XSLT：获取文本节点并作为多个元素的属性值插入

Question

我正在处理 DublinCore 元数据系统描述的一堆书目条目（更准确地说，是期刊文章）。我想要做的是检索这些数据并以一致的 XML 结构重新排列它们，以便创建满足 PKP specifications and can be uploaded to my OJS 安装的 XML 文件。

虽然我以前从未接触过 XSLT，但经过几天的学习，这是我设法得到的：

等等...

基本上我想为每个<articleItem/>复制<language/>文本节点并将其粘贴为元素articleItem、[=的属性值（用##标记） 16=] (HTML) 和 galley (PDF)。

我尝试了很多不同的解决方案，但是 none 对我有用：实际上我想知道是否有可能得到这个结果...

所以我有点卡在这里；任何帮助，将不胜感激。提前谢谢你。

在 @michael.hor257k 发表评论后编辑：

这是我的尝试，但我知道它根本没有意义，因为我不是在操纵，而只是创建一个已经存在的元素的副本...

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

    <xsl:template match="language">
        <articleItem locale="it_IT" public_id="" language="{node()}"/>
    </xsl:template>
</xsl:stylesheet>

我无法解决这个问题：

同时匹配两个“东西”（我要复制的文本节点和粘贴的目标区域）；
获取第一个并将其打印在不同的位置...

这是我想要得到的结果：

请注意，language 元素不再显示，但其文本节点现在是 articleItem [language="en|fr|es"], galley 的属性值 ( HTML) 和 galley (PDF) [均 => locale="en|fr|es"]

Answer 1

这样试试：

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:strip-space elements="*"/>

<!-- identity transform -->
<xsl:template match="@*|node()">
    <xsl:copy>
        <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
</xsl:template>

<!-- populate articleItem's language -->
<xsl:template match="articleItem/@language">
    <xsl:attribute name="language" select="../language"/>
</xsl:template>

<!-- populate galley's locale -->
<xsl:template match="galley/@locale">
    <xsl:attribute name="locale" select="ancestor::articleItem/language"/>
</xsl:template>

<!-- remove language -->
<xsl:template match="language"/>

</xsl:stylesheet>

已添加：

but what if the attribute name and its value were not set? For instance: <articleItem locale="it_IT">...</articleItem> (without "language" attribute) and <galley>...</galley> (without "locale" attribute)

在这种情况下，模板必须匹配父元素（articleItem 或 galley），复制它，复制现有属性，add/overwrite language属性并将模板应用于子节点 - 例如：

<xsl:template match="articleItem">
    <xsl:copy>
        <xsl:copy-of select="@*"/>
        <xsl:attribute name="language" select="../language"/>
        <xsl:apply-templates/>
    </xsl:copy>
</xsl:template>

XSLT：获取文本节点并作为多个元素的属性值插入

XSLT: get a text node and insert as attribute value of multiple elements

xml

xslt

xslt-2.0

xslt-1.0
