How do you go from XML to the actual .mesh?

I am very new to these programs.

I downloaded the Ogre Blender Export and used it but it only converted my model into a XML file and not an acutal .mesh file. Anyone know how to make the jump from XML to .mesh?

Also, I was trying to convert my model (which I made in Solidworks) so that it would appear in ogre. My model was exported from blender in 80 parts (one for each part), is there a way to make it one file vs 80? Any information is greatly appreciated.

hi bukinga
you only need:
1 open new dos command window console
2 used the OgreXmlConverter.exe
