Problem with if statement in xslt

Question

I am trying to display an edit button for each row if logged in as admin.

XML:

<vendors>
   <vendor id="1" name="Microsoft" description="1" odd="1"></vendor>
   <vendor id="2" name="Apple" description="1"></vendor>
   <vendor id="3" name="Google" description="1" odd="1"></vendor>
   <security ADMIN="1"></security>
</vendors>

XSLT:

<xsl:template match="vendors">
  <table>
    <thead>
      <tr>
        <xsl:if test="/vendors/security/@ADMIN = '1'">
          <td></td>
        </xsl:if>
        <td>Name</td>
        <td>Description</td>
      </tr>
    </thead>
      <tbody>
        <xsl:for-each select="vendor">
          <tr>
            <xsl:if test="@odd = '1'">
              <xsl:attribute name="class">odd</xsl:attribute>
            </xsl:if>
            <xsl:if test="/vendors/security/@ADMIN = '1'">
              <th><a href="#"><img src='edit.gif'></a></th>
            </xsl:if>
            <td title='Name'><xsl:value-of select="@name" /></td>
            <td title='Description'><xsl:value-of select="@description" /></td>
          </tr>
        </xsl:for-each>
      </tbody>
    </table>
  </div>
</xsl:template>

Right now this doesn't work. When logged in as admin (@ADMIN = "1"), everything works. When logged in with @ADMIN = "", none of the table cells are displayed (only empty rows).

minro issue but the img tag should be self closing to be valid xml — Bob Vale

I've run this through the microsoft xml parser and it performs as expected. What XSLT parser are you using? — Bob Vale

Apart a problem in the output document (not closed img tag and not open div) the XSLT shown is correct and should show the cells Name/Description even when @ADMIN is "" (tested using Saxon).

You might also compare integers directly, as follows:

test="/vendors/security/@ADMIN = 1"

Yes, it does work and I have no idea why it didn't before when I tried it many times in different browsers. Thanks.

It was the <img> tag! The <div> was just missing in my modified example, but when I closed the <img> tag it started working.

What's weird is that the <img> tag works without closing outside of the if statement.

It's always good practice close tags, even if HTML allows you to leave some of them open. That's no relevant from the point of view of a browser, while it's really relevant from the point of view of an XSLT processor. Finally, I suspect your XSLT processor is buggy.
