Top Forums UNIX for Beginners Questions & Answers Multiline html tag parse shell script Post 303044115 by stomp on Friday 14th of February 2020 04:51:23 AM

here's a suggestion using pup, a html-parser written in go:

pup 'div p text{}' < data.html

# Output:




Explanation: Get all p-Elements with div-elements as parents and output the text data of it.

To get rid of the empty lines, I suggest a small sed command afterwards:

pup 'div p text{}' < data.html | sed '/^\s*$/d'

# Output

Another short demonstration of pup which I shortly used to get the numbers of cases for the coronovirus out of a complex website and into variables(for generating this graph: coronavirus statistics)) with only one combined command:

 read n n n n infected deceased recovered < <(wget -O- -q  \
       | pup 'div[id="maincounter-wrap"]' | pup 'h1,span text{}' | xargs echo)

Pup is found here: pup on Github

As all GO binaries, it's statically linked and quite large in size(4 MB). Precompiled Binaries are available on github(link above).
