[jQuery] Re: JQuery Won't Parse RSS?

You can also use this generic rss parsing script.

# Script rss.txt
var str source, list
var str rss ; cat $source > $rss
set $wsep="," ; var int count ; set $count = { wen $list }
while ( { sen -c -r "^<item\>&</item\>^" $rss } > 0 )
do
var str item ; stex -c -r "^<item\>&</item\>^" $rss > $item
var int index ; set $index = 1 ; var str line ; set $line=""
var str list2 ; set $list2 = $list
while ($index <= $count)
do
var str tag ; wex -p (makestr(int($index))) $list2 > $tag
var str val ; stex -r -c ("^<"+$tag+">&</"+$tag+"\>^") $rss >
$val
stex -r -c ("^<"+$tag+"\>^]") $val > null
stex -r -c ("[^</"+$tag+"\>^") $val > null
set $line = $line + $val + "\t"
set $index = $index + 1
done
while ( { sen -r "^\n^" $line } > 0 )
sal -r "^\n^" " " $line > null
while ( { sen -r "^<&\>^" $line } > 0 )
sal -r "^<&\>^" "" $line > null
echo $line
done

Save the script as some file C:/rss.txt. Execute it as

script "C:/rss.txt" source"http://feeds.reuters.com/reuters/
businessNews") list("title,link")

or

script "C:/rss.txt" source("http://feeds.reuters.com/reuters/
businessNews") list("title,link,description")

etc.

source() is the source rss feed URL.
list() is a list of values to extract and display. Separate values by
comma.

The first command is showing me the following output as of this
moment. (I have cut off end parts ...)
