Question

I have an XML feed (this) in a single line so to extract the data I need I can do something like this:

sed -r 's:<([^>]+)>([^<]+)</\1>:&\n: g' feed | sed -nr '
    /<item>/, $ s:.*<(title|link|description)>([^<]+)</\1>.*:\2: p'

since I can’t find a way to make first sed call to process result as different lines.

Any advice?

My goal is to get all data I need in a single sed call

Answer 1

sed -rn -e 's|>[[:space:]]*<|>\n<|g
/^<title>/ { bx }
/^<description>/ { b x }
/^<link>/ { bx }
D
:x
s|<([^>]*)>([^\n]*)</\1>|\1=\2|;
P
D' rss.xml
