Question

如果我遇到以下问题

我需要使用XSLT转换XML以产生<parent.child>value</parent.child>和<parent.child.grandchild>value</parent.child.grandchild>（如果存在Granchild）。另外，如果我不希望特定元素说价格，则不应该打印...请帮助我制作XSLT吗？它应该是通用代码，以便对于任何XML都可以产生以下输出。我们应该得到这样的东西。

<food.name>Strawberry Belgian Waffles</food.name>
    <food.description>
    Light Belgian waffles covered with strawberries and whipped cream
    </food.description>
    <food.calories>900</food.calories>`
and so on..

<?xml version="1.0" encoding="UTF-8"?>
<breakfast_menu>
<food>
    <name>Belgian Waffles</name>
    <price>$5.95</price>
    <description>

Answer 1

以下样式表：

XSLT 2.0

<xsl:stylesheet version="2.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>

<xsl:template match="*">
    <xsl:element name="{ancestor::*[parent::*]/concat(name(), '.')}{name()}">
        <xsl:apply-templates/>
    </xsl:element>
</xsl:template>

</xsl:stylesheet>

应用于您的示例输入，将返回：

结果

<?xml version="1.0" encoding="UTF-8"?>
<breakfast_menu>
      <food>
            <food.name>Belgian Waffles</food.name>
            <food.price>$5.95</food.price>
            <food.description>

            <food.description>

        </food.description>

            <food.description>
        Thick slices made from our homemade sourdough bread
        </food.description>
            <food.calories>600</food.calories>
      </food>
      <food>
            <food.name>Homestyle Breakfast</food.name>
            <food.price>$6.95</food.price>
            <food.description>
        Two eggs, bacon or sausage, toast, and our ever-popular hash browns
        </food.description>

      </food>
</breakfast_menu>

如果您不希望包含诸如price之类的元素，只需添加一个与之匹配的空模板即可。
