XSL 模板输出大量文本，而不是 HTML。但只有一节

Question

我在使用 XSL 模板时遇到了一些奇怪的情况。大部分输出都很好，但是某个 for-each 循环给我带来了问题。

这是 XML：

<area>
<feature type="Hall">
    <Heading><![CDATA[Hall]]></Heading> 
    <Para><![CDATA[Communal gardens, pathway leading to PVCu double glazed communal front door to]]></Para>

</feature>
</area>

这是我的模板中处理它的部分：

<xsl:for-each select="area">
    <li>
        <xsl:for-each select="feature">
            <li>
                <h5>
                    <xsl:value-of select="Heading"/>
                </h5>
                <xsl:value-of select="Para"/>
            </li>
        </xsl:for-each>
    </li>
</xsl:for-each>

这是输出：

其余的输出都很好 - 我在上面的部分中遗漏了什么？

Answer 1

你不应该到处使用xsl:for-each，而是模板：

    <xsl:template match="area">
        <li>
            <xsl:apply-templates />
        </li>
    </xsl:template>

    <xsl:template match="feature">
        <li>
            <h5>
                <xsl:value-of select="Heading"/>
            </h5>
            <xsl:value-of select="Para"/>
        </li>
    </xsl:template>

我猜你的匹配规则实际上都没有被调用，所以默认模板被调用（这个模板只是输出所有文本，正如你所描述的）。

阅读Understanding How the Default Templates Work 了解更多信息。

更新：

Stephen Denne 发现问题的根本原因是您的 area 元素被包裹在 text 元素中，因此从未被选中，导致调用默认模板，输出文本节点.

Answer 2

您的区域元素在您的文本元素内。

Answer 3

您的样式表有一个与 property 匹配的模板，但您的 XML 中没有可匹配的 property 元素。

因此，默认模板规则是匹配的，它发出文本节点。

如果您根据属性匹配更改模板：

<xsl:template match="property">

到根节点上匹配：

<xsl:template match="/">

你得到以下输出，我认为这是你想要的：

<ul id="property" xmlns:php="http://php.net/xsl">

<ul class="pictures"></ul>
