How to get subgraph where the node is located?

#1

Hi,
My graph like this:


now i want to filter out two nodes ( #70:0 and #72:0 ) and their subtree ,like this:

Supplementary explanation:
The class name of #34:2 is ‘Class_A’.
The class name of #65:0 , #70:0 , #72:0 is ‘Class_B’.
And Class_B has one property PROP1
#65:0.PROP1 = 1;
#70:0.PROP1 = 2;
#72:0.PROP1 = 3;

I tried to do this:

MATCH {class:Class_A,where:(@rid = #34:2)}
    .( bothE(){} .bothV(){ while:( PROP1 > 1 ) } )
{while:( $depth <2 ) } RETURN $pathelements

but it doesn’t work.

How can I write a query with a MATCH ?

Regards
