我有一个xml结构,看起来有点像这样:
<Page>
<Id>Page1</Id>
<Content>
<Header>This is the Header</Header>
<Body>This is the body</Body>
<Nested>
<NestedItem>
<Id>N1</Id>
<Content>This is a nested element</Content>
</NestedItem>
<NestedItem>
<Id>N2</Id>
<Content>This too is a nested element</Content>
</NestedItem>
</Nested>
</Content>
<Localizations>
<Localization>
<Locale>ES</Locale>
<Content>
<Header>Esta un caballo</Header>
<Body>Esta body</Body>
<Nested>
<NestedItem>
<Id>N2</Id>
<Content>Esta una element nestado</Content>
</NestedItem>
</Nested>
</Content>
<Localization>
</Localizations>
</Page>在xslt转换之后,我将变量"ES“传入其中,在本例中,我希望它看起来像这样:
<Page>
<Id>Page1</Id>
<Content>
<Header>Esta un caballo</Header>
<Body>Esta body</Body>
<Nested>
<NestedItem>
<Id>N1</Id>
<Content>This is a nested element</Content>
</NestedItem>
<NestedItem>
<Id>N2</Id>
<Content>Esta una element nestado</Content>
</NestedItem>
</Nested>
</Content>
</Page>也就是说,我想翻译在本地化中有相应元素的元素,但在有原始文本的地方保留原始文本。问题是content-element的结构可能是未知的,所以我不能在xsl-file中使用特定的标记名。
到目前为止,我得出了以下结论:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" encoding="utf-8" doctype-public="-//W3C//DTD XHTML 1.0 Transitional//EN" doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"/>
<xsl:param name="locale"></xsl:param>
<xsl:template match="/" name="foo">
<xsl:for-each select="./*">
<xsl:if test="name() != 'Localizations'">
<xsl:element name="{name()}">
<xsl:variable name="elementName" select="name()"/>
<xsl:variable name="elementId" select="Id"/>
<xsl:variable name="elementContent">
<xsl:value-of select="./text()" />
</xsl:variable>
<xsl:variable name="localContent">
<xsl:for-each select="./ancestor::Page[1]/Localizations/Localization">
<xsl:if test="./Locale = $locale">
<xsl:copy-of select="*[name()=$elementName]/*"/>
</xsl:if>
</xsl:for-each>
</xsl:variable>
<xsl:copy-of select="$localContent"/>
<xsl:call-template name="foo"/>
</xsl:element>
</xsl:if>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>它输出xml,但是它在content-tag中创建了元素的副本,并且只有西班牙语内容,其他的标签保持为空。在这一点上,我走的是正确的道路吗?任何指针都是有用的,xslt指南很难找到,我在这里试着自学……

此转换
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:key name="kContentByElName" match="Localization/Content/*"
use="name()"/>
<xsl:key name="kNestedById" match="Localization/Content/Nested/NestedItem"
use="Id"/>
<xsl:template match="node()|@*">
<xsl:copy>
<xsl:apply-templates select="node()|@*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="/*/Content/*[not(self::Nested)]/text()">
<xsl:variable name="vTranslation"
select="key('kContentByElName', name(..))"/>
<xsl:value-of select="$vTranslation | self::node()[not($vTranslation)]"/>
</xsl:template>
<xsl:template match=
"NestedItem[not(ancestor::Localization)]/Content/text()">
<xsl:variable name="vTranslation"
select="key('kNestedById', ../../Id)/Content"/>
<xsl:value-of select="$vTranslation | self::node()[not($vTranslation)]"/>
</xsl:template>
<xsl:template match="Localizations"/>
</xsl:stylesheet>在所提供的XML文档上应用时的
<Page>
<Id>Page1</Id>
<Content>
<Header>This is the Header</Header>
<Body>This is the body</Body>
<Nested>
<NestedItem>
<Id>N1</Id>
<Content>This is a nested element</Content>
</NestedItem>
<NestedItem>
<Id>N2</Id>
<Content>This too is a nested element</Content>
</NestedItem>
</Nested>

<Localizations>
<Localization>
<Locale>ES</Locale>

<Body>Esta body</Body>

<NestedItem>
<Id>N2</Id>
<Content>Esta una element nestado</Content>
</NestedItem>
</Nested>
</Content>
</Localization>
</Localizations>
</Page>生成所需的、正确的结果
<Page>
<Id>Page1</Id>
<Content>
<Header>Esta un caballo</Header>
<Body>Esta body</Body>
<Nested>
<NestedItem>
<Id>N1</Id>
<Content>This is a nested element</Content>
</NestedItem>
<NestedItem>
<Id>N2</Id>
<Content>Esta una element nestado</Content>
</NestedItem>
</Nested>
</Content>
</Page>注意到
这是一个纯XSLT 1.0 solution.

此样式表:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:param name="pLang" select="'ES'"/>
<xsl:key name="kElementByLang"
match="Localization/Content/*[not(self::Nested)]|
Localization/Content/Nested/NestedItem"
use="concat(ancestor::Localization/Locale,'++',
name(),'++',Id)"/>
<xsl:template match="node()|@*" name="identity">
<xsl:copy>
<xsl:apply-templates select="node()|@*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="Localizations"/>
<xsl:template match="Page/Content//*">
<xsl:variable name="vMatch"
select="key('kElementByLang',
concat($pLang,'++',
name(),'++',
Id))"/>
<xsl:apply-templates select="$vMatch"/>
<xsl:if test="not($vMatch)">
<xsl:call-template name="identity"/>
</xsl:if>
</xsl:template>
</xsl:stylesheet>输出:
<Page>
<Id>Page1</Id>
<Content>
<Header>Esta un caballo</Header>
<Body>Esta body</Body>
<Nested>
<NestedItem>
<Id>N1</Id>
<Content>This is a nested element</Content>
</NestedItem>
<NestedItem>
<Id>N2</Id>
<Content>Esta una element nestado</Content>
</NestedItem>
</Nested>
</Content>

下面是一个XSLT2.0样式表(您可以使用Saxon 9、AltovaXML Tools或XQSharp运行)
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="2.0">
<xsl:param name="locale" select="'ES'"/>
<xsl:key name="k1"
match="Localizations/Localization[Locale = $locale]//*[Id]"
use="Id"/>
<xsl:key name="k2"
match="Localizations/Localization[Locale = $locale]//*[not(Id) and not(*)]"
use="local-name()"/>
<xsl:template match="Page/Content//*[not(Id) and *]">
<xsl:copy>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
<xsl:template match="Page">
<xsl:copy>
<xsl:copy-of select="Id"/>
<xsl:apply-templates select="Content"/>
</xsl:copy>
</xsl:template>
<xsl:template match="Page//*[Id]">
<xsl:variable name="loc" select="key('k1', Id)"/>
<xsl:choose>
<xsl:when test="$loc">
<xsl:copy-of select="$loc"/>
</xsl:when>
<xsl:otherwise>
<xsl:copy-of select="."/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
<xsl:template match="Page//*[not(Id) and not(*)]">
<xsl:variable name="loc" select="key('k2', local-name())"/>
<xsl:choose>
<xsl:when test="$loc">
<xsl:copy-of select="$loc"/>
</xsl:when>
<xsl:otherwise>
<xsl:copy>
<xsl:apply-templates/>
</xsl:copy>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>但我不确定该样式表是否清楚地陈述和实现了您的需求。
