here what i'm trying to achieve is in my XML in toc-title, there is a number followed by content-style, here my output is having 2 <td>
the number before .
Content after .
if there is no other tag except text after ., i'm able to get the text correctly, and i want to apply-templates for the content after ., please let me know how i can get this done.
here is the demo
Thanks
