Rewrite and Redirect iRule v11 using Datagroup

We want to replace a specific string to a specific string but keep the whole remaining URI portion. For example, if original URI is https://qa.company.com/wps/portal/company/personal/banking/checking/index.html, We want to change it to https://qa.company.com/personal/banking/checking/index.html with respond with a 301. We also would like to use a datagroup for additional URI matching. Is there a way to accomplish this using the ProxyPass iRule?

I thought about using something like the following, would this be the best approach? How do I append the rest of the URI? 

set httpuri [string tolower [HTTP::uri]]
     Rewrite/Redirect 
     If "/wps/portal/company/personal" is found, “/wps/portal/company” will be removed and the URI becomes simply “/personal”
    if {$httpuri starts_with "/wps/portal/company/personal"} {
        set httpuri [string replace [HTTP::uri] 0 14]
        HTTP::respond 301 https://[HTTP::header "host"]$httpuri
        return
    }

    You could try something like this. It works with if /wps/portal/company/personal is the name of the object in the data group and is contained in the path it will be replaced with the value of the datagroup object, /personal.

    when HTTP_REQUEST {
    if { [class match [string tolower [HTTP::path]] contains uri_dg]}{
        set matchURI [class match -name [string tolower [HTTP::path] contains uri_dg]
        set newValue [class match -value [string tolower [HTTP::path] contains uri_dg]
        set newURI [string map -nocase "$matchURI $newValue" [HTTP::uri]]
        HTTP::respond 301 noserver Location "https://[HTTP::host]$newURI"
    }
}
