Hi , 
I have two servers with plugin details . I want to evaluate a column as Package_installed and Package_shouldbe based on the hostname in separate column .

server2 has multiple packages I want separate row and column for each package_shouldbe and package_installed and hostname field should be same .

hostnamePlugins
server1Plugin Output:
Remote package installed : gnutls-3.6.16-5.el8_6
Should be                : gnutls-3.6.16-6.el8_7

NOTE: The vulnerability information above was derived by checking the
package versions of the affected packages from this advisory. This
scan is unable to rely on Red Hat's own security checks, which
consider channels and products in their vulnerability determinations.
server2Plugin Output:
Remote package installed : httpd-2.4.6-98.el7_9.6
Should be                : httpd-2.4.6-98.el7_9.7

Remote package installed : httpd-tools-2.4.6-98.el7_9.6
Should be                : httpd-tools-2.4.6-98.el7_9.7

Remote package installed : mod_session-2.4.6-98.el7_9.6
Should be                : mod_session-2.4.6-98.el7_9.7

package versions of the affected packages from this advisory. This

Try this:

<<your current search>>
``` Extract installed packages ```
| rex max_match=0 field=Plugins "package installed\s*:\s*(?<installed>\S+)"
``` Extract "should be" names ```
| rex max_match=0 field=Plugins "Should be\s*:\s*(?<shouldBe>\S+)"
``` Pair installed with shouldBe ```
| eval packages=mvzip(installed, shouldBe, "#")
``` Give each pair its own event ```
| mvexpand packages
``` Break pairs apart ```
| eval packages=split(packages, "#")
| eval installed=mvindex(packages, 0), shouldBe=mvindex(packages, 1)
| table hostname installed shouldBe

I have another issue in comparing and want to compare should_be with server_installed_package . Sometime package installed is higher after patching . Example given below for git , if the number 2 < 3 , it should mark as completed , else it should check for the next digit if it is 2. and it should check for another number .
