If I have a library that contains an edit field, every time i try and
convert the library webpart to an xslt dataview in sharepoint
designer, I get an error message saying there is an invalid xslt
stylesheet. Invalid character.

If I remove the edit field, it converts to a data view with no
problem.

Does anyone know how to convert the webpart with the edit field?

Also, I know you can have a field right click and choose edit but I
need the edit column to make the site consistent with the way it
already works for the existing lists.
