(That isn't well-formed -- you have 'tag1' start tags and 'tag' end
tags.)

You can find all the 'tag' elements that contain some text with:

  tag[string()]

You can find the first such 'tag' element with:

  tag[string()][1]

To get its position, you could count how many preceding sibling 'tag'
elements it has, and add one (to get the normal 1-based counting
scheme):

  count( tag[string()][1]/preceding-sibling::tag ) + 1

Cheers,

Jeni
