How to find spcific parameter value from the job in SQL Server - tsql

Question

I am using the below command to find out the script used in job step.
Requirement :
SELECT SUBSTRING(command, 44, 13),
command
FROM msdb.dbo.sysjobsteps
WHERE command LIKE '%--Should provide the default location%';
In the job I would like to find the specific parameter value.
Lets assume in job step I have a command like below
exec sp_backup #backuplocation='c:\temp\',#overwrite='Y' ...
In the above command I would like to fine #backuplocation parameter details i.e 'C:\Temp'. Parameter name is constant in each job.

Answer 1

Assuming that Parameter name is constant in each job. This should do it:
SELECT F1.command,
O.splitdata
FROM
(
SELECT *,
CAST('<X>'+REPLACE(SUBSTRING(F.command, PATINDEX('%#backuplocation%', F.command), LEN(F.command)), ',', '</X><X>')+'</X>' AS XML) AS xmlfilter
FROM msdb.dbo.sysjobsteps F
WHERE command LIKE '%--Should provide the default location%'
) F1
CROSS APPLY
(
SELECT fdata.D.value('.', 'varchar(100)') AS splitdata
FROM f1.xmlfilter.nodes('X') AS fdata(D)
) O;
so for example if I run it on my machine against our server:
SELECT F1.command,
O.splitdata
FROM
(
SELECT *,
CAST('<X>'+REPLACE(SUBSTRING(F.command, PATINDEX('%#db_nm%', F.command), LEN(F.command)), ',', '</X><X>')+'</X>' AS XML) AS xmlfilter
FROM msdb.dbo.sysjobsteps F
WHERE F.command like 'exec dba..mnt_sts #db_nm=''msdb'', #sts_object_recompile_fg= 0'
) F1
CROSS APPLY
(
SELECT fdata.D.value('.', 'varchar(100)') AS splitdata
FROM f1.xmlfilter.nodes('X') AS fdata(D)
) O;
this will return the following:
