Filters on specific nodes in a loop

[priyambada_n168]

Hi,

I need help with respect to filtering specific nodes in loop traversal. I have a sample network as below. Start node will be the node(Label D) and I have to traverse till nodes of label Port. My requirement is to fetch the end nodes based on condition applied on fields of nodes with label-Y.

The condition status='Ready' should be applied on all the nodes with label Y. Based on that the required end nodes should be retrieved- P1 and P2.

I am looking for a query to loop through the edges Edge0, Edge1, Edge2 and Edge3 and apply the filters to fetch P1 and P2.

Thanks in advance.

Try this, modify to your properties and such:

match(d:D{id:0})
match path=(d)-[*]->(p:Port)
with p, [i in nodes(path) where 'Y' in labels(i)] as y_nodes
where all(i in y_nodes where i.status = 'Ready')
return p as port, y_nodes
