Full Discussion: To get the id value dynamically
Top Forums UNIX for Beginners Questions & Answers To get the id value dynamically Post 303031823 by stomp on Wednesday 6th of March 2019 06:59:53 AM

If you really want the id of the newest match, take RudiCs snippet. If you just assume that the first match is the newest, you can go simpler by using that:

Code:
awk 'match($0,/<a href="([0-9]+)/,res) {print res[1];exit}' data.html

If someone wants to use a parser for more robust operation, one can use this as a starting point:
Code:
xmlstarlet sel -t -v "/html/body/pre" data.html  | awk '/^\s*[0-9]+\// {print $1,$2}'


# output 

1456/ 01-Mar-2019
4561/ 28-Feb-2019

Note: I assume only gnu awk supports match(subject,pattern,array) Other variants of awk only support 2 parameter match like match(subject,pattern), which will cause a syntax error here.
