使用XSLT根据属性值移动XML元素
使用XSLT根据属性值移动XML元素
提问于 2013-01-29 09:16:09
我需要基于属性值将XML元素移动到响应位置。当id的属性值匹配时，元素<m:footnote>应该从<m:endnote>移动到相应的位置。
示例XML:
<m:chapter xmlns:m="http://www.w3.org/1998/Math/MathML">
<m:front>
<m:p>This is <m:footnote id="1"/>para</m:p>
</m:front>
<m:body>
<m:p>This is <m:footnote id="2"/>para</m:p>
<m:p>This is <m:footnote id="3"/>para</m:p>
<m:p>This is <m:footnote id="4"/>para</m:p>
</m:body>
<m:endnote>
<m:footnote id="1">This is footnote 1</m:footnote>
<m:footnote id="2">This is footnote 2</m:footnote>
<m:footnote id="3">This is footnote 3</m:footnote>
<m:footnote id="4">This is footnote 4</m:footnote>
</m:endnote>
</m:chapter>需要输出：
<?xml version='1.0' encoding='UTF-8' ?>
<m:chapter xmlns:m="http://www.w3.org/1998/Math/MathML">
<m:front>
<m:p>This is <m:footnote id="1">This is footnote 1</m:footnote>para</m:p>
</m:front>
<m:body>
<m:p>This is <m:footnote id="2">This is footnote 2</m:footnote>para</m:p>
<m:p>This is <m:footnote id="3">This is footnote 3</m:footnote>para</m:p>
<m:p>This is <m:footnote id="4">This is footnote 4</m:footnote>>para</m:p>
</m:body>
</m:chapter>尝试过的XSLT：
<?xml version='1.0'?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:m="http://www.w3.org/1998/Math/MathML" exclude-result-prefixes="m">
<xsl:output method="xml" encoding="UTF-8" indent="no"/>
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="m:chapter">
<xsl:copy>
<xsl:apply-templates/>
<xsl:for-each select="child::*/descendant::m:footnote">
<xsl:choose>
<xsl:when test="not(parent::m:endnote)">
<xsl:if test="string(self::m:footnote/@id) = string('ancestor::m:chapter/m:endnote/m:footnote/@id')">
<xsl:copy-of select="m:chapter/m:endnote/m:footnote"/>
</xsl:if>
</xsl:when>
</xsl:choose>
</xsl:for-each>
</xsl:copy>
</xsl:template>
<xsl:template match="m:endnote"></xsl:template>
</xsl:stylesheet>回答 1

这应该可以做到：
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:m="http://www.w3.org/1998/Math/MathML" exclude-result-prefixes="m">
<xsl:output method="xml" encoding="UTF-8" indent="no"/>
<xsl:key name="kEndnote" match="m:endnote/m:footnote" use="@id"/>
<xsl:key name="kFootnoteRef" match="m:p/m:footnote" use="@id"/>
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="m:footnote">
<xsl:copy>
<xsl:apply-templates select="@*" />
<xsl:value-of select="key('kEndnote', @id)"/>
</xsl:copy>
</xsl:template>
<xsl:template match="m:endnote[not(m:footnote[not(key('kFootnoteRef', @id))])]" />
<xsl:template match="m:endnote/m:footnote[key('kFootnoteRef', @id)]" />
</xsl:stylesheet>在您的示例输入上运行时，这将生成：
<m:chapter xmlns:m="http://www.w3.org/1998/Math/MathML">
<m:front>
<m:p>This is <m:footnote id="1">This is footnote 1</m:footnote>para</m:p>
</m:front>
<m:body>
<m:p>This is <m:footnote id="2">This is footnote 2</m:footnote>para</m:p>
<m:p>This is <m:footnote id="3">This is footnote 3</m:footnote>para</m:p>
<m:p>This is <m:footnote id="4">This is footnote 4</m:footnote>para</m:p>
</m:body>
</m:chapter>当在删除了第2和第3 <m:p>的示例输入上运行时，这将生成：
<m:chapter xmlns:m="http://www.w3.org/1998/Math/MathML">
<m:front>
<m:p>This is <m:footnote id="1">This is footnote 1</m:footnote>para</m:p>
</m:front>
<m:body>
<m:p>This is <m:footnote id="4">This is footnote 4</m:footnote>para</m:p>
</m:body>
<m:endnote>
<m:footnote id="2">This is footnote 2</m:footnote>
<m:footnote id="3">This is footnote 3</m:footnote>
</m:endnote>
