Not sure here whether 10 is the number of <a> elements to generate or the
multiplier. I'll use it for both...

In XSLT 2.0, it's easy (as things often are!)

<xsl:for-each select="@startPage to (@startPage + @pageSize - 1)">
  <a href="tot.htm?skip={10*.}"><xsl:value-of select="."/></a>
</xsl:for-each>

(You might have to cast the attribute values to xs:integer if your source
document doesn't have a schema)

In 1.0 you use the Piez trick of iterating over a sufficiently large but
otherwise arbitrary node-set:

<xsl:for-each select="//node()[position() &lt= $pageSize]">
  <a href="tot.htm?skip={10*(position()-1+$startPage}"><xsl:value-of
select="position()-1+$startPage"/></a>
</xsl:for-each>

having first initialized the two variables.
