Or install it yourself as:

    $ gem install graphml2json

## Usage

### From ruby

```

>> require 'open-uri'

>> require 'graphml2json'

>> data = open('http://graphml.graphdrawing.org/primer/attributes.graphml').read

=> "\n\n\n  \n    yellow\n  \n  \n  \n    \n      green\n    \n    \n    \n      blue\n    \n    \n      red\n    \n    \n    \n      turquoise\n    \n    \n      1.0\n    \n    \n      1.0\n    \n    \n      2.0\n    \n    \n    \n    \n    \n      1.1\n    \n  \n\n"

>> Graphml2Json.generate(data)

=> "{\"nodes\":[{\"name\":0,\"d0\":\"green\"},{\"name\":1},{\"name\":2,\"d0\":\"blue\"},{\"name\":3,\"d0\":\"red\"},{\"name\":4},{\"name\":5,\"d0\":\"turquoise\"}],\"edges\":[{\"source\":0,\"target\":2,\"d1\":\"1.0\"},{\"source\":0,\"target\":1,\"d1\":\"1.0\"},{\"source\":1,\"target\":3,\"d1\":\"2.0\"},{\"source\":3,\"target\":2},{\"source\":2,\"target\":4},{\"source\":3,\"target\":5},{\"source\":5,\"target\":4,\"d1\":\"1.1\"}]}"

```

### From a terminal

You can also invoke the `graphml2json` utility from the command line. It takes stdin as input.

```

$ curl http://graphml.graphdrawing.org/primer/attributes.graphml | graphml2json | json_pp

{

   "nodes" : [

      {

         "d0" : "green",

         "name" : 0

      },

      {

         "name" : 1

      },

      {

         "name" : 2,

         "d0" : "blue"

      },

      {

         "name" : 3,

         "d0" : "red"

      },

      {

         "name" : 4

      },

      {

         "d0" : "turquoise",

         "name" : 5

      }

   ],

   "edges" : [

      {

         "d1" : "1.0",

         "source" : 0,

         "target" : 2

      },

      {

         "target" : 1,

         "d1" : "1.0",

         "source" : 0

      },

      {

         "source" : 1,

         "d1" : "2.0",

         "target" : 3

      },

      {

         "target" : 2,

         "source" : 3

      },

      {

         "source" : 2,

         "target" : 4

      },

      {

         "source" : 3,

         "target" : 5

      },

      {

         "d1" : "1.1",

         "source" : 5,

         "target" : 4
