Re: [xsl] XPath weirdness!!

OK. I hope I can be more clear with this email.

Here is part of my XML source:
<Query>
  <SpatialQuery>
   <Buffer distance="100" units="miles">
    <Point x="-122.5281" y="37.635" />
    <Point x="-122.4521" y="37.700" />
    <Point x="-122.4000" y="37.750" />
    <Point x="-122.3100" y="37.820" />
   </Buffer>
  </SpatialQuery>
 </Query>

I want this part of the output to be:
 <MULTIPOINT>
       <POINT x="-122.5281" y="37.635" />
       <POINT x="-122.4521" y="37.700" />
       <POINT x="-122.4000" y="37.750" />
       <POINT x="-122.3100" y="37.820" />
</MULTIPOINT>


This is part of the XSL that I am using to transform the above:
<xsl:when test="//SpatialQuery/Buffer">
<!-- I need the "//" to get back the <MULTIPOINT> and <POINT> tags -->
   <MULTIPOINT>
          <xsl:for-each select="//Point">
                <POINT>
                <xsl:attribute name="x">
                        <xsl:value-of select="//@x"/>  <!--
THIS GIVES ME THE "X" values -->
                </xsl:attribute>
                <xsl:attribute name="y">
                        <xsl:value-of select="/@y"/>   <!-- HERE IF I USE
"//@y" I GET THE "

&x#3c" ERROR -->
                </xsl:attribute>
               </POINT>
        </xsl:for-each>
    </MULTIPOINT>
</xsl:when>
