Shell Programming and Scripting

Need to parse XML like strings from a file.

Using `egrep -A 1 "Panel Temp" "$2" | tail -2` I get the following string:

Code:

<parameter name="Panel Temp" unit="0.1 C"> <value size="1" starttime="06-08-2017 09:36:56.968">95</value>

I want to output:

Code:

{"Panel Temp" 9.5 C}

The 9.5 C is the value of 9 * unit of 0.1 C

I need something that'll work from a shell script on old and new systems. Particularly from IRIX 6.5...Linux 2.4 to Linix 2.6+ kernel based systems.
Korn ksh is the default shell on IRIX and is probably the most limiting factor, i.e. ksh features that'll work on old and new.

Any help appreciated
