Default Getting selected item in dropdown to match XML

Been working with a dropdown box that I want the selected default item to be whatever is in the XML for that record.

For example, if I have:

<categories>
  <cat>car</car>
  <cat>truck</car>
</categories>
<record>
  <name>mmm</name>
  <nameCat>car</nameCat>
</record>

I want 'car' to be the value selected in my dropdown box. I have succesfully populated the dropdown box with all of the categories but cannot get the selected placement to work.

Anyone, help?!

Thanks!

Julia

Here is a solution but obviously I don't know the full xml source:
Code:
<root>
  <categories>
    <cat>car</cat>
    <cat>truck</cat>
  </categories>
  <record>
    <name>mmm</name>
    <nameCat>car</nameCat>
  </record>
</root>

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:template match="/">
    <html>
      <head><title>Drop Down</title></head>
      <body>
        <select id="lstCategories">
          <xsl:apply-templates select="root/categories/cat"/>
        </select>
      </body>
    </html>    
  </xsl:template>
  <xsl:template match="categories/cat">
  <xsl:variable name="currentValue" select="text()"/>
  <option value="{$currentValue}">
    <xsl:if test="//record/nameCat[ . = $currentValue]">
      <xsl:attribute name="selected">selected</xsl:attribute>
    </xsl:if>
    <xsl:value-of select="$currentValue"/>
  </option>
 </xsl:template>
</xsl:stylesheet>
