dynamically change xpath expression with params

[Lonny_Angell@xxxxxxx]

Is this possible?

I need to change both the values in an XPath Expression at runtime. I would like
to do it with Params (something I can pass in to the XSL sheet). Then I could
pass the new values to the Params from the browser or from a Servlet. Here is a
XSL fragment that shows what I'm trying to accomplish. Any Ideas???

Thanks,

<xsl:template match="LogEvents">

<!-- XSL PARAMETERS -->
<xsl:param name="filter" select="string('INFO')"/>
<xsl:param name="selColumn" select="//LogEvents/LogEvent/Type"/>

<xsl:for-each select="LogEvent [  $selColumn=$filter]">
       <xsl:sort select="DATE" order="ascending"/>
       <tr>
      <td class= "tData"><xsl:value-of select="Date"/></td>
      <td class= "tData"></td>
      <td class= "tData"><xsl:value-of select="Time"/></td>
      <td class= "tData"></td>
            <td class= "tData"><xsl:value-of select="Type"/></td>
      <td class= "tData"></td>
    </tr>
    <tr>
      <td class= "tData" colspan="11">  <hr></hr></td>
    </tr>
  </xsl:for-each>
.....
<xsl:template/>
