Blender console: export single mesh using threejs exporter

Question

I'm using Blender 2.76b, threejs exporter v1.5.0; my goal is to export each mesh in the Blender scene. I noticed that if a single mesh is selected, io_three exports that mesh, so I wrote a simple python script executable in console:

import bpy

for ob in bpy.context.scene.objects:
    bpy.ops.object.select_all(action='DESELECT')
    bpy.ops.object.select_pattern(pattern = ob.name)
    bpy.ops.export.three(
      filepath = 'path to folder' + ob.name + ".json",
      option_vertices=True,
      option_faces=True,
      option_normals=True,
      option_uv_coords=True,
      option_face_materials=True,
      option_colors=True)

It creates files with right names, but with wrong content: all the .json files contain exported content of the scene's first mesh.

How could I get the right behavior? Thanks in advance.

The three.js exporter exports either the entire scene or the active object. While you are changing the selection, nothing in your script is changing the active object. The abspath() I used allows you to get a path relative to the blend file by starting the path with '//'

import bpy

for ob in bpy.context.scene.objects:
    bpy.ops.object.select_all(action='DESELECT')
    if ob.type == 'MESH':
        ob.select = True
        bpy.context.scene.objects.active = ob
        bpy.ops.export.three(
          filepath = bpy.path.abspath('//' + ob.name + ".json"),
          option_vertices=True,
          option_faces=True,
          option_normals=True,
          option_uv_coords=True,
          option_face_materials=True,
          option_colors=True)
