I'm working on a custom XSLT and have hit a snag.  I have a Title column but want to completely hide the title (and line break) when a record has no Title.

 Here's a code snippet:

  <xsl:template match="udt:Data" mode="list">
    <div class="normal">
      <xsl:call-template name="EditLink" />
      <b>
        <xsl:value-of select="udt:Name" disable-output-escaping="yes" />
      </b>
      <br />
      <xsl:if test="@udt:Title">
        <xsl:value-of select="udt:Title" disable-output-escaping="yes" />
        <br />
      </xsl:if>
    </div>
    <br />
  </xsl:template>

I finally got it working.  I had to use test="udt:Field!='  ' "  (spacing added between quotes to clarify this on the forums...no spacing between the single quotes).

  <xsl:template match="udt:Data" mode="list">
    <div class="normal">
      <xsl:call-template name="EditLink" />
      <b>
        <xsl:value-of select="udt:Name" disable-output-escaping="yes" />
      </b>
      <br />
      <xsl:if test="udt:Title!=''">
        <xsl:value-of select="udt:Title" disable-output-escaping="yes" />
        <br />
      </xsl:if>

      <xsl:if test="udt:Fax!=''">
        Fax: <xsl:value-of select="udt:Fax" disable-output-escaping="yes" />
        <br />
      </xsl:if>
    </div>
    <br />
  </xsl:template>

I was just the syntax for "not equals" that was causing the problem.  I'm surprised that syntax isn't listed on more sites/examples of xsl:if.
