Lines in a Simulink/Matlab model

[bagmol]

I need som help with lines in a Simulink model. I need to find out all existing lines and their starting- and destination blocks for a specific model.

If you view the model file as text you will find information about the lines at the bottom for example

-------------------
Line {
SrcBlock "Add"
SrcPort 1
DstBlock "Gain"
DstPort 1
}
-------------------
I need the information "Add" and "Gain" and I need to get it only using matlab commands.

I know for example I can do:
> l = get_param('mymodel','Lines')

ans =

4x1 struct array with fields:
Handle
Name
Parent
SrcBlock
SrcPort
DstBlock
DstPort
Points
Branch

So I have 4 lines all with the above properties. But if I try to get the SrcBlock information like this:
>l(1).SrcBlock

ans =

6.0012

all I get is a number wich I guess is the handle but that is not what I need, I need the name the SrcBlock have in the model.

Any help in this matter is appreciated
