xslt - if then else 或 when-otherwise 的 XSLT 语法

Question

xslt 非常新（仍然）。我认为我需要使用“When-Otherwise”来执行以下操作（如果我错了，请纠正我），因此为以下逻辑寻找一些关于正确语法的指导：

当 'Contribution_Amount' <=0 时，忽略该行，不输出。
否则返回“Contribution_Amount”。

或者如果这更容易/更好，我也可以使用相反的

当 'Contribution_Amount' > 0 时，则 'Contribution_Amount' 否则不产生输出

这是xsl。任何建议或帮助将不胜感激。提前致谢！

这是xml输入。我将其标记为 1.0，因为这是我们最初的开发人员创建的。我不够精通，无法真正了解其中的区别或何时切换，抱歉。

Answer 1

我会将其简化为：

<xsl:variable name="amt" select="sum(current-group()//wd:Current_Period_Result)" />
<xsl:if test="$amt">
    <contribution_Amount>
        <xsl:value-of select="format-number($amt, '0.00')"/>
    </contribution_Amount>
</xsl:if> 

（应该是注释，但是代码太多了）。
