I tried sed -n 's/<[^>].*>//gp' example.html but get nothing on screen, it seems the regular expression is not right

Answer 1

sed -n 's/<[^>]*>//gp' test.csv | sed '/^$/d'

You are almost there, the dot(.) you used could match a ">" character, so remove it from you command

the command after pipe is to clear all blank lines

Answer 2

grep should be enough for this if your version supports -P option for PCRE.

$ grep -oP '(?<=>)(.[^<]+)(?=<)' file
This is heading 1
This is heading 2
This is heading 3
This is heading 4
This is heading 5
This is heading 6

Answer 3

Work on your sample

sed -n 's|</\{0,1\}h[0-9]>||gp' YourFile

replace any and on line and if there is a modification, print the line

to be more exact (assuming tag

sed -n 's|^[[:space:]]*<\(h[0-9]>\)\(.*\)</\1|\2|p' YourFile
