This is one of those oft-answered questions which is rooted in the difference in world-view between functional and procedural programming, with XSLT being the former camp and PHP being an instance of the latter.

You need to approach this as a problem in recursive template calling. You didn't provide enough XML for me to test this, so I may have something wrong, but try this for a first cut at the problem:

<xsl:template match="total" name="something">
  <xsl:param name="count" select="0" />
  <xsl:variable name="local-count"><xsl:value-of select="following-sibling::node()[name()='skip']" /></xsl:variable>
  <xsl:variable name="local-total"><xsl:value-of select="." /></xsl:variable>
  <xsl:if test="($count + $local-count) &lt; $local-total">
    <!-- whatever passes for 'echo("Print this");' goes here -->
    <xsl:call-template name="something">
      <xsl:with-param name="count"><xsl:value-of select="$count + $local-count" /></xsl:with-param>
    </xsl:call-template>
  </xsl:if>
</xsl:template>
