Try changing ../bestReturn to //bestReturn in your test in order to match
bestReturn regardless of where it is located in your document - that seemed
to do the trick on my system using IE5.

P.S. You might want to send future messages in plain text.  Yours came
through as RTF attachments. I've included your message in plain text for
those not able to open the RTF attachments.

>Greetings,

I'm having an extremely frustrating time trying to compare two xml elements
using the following command:

<xsl:if test="ThisThing[. = ThisOtherThing]">do this</xsl:if>

Heck, it won't even work if I try ThisThing[. = ThisThing]. The only way I
can get this to work is if I acutally compare "ThisThing" to a string
 ThisThing[. = '12345'] ).

Here's an example:

*********** EXAMPLE XML ********************

<?xml version="1.0"?>
<portfolio xmlns:dt="urn:schemas-microsoft-com:datatypes">
  <bestReturn>ZCXM</bestReturn>
  <stock exchange="nyse">
    <name>zacx corp</name>
    <symbol>ZCXM</symbol>
    <price dt:dt="number">28.875</price>
  </stock>
  <stock exchange="nasdaq">
    <name>zaffymat inc</name>
    <symbol>ZFFX</symbol>
    <price dt:dt="number">92.250</price>
  </stock>
  <stock exchange="nasdaq">
    <name>zysmergy inc</name>
    <symbol>ZYSZ</symbol>
    <price dt:dt="number">20.313</price>
  </stock>
</portfolio>

*********** EXAMPLE XSL ********************

<?xml version='1.0'?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/TR/WD-xsl";
result-ns="http://www.w3.org/TR/REC-html";>
  <xsl:template match="/">
    <HTML>
      <BODY>
	<B>Best Historical Return: </B><xsl:value-of
select="portfolio/bestReturn"/>
	<BR/><BR/>
	<B><I>My Portfolio</I></B><BR/>
        <TABLE BORDER="2">
          <TR>
            <TD><B>Symbol</B></TD>
            <TD><B>Name</B></TD>
            <TD><B>Price</B></TD>
            <TD><B>Best Return</B></TD>
          </TR>
          <xsl:for-each select="portfolio/stock">
            <TR>
              <TD><xsl:value-of select="symbol"/></TD>
              <TD><xsl:value-of select="name"/></TD>
              <TD><xsl:value-of select="price"/></TD>
              <TD>

<!-- HERE'S MY PROBLEM -->

		<xsl:if test="symbol[. = ../bestReturn]">Yes</xsl:if>

<!-- THE EXAMPLE BELOW WORKS, BUT IT'S COMPARING TO A STRING RATHER THAN
ANOTHER ELEMENT-->

		<xsl:if test="symbol[not(. = 'ZCXM')]">No</xsl:if>
	      </TD>
            </TR>
          </xsl:for-each>
        </TABLE>
      </BODY>
    </HTML>
  </xsl:template>
</xsl:stylesheet>

What am I doing wrong?  Please help me, for sanity's sake.
