Re: Variable Scope and xsl:if

[Omar López Ruiz <omar at informix dot com>]

    David,

    And what happens if the value that I assign to the variable is not
true or false, and <xsl:call> calls a template that return text (nodes),
and I don't want at all this text. I've tried this:

<xsl:template matches="whatever">
  <xsl:variable name="foo">
    <xsl:choose>
      <xsl:when test="$foo">
        <xsl:value-of select="a value"/>
        <some xsl tags and xsl:call templates (with returning text)> <!--
but I don't want to assign this text!!! -->
      </xsl:when>
      <xsl:otherwise>
        <xsl:value-of select="a different value"/>
        <some other xsl tags>
      </xsl:otherwise>
    </xsl:choose>
    </xsl:variable>
</xsl:template>

    I've found a solution, two <xsl:choose>, one inside the
<xsl:variable> element, with only the <xsl:value-of>, and the other one,
after the first <xsl:choose> with the rest of the xsl elements and
<xsl:call> elements.

    Please, there's a different solution?

    Thanks,

    Omar
