rss per blog category

You can do a search for “rss feed per category” or you can read about in the codex

Set up your link to the RSS feed with /wp-rss2.php?cat=x
where x is the ID of your category

that’s great thanks.

After setting up RSS Feed, Adding buttons for my yahoo etc. The Title of the rss feed shows, but the catagory does not. I’de like the title in yahoo to read.
Sec-Filings.com / Company name.

does any one know how I can do this?

Edit wp-rss2.php. On or around line 33, make the <title> element look like this:
<title><?php the_category_rss(): the_title_rss() ?></title>

Only one top level element is allowed in an XML document. Error processing resource ‘https://sec-filings.com/nasdaq/blogs/wp&#8230;

<b>Parse error</b>: parse error, unexpected ‘:’ in <b>/home/sec-fili/public_html/nasdaq/blogs/wp-rss2.php…

Then…
Parse error: parse error, unexpected ‘:’ in /home/sec-fili/public_html/nasdaq/blogs/wp-rss2.php on line 24

Changed to only the_catagory-rss….

<b>Warning</b>
: Invalid argument supplied for foreach() in
<b>/home/sec-fili/public_html/nasdaq/blogs/wp-includes/feed-functions.php</b>
on line
<b>123</b>

I appreciate any help you can give.
Thank you.
