所以，我想添加像SalMin，SalMax，SalType和SalCurrency这样的新元素作为空元素，如果它们不存在的话。我想在使用xslt转换时这样做。

Answer 1

<xsl:template name="ApplyTemplatesOrCreate">
  <xsl:param name="elemName" select="''" />
  <xsl:param name="elemDefault" select="''" />

  <xsl:variable name="elem" select="*[name() = $elemName]" />

  <xsl:choose>
    <xsl:when test="$elem">
      <xsl:apply-templates select="$elem" />
    </xsl:when>
    <xsl:otherwise>
      <xsl:if test="$elemName != ''">
        <xsl:element name="{$elemName}">
          <xsl:value-of select="$elemDefault" />
        </xsl:element>
      </xsl:if>
    </xsl:otherwise>
  </xsl:choose>
</xsl:template>

致电：

<xsl:call-template name="ApplyTemplatesOrCreate">
  <xsl:with-param name="elemName" select="'SalMin'" />
  <xsl:with-param name="elemDefault" select="'1000'" />
</xsl:call-template>

如果不存在则创建空元素
