thanks very much for that, I didn't realize what can be done with
xsl:number. My count attribute will be quite long since there are so
many things that end up getting transformed into anchors, but it's not
a problem.

Hi Simeon,

I am trying to think of a way to automatically generate numbers for
the tabindex property of html anchors. Since the xml that ends up
getting transformed into the anchor could be at any level within the
document I can't use a simple position().

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" />


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