Component name look up for connectors

Hello, 

    Can some one help me with dissecting component names. I have a multiple assemblies one has components other has weld lines. Weld lines have base components name in it.

Example  of a weld line component name  

    2 layer line                     

                LA7273333/2-012234 WLD LNS (X02704/X03430)   

    3 layer line

                LA72733425/2-010104 WLD LNS (X513A12/X02704/X03430)

Example of components names 

                   AA6383837/5-XXXX-X02704-A (PLR FRT uPPER RR FRONT)

                  AA671617033/5-XXXX-X03430-A (SHLD HDR REINF)

                  LAA6716635/4-XXXX-X513A12-A (RL RF SD FRT LHS)

 

I would like to look inside the weld line assembly pull out a name of the weld line sort 2 layer of 3 layer based on name inside the ( ), use the naming inside ( ) from a line name, find the components and create a connector. 

 

Thank you for any help
