I want to increment a value to concat to a string.

You cannot increment variables ... they are unchanged once bound.


For example:

        <a>
              <b>1</b>
        <b>2</b>
      </a>

      <a>
              <b>3</b>
        <b>4</b>
      </a>

The output would be:

        <b id="b1"/>
        <b id="b2"/>
        <b id="b3"/>
        <b id="b4"/>

Dynamically calculate what you need at each step:


<b id="b{count(preceding::b) + 1}"/>

But, if you just want unique values and you don't care what the values are:

<b id="{generate-id()}"/>

I hope this helps.
