am looking for one with a scrolling bar which would be able to be placed on the top or bottom of my screen (if anyone knows what Winbar is, think of something like that). So far all I have found is newsreaders which come in window format, but which don't have a bar feature (like a stock ticker). If anyone knows of something like this, I would like to know (preferably open source).

aggregate rss or atom feeds

Date: 06/09/05 (Web Development) Keywords: rss

I want a tool or service that i can give multiple rss and/or atom feed url's to, and get back an aggregation.

LiveJournal itself is pretty great at this... but I need the aggregation to be programmatic and on-the-fly.

This could be best solved with source code. I'd imagine someone might rent a service that does this well already.

Open to ideas. YOUR ideas.

PHP doesn't wanna write to a text file.

Date: 06/09/05 (PHP Community) Keywords: php, mysql, rss, database, sql, web

Okay, I'm having a bit of a problem here... I'm trying to create an RSS feed from my MySQL database. Unfortunately though, I can't seem to write to a file. PHP isn't running in safe mode, and the enclosing folder permissions don't seem to make a difference. The file gets created, but no writing occurs, and if the 'is_writeable' statement is taken out, the script runs until it times out and gives an error 500. Anyone have any clues?
