Your description is a bit thin on the ground when it comes to detail, but I'd suggest a starting point would be to search for the Transformers with the word "overlayer" in their name. There are several such as the PointOnLineOverlayer that may give you a starting point. That said you 'may' need to consider using the AnchoredSnapper prior to this analysis.

Do as @1spatialdave says, or you could buffer the lines first to find points with X distance. Check out our tutorial on common GIS operations and FME.

Please check pic above, I need to find out how much of red geometry is the same as the green geometry below the red geometry...
