Question

I want to query my Mongodb collection (name: wrappers) and retrieve all documents that have field ‘urls’ that end with ‘.com’

I am not sure on how to query nested documents and also using regex for queries.

I am actually coding it in perl. However queries to run on the mongo shell would also be fine.

Thanks in advance!

Sample Data:

{ "_id" : ObjectId("4e7a34932cd4b16704000000"), "lastArray" : { "desc" : "google", "url" : "google.com", "data" : [
    {
        "name" : "1",
        "xpath" : [ ],
        "nodes" : [ ],
        "type" : "Any Text"
    },
    {
        "name" : "2",
        "xpath" : [ ],
        "nodes" : [ ],
        "type" : "Any Text"
    }



{ "_id" : ObjectId("4e7a34932cd4b16704000001"), "lastArray" : { "desc" : "yahoo", "url" : "yahoo.com", "data" : [
    {
        "name" : "1",
        "xpath" : [ ],
        "nodes" : [ ],
        "type" : "Any Text"
    },
    {
        "name" : "2",
        "xpath" : [ ],
        "nodes" : [ ],
        "type" : "Any Text"
    }

db.wrappers.find({"lastArray.url":{$regex:/\.com$/}});
