But in the end a good day was had by all*, especially the spectators:

* Except: Kimi Raikkonen, Robert Kubica, Timo Glock, Takuma Sato, Nelsinho Piquet, Felipe Massa, David Coulthard, Jarno Trulli, Adrian Sutil, Mark Webber, Jenson Button, Anthony Davidson, Sebastian Vettel, Giancarlo Fisichella, Rubens Barrichello

Kimi ended up salvaging a point thanks to Barrichello's disqualification for exiting the pit lane against a red light. This also shifted Champ car champ Sebastien Bourdais to 7th rank (even though he didn't quite finish) and 2 points - not bad for your first f1 in a third tier car (which is why I included him in the list of people who *did* have a good day!

There was an even more awe inspiring FA/18 demonstration but I didn't get any still footage of that. I'll see if my phone-cam video is worth posting later.

Update: Oops, my brain slipped back in time! This post previously (and incorrectly) attributed this spin to Alex Wurz who no longer has an F1 driving seat.

You can transform your xml into sql using xslt. Stealing some bits of code from elsewhere on the net, I can use the following xslt to convert my del.icio.us bookmarks into a set of insert statements:

<?xmlversion="1.0"?>
<!DOCTYPE rdf:RDF [
    <!ENTITY rdf 'http://www.w3.org/1999/02/22-rdf-syntax-ns#'>
    <!ENTITY rss 'http://purl.org/rss/1.0/'>
]>
<xsl:stylesheetversion="1.0"xmlns:xsl="http://www.w3.org/1999/XSL/Transform"xmlns:rdf="&rdf;"xmlns:rss="&rss;">
  <xsl:outputmethod="text"/>

  <!-- main template -->

  <xsl:templatematch="/rdf:RDF">
      <xsl:apply-templatesselect="rss:item" />
  </xsl:template>

  <xsl:templatematch="rss:item">
    insert into links (url, title)
    values (
    '<xsl:call-templatename="sql-escape"><xsl:with-paramname="text"select="rss:title"/></xsl:call-template>',
    '<xsl:call-templatename="sql-escape"><xsl:with-paramname="text"select="rss:link"/></xsl:call-template>'
    );
  </xsl:template>

  <!-- utility functions -->

  <xsl:templatename="sql-escape">
    <xsl:paramname="text"/>
    <xsl:variablename="tmp">
      <xsl:call-templatename="replace-substring">
        <xsl:with-paramname="from">'</xsl:with-param>
        <xsl:with-paramname="to">''</xsl:with-param>
        <xsl:with-paramname="value"select="$text"/>
      </xsl:call-template>
    </xsl:variable>
    <xsl:value-ofselect="$tmp"/>
  </xsl:template>

  <xsl:templatename="replace-substring">
    <xsl:paramname="value" />
    <xsl:paramname="from" />
    <xsl:paramname="to" />
    <xsl:choose>
      <xsl:whentest="contains($value,$from)">
        <xsl:value-ofselect="substring-before($value,$from)" />
        <xsl:value-ofselect="$to" />
        <xsl:call-templatename="replace-substring">
          <xsl:with-paramname="value"select="substring-after($value,$from)" />
          <xsl:with-paramname="from"select="$from" />
          <xsl:with-paramname="to"select="$to" />
        </xsl:call-template>
      </xsl:when>
      <xsl:otherwise>
        <xsl:value-ofselect="$value" />
      </xsl:otherwise>
    </xsl:choose>
  </xsl:template>
  
</xsl:stylesheet>

The command pipeline above uses the postgres psql command, but you can just as easily use this approach with mysql, oracle, sybase, sql server or whatever. Most database vendors/projects these days have some sort of xml functionality built in, but this puts all the processing load on the part of your system that is most difficult to scale. Better, I think, to do as much processing as possible on your application server which you can more easily scale.

You might also be better using xslt to convert to CSV and then using some simple script to slurp the csv into your database - you could then handle insert/update errors gracefully in your script.

The utility sql-escape and replace-substring templates can be placed in a common file and included into your xsl stylesheets via an xsl:import statement. If you have an xsl 2 compatible xslt engine you can use the x:replace() function directly instead of the recursive replace-substring template.
