如何删除clumn Order中没有值的记录？

期望的输出：

<Root><output>
    <queries>
        <query name="Test">
            <parameters>
                <parameter>298674,298673,298675,298676</parameter>

                    <column name="Task">272093</column>
                    <column name="FirstAction">2709305</column>

我当前的XSL只删除空节点

<xsl:strip-space elements="*"/>
 <xsl:template match="@*|node()">
  <xsl:copy>
    <xsl:apply-templates select="@*|node()"/>
  </xsl:copy>
</xsl:template>
<xsl:template match="*[not(child::node())]"/>

我似乎无法掌握模板匹配以删除整个“记录”标记... 非常感谢你！

添加一个新模板到删除clumn中没有值的记录

<xsl:template match="record[column[ @name='Order']= '']"/>

此匹配记录在名称为Order的列中没有值，并忽略它们。
