XSL 从多个 XML 字段创建新元素，包括一些具有相同名称的字段

Question

我正在尝试通过将多个元素（一些具有相同名称）连接到一个新元素中来创建一个新的 XML 元素。我可以通过加入 Publisher 元素来创建新元素，但我不确定如何继续。最终结果将是一个新的 |包含键、作者、标题和出版商的定界元素。 multi-valued 字段将以逗号分隔。我可以使用 XSL 1.0 或 2.0。谢谢

        <xsl:value-of select="."/>
    </xsl:template>
</xsl:stylesheet>

Answer 1

将您的 Record 模板更改为以下内容并省略最后一个模板 <xsl:template match="Publisher/text()">。

<xsl:template match="Record">
    <xsl:copy>
        <xsl:apply-templates select="node()|@*" />
        <Combined>
            <xsl:for-each select="*[not(self::Entrydate)]">
                <xsl:choose>
                    <xsl:when test="name() = name(preceding-sibling::*[1])">, </xsl:when>
                    <xsl:when test="position() = 1" />
                    <xsl:otherwise>|</xsl:otherwise>
                </xsl:choose>
                <xsl:value-of select="." />
            </xsl:for-each>
        </Combined>
    </xsl:copy>
</xsl:template>

Answer 2

我会做：

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>

<xsl:template match="Record">
    <xsl:copy>
        <xsl:apply-templates/>
        <Combined>
            <xsl:value-of select="Key, string-join(Author, ','), string-join(Title, ','), string-join(Publisher, ',')" separator="|"/>
        </Combined>
    </xsl:copy>
</xsl:template>

</xsl:stylesheet>

P.S。应该注意的是，这里有一个潜在的假设，即 none 的连接值将永远包含 , 或 | 定界字符。这似乎是一个非常大胆的假设——尤其是。关于出版物标题中的逗号。
