Re: [xsl] generating numbers for anchor tabindex

Try using xsl:number with level="any":

  <xsl:number level="any" />

That will get you a number for the <a> element amongst *all* the other
<a> elements in the document. If you want to narrow that down, you can
use the 'count' attribute, to for example only count those <a>
elements that have an 'id' attribute:

  <xsl:number level="any" count="a[@id]" />

These are essentially the same as:

  <xsl:value-of select="count(preceding::a) + 1" />

and:

  <xsl:value-of select="count(preceding::a[@id]) + 1" />

respectively.
  
Cheers,

Jeni
