一个 xslt 转换的结果是另一个 xslt 转换的输入
Result of one xslt transformation is input for the another one
我是 xslt 的初学者，所以请不要介意我问一些基本问题。我想使用第一个转换级别的结果作为另一个转换级别的输入。第一个转换的输入是一个 target.xml 文件，其中包括订阅者（“aries”，“cas”...）：
<subscription-table>
<subscriber name="aries" useZipXfer="yes" usePubMed="no">
<ftp server="dummy.url1.com" port="21" remotedir="/XXXXXXX" userid="XXXXXXX" password="XXXXXXXXX" binary="yes" passive="no"/>
<notify-success>
<mail mailhost="smtprelayptc1.wkglobal.net" mailport="25" subject="MRCS-PS HEADER UPDATE - PAP">
<from address="success1.from@mail.com"/>
<to address="success1.to@mail.com"/>
</mail>
</notify-success>
<notify-failure>
<mail mailhost="smtprelayptc1.wkglobal.net" mailport="25" subject="MRCS-PS HEADER UPDATE - PAP">
<from address="failure1.from@mail.com"/>
<to address="failure1.to@mail.com"/>
</mail>
</notify-failure>
</subscriber>
<subscriber name="cas" useZipXfer="no" usePubMed="yes" sendPromote="no">
<ftp server="dummy.url2.com" port="21" remotedir="/YYYYYYY" userid="YYYYYYY" password="YYYYYYYYY" binary="yes" passive="no"/>
<notify-success>
<mail mailhost="smtprelayptc1.wkglobal.net" mailport="25" subject="MRCS-PS HEADER UPDATE - PAP">
<from address="success2.from@mail.com"/>
<to address="success2.to@mail.com"/>
</mail>
</notify-success>
<notify-failure>
<mail mailhost="smtprelayptc1.wkglobal.net" mailport="25" subject="MRCS-PS HEADER UPDATE - PAP">
<from address="failure2.from@mail.com"/>
<to address="failure2.to@mail.com"/>
</mail>
</notify-failure>
</subscriber>
</subscription-table>
每个订阅者都有自己的文件（aries_subscriptions.xml、cas_subscriptions.xml...）。订阅文件包括期刊。例如，aries_subscriptions.xml 是：
<subscription>
<database status="update" name="ovftdb">
<journal status="*" name="00002030" >
<issue status="new" pubdate="01/01/2004" name="*" an="99999999-999999999-99999" >
<header/>
</issue>
</journal>
<journal status="*" name="00000374" >
<issue status="new" pubdate="01/01/2004" name="*" an="99999999-999999999-99999" >
<header/>
</issue>
</journal>
<journal status="*" name="00000372" >
<issue status="new" pubdate="01/01/2004" name="*" an="99999999-999999999-99999" >
<header/>
</issue>
</journal>
...
我需要生成第三个文件，lookup.xml，它可以有重复的日志，取决于订阅者（订阅者在属性“标识符”中）：
<?xml version="1.0" encoding="UTF-8"?>
<journals xmlns:xlink="http://www.w3.org/1999/xlink">
<journal name="00002030">
<target identifier="aries" pubdate="01/01/2004">
<targetLink xmlns:xlink="http://www.w3.org/1999/xlink"
xlink:href="targets.xml#xpointer(/descendant::subscriber[attribute::name='$subscriberNameFromDoc'])"/>
</target>
</journal>
<journal name="00000372">
<target identifier="aries" pubdate="01/01/2004">
<targetLink xmlns:xlink="http://www.w3.org/1999/xlink"
xlink:href="targets.xml#xpointer(/descendant::subscriber[attribute::name='$subscriberNameFromDoc'])"/>
</target>
</journal>
<journal name="00002030">
<target identifier="cas" pubdate="01/01/2004">
<targetLink xmlns:xlink="http://www.w3.org/1999/xlink"
xlink:href="targets.xml#xpointer(/descendant::subscriber[attribute::name='$subscriberNameFromDoc'])"/>
</target>
</journal>
<journal name="00000372">
<target identifier="cas" pubdate="01/01/2004">
<targetLink xmlns:xlink="http://www.w3.org/1999/xlink"
xlink:href="targets.xml#xpointer(/descendant::subscriber[attribute::name='$subscriberNameFromDoc'])"/>
</target>
</journal>
</journals>
我想使用 xslt 代码，它创建重复的日志，并生成具有唯一日志及其所有嵌套订阅者的文档。所需文件为：
<?xml version="1.0" encoding="UTF-8"?>
<journals xmlns:xlink="http://www.w3.org/1999/xlink"
<journal name="00002030">
<target identifier="aries" pubdate="01/01/2004">
<targetLink xmlns:xlink="http://www.w3.org/1999/xlink"
xlink:href="targets.xml#xpointer(/descendant::subscriber[attribute::name='$subscriberNameFromDoc'])"/>
</target>
<target identifier="cas" pubdate="01/01/2004">
<targetLink xmlns:xlink="http://www.w3.org/1999/xlink"
xlink:href="targets.xml#xpointer(/descendant::subscriber[attribute::name='$subscriberNameFromDoc'])"/>
</target>
</journal>
<journal name="00000372">
<target identifier="aries" pubdate="01/01/2004">
<targetLink xmlns:xlink="http://www.w3.org/1999/xlink"
xlink:href="targets.xml#xpointer(/descendant::subscriber[attribute::name='$subscriberNameFromDoc'])"/>
</target>
<target identifier="cas" pubdate="01/01/2004">
<targetLink xmlns:xlink="http://www.w3.org/1999/xlink"
xlink:href="targets.xml#xpointer(/descendant::subscriber[attribute::name='$subscriberNameFromDoc'])"/>
</target>
</journal>
</journals>
创建重复日志的 xslt 的第一部分是：
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

<xsl:with-param name="char" select="'/'" />
</xsl:call-template>
</xsl:variable>
<xsl:variable name="inputFolderPath"

<xsl:variable name="inputFile"

<xsl:variable name="tokens"

<xsl:template match="@* | * | comment() | processing-instruction()">

</xsl:template>
<xsl:template match="text()" mode="package">

<xsl:template match="/" mode="package">

<xsl:apply-templates select="$initialOutput" mode="remove-duplicates"/>
</xsl:result-document>
</xsl:template>
<xsl:template match="subscriber" mode="package">
<xsl:variable name="subscriberName" select="document(concat($inputFolderPath, '/', @name,'_subscriptions.xml'))" />
<xsl:element name="journals" namespace="http://www.w3.org/1999/xlink">
<xsl:apply-templates select="$subscriberName" mode="journal-processing"/>
</xsl:element>
</xsl:template>
<xsl:template match="journal" mode="journal-processing">
<xsl:variable name="journalName" select="@name" />
<xsl:variable name="journalPubDate" select="issue/@pubdate" />
<xsl:variable name="subscriberNameFromDoc" select="substring-before(tokenize(base-uri(), '/')[last()], '_subscriptions')" />
<xsl:element name="journal">
<xsl:attribute name="name" select="$journalName"/>
<xsl:element name="target">
<xsl:attribute name="identifier" select="$subscriberNameFromDoc"/>
<xsl:attribute name="pubdate" select="$journalPubDate"/>
<xsl:element name="targetLink">
<xsl:attribute name="xlink:href">targets.xml#xpointer(/descendant::subscriber[attribute::name='$subscriberNameFromDoc'])</xsl:attribute>
<xsl:attribute name="xlink:href" select="targets.xml#//descendant::subscriber[attribute::name='$subscriberNameFromDoc']"/> -->
</xsl:element>
</xsl:element>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
我想使用 $initialOutput 变量将第一个转换的结果提供给下一个。在第二次转换中，assetTargetToLookupRemoveDuplicates.xsl，我有以下代码：
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"

exclude-result-prefixes="xlink xs xsl saxon"

<xsl:strip-space elements="*" />
<xsl:template match="/" mode="remove-duplicates">
<xsl:apply-templates select="journals" mode="remove-duplicates"/>
</xsl:template>
<xsl:template match="journals" mode="remove-duplicates">
<xsl:copy>
<xsl:for-each-group select="journal" group-by="@name">
<xsl:copy>
<xsl:copy-of select="@*"/>
<xsl:copy-of select="current-group()/target"/>
</xsl:copy>
</xsl:for-each-group>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
第二个转换不会将重复的日记帐转换为唯一的日记帐。整个过程的结果是具有重复期刊的文档。结果又是：
<?xml version="1.0" encoding="UTF-8"?>
<journals xmlns:xlink="http://www.w3.org/1999/xlink">
<journal name="00002030">
<target identifier="aries" pubdate="01/01/2004">
<targetLink xmlns:xlink="http://www.w3.org/1999/xlink"
xlink:href="targets.xml#xpointer(/descendant::subscriber[attribute::name='$subscriberNameFromDoc'])"/>
</target>
</journal>
<journal name="00000372">
<target identifier="aries" pubdate="01/01/2004">
<targetLink xmlns:xlink="http://www.w3.org/1999/xlink"

</target>
</journal>
<journal name="00002030">
<target identifier="cas" pubdate="01/01/2004">
<targetLink xmlns:xlink="http://www.w3.org/1999/xlink"
xlink:href="targets.xml#xpointer(/descendant::subscriber[attribute::name='$subscriberNameFromDoc'])"/>
</target>
</journal>
<journal name="00000372">
<target identifier="cas" pubdate="01/01/2004">
<targetLink xmlns:xlink="http://www.w3.org/1999/xlink"
xlink:href="targets.xml#xpointer(/descendant::subscriber[attribute::name='$subscriberNameFromDoc'])"/>
</target>
</journal>
</journals>
你能帮我找出为什么第二次转换会这样吗？提前感谢您的帮助。
我认为你需要重写
<xsl:template match="/" mode="package">
<xsl:result-document method="xml" omit-xml-declaration="no" indent="yes" encoding="UTF-8" href="lookup.xml">
<xsl:variable name="initialOutput">
<xsl:apply-templates mode="package"/>
</xsl:variable>
<xsl:apply-templates select="$initialOutput" mode="remove-duplicates"/>
</xsl:result-document>
</xsl:template>
作为
<xsl:variable name="initialOutput">
<xsl:apply-templates mode="package"/>
</xsl:variable>
<xsl:template match="/">
<xsl:result-document method="xml" omit-xml-declaration="no" indent="yes" encoding="UTF-8" href="lookup.xml">
<xsl:apply-templates select="$initialOutput" mode="remove-duplicates"/>
</xsl:result-document>
</xsl:template>
感谢 Martin 的评论和帮助，我终于解决了这个问题。以下代码执行我在问题中描述的内容：

我是 xslt 的初学者，所以请不要介意我问一些基本问题。我想使用第一个转换级别的结果作为另一个转换级别的输入。第一个转换的输入是一个 target.xml 文件，其中包括订阅者（“aries”，“cas”...）：
<subscription-table>
<subscriber name="aries" useZipXfer="yes" usePubMed="no">
<ftp server="dummy.url1.com" port="21" remotedir="/XXXXXXX" userid="XXXXXXX" password="XXXXXXXXX" binary="yes" passive="no"/>
<notify-success>
<mail mailhost="smtprelayptc1.wkglobal.net" mailport="25" subject="MRCS-PS HEADER UPDATE - PAP">
<from address="success1.from@mail.com"/>
<to address="success1.to@mail.com"/>
</mail>
</notify-success>
<notify-failure>
<mail mailhost="smtprelayptc1.wkglobal.net" mailport="25" subject="MRCS-PS HEADER UPDATE - PAP">
<from address="failure1.from@mail.com"/>
<to address="failure1.to@mail.com"/>
</mail>
</notify-failure>
</subscriber>
<subscriber name="cas" useZipXfer="no" usePubMed="yes" sendPromote="no">
<ftp server="dummy.url2.com" port="21" remotedir="/YYYYYYY" userid="YYYYYYY" password="YYYYYYYYY" binary="yes" passive="no"/>
<notify-success>
<mail mailhost="smtprelayptc1.wkglobal.net" mailport="25" subject="MRCS-PS HEADER UPDATE - PAP">
<from address="success2.from@mail.com"/>
<to address="success2.to@mail.com"/>
</mail>
</notify-success>
<notify-failure>
<mail mailhost="smtprelayptc1.wkglobal.net" mailport="25" subject="MRCS-PS HEADER UPDATE - PAP">
<from address="failure2.from@mail.com"/>
<to address="failure2.to@mail.com"/>
</mail>
</notify-failure>
</subscriber>
</subscription-table>
每个订阅者都有自己的文件（aries_subscriptions.xml、cas_subscriptions.xml...）。订阅文件包括期刊。例如，aries_subscriptions.xml 是：
<subscription>
<database status="update" name="ovftdb">
<journal status="*" name="00002030" >
<issue status="new" pubdate="01/01/2004" name="*" an="99999999-999999999-99999" >
<header/>
</issue>
</journal>
<journal status="*" name="00000374" >
<issue status="new" pubdate="01/01/2004" name="*" an="99999999-999999999-99999" >
<header/>
</issue>
</journal>
<journal status="*" name="00000372" >
<issue status="new" pubdate="01/01/2004" name="*" an="99999999-999999999-99999" >
<header/>
</issue>
</journal>
...
我需要生成第三个文件，lookup.xml，它可以有重复的日志，取决于订阅者（订阅者在属性“标识符”中）：
<?xml version="1.0" encoding="UTF-8"?>
<journals xmlns:xlink="http://www.w3.org/1999/xlink">

</target>
</journal>
<journal name="00000372">

</target>
</journal>
</journals>
我想使用 xslt 代码，它创建重复的日志，并生成具有唯一日志及其所有嵌套订阅者的文档。所需文件为：

创建重复日志的 xslt 的第一部分是：

我想使用 $initialOutput 变量将第一个转换的结果提供给下一个。在第二次转换中，assetTargetToLookupRemoveDuplicates.xsl，我有以下代码：

第二个转换不会将重复的日记帐转换为唯一的日记帐。整个过程的结果是具有重复期刊的文档。结果又是：

你能帮我找出为什么第二次转换会这样吗？提前感谢您的帮助。
我认为你需要重写
<xsl:template match="/" mode="package">
<xsl:result-document method="xml" omit-xml-declaration="no" indent="yes" encoding="UTF-8" href="lookup.xml">
<xsl:variable name="initialOutput">
<xsl:apply-templates mode="package"/>
</xsl:variable>
<xsl:apply-templates select="$initialOutput" mode="remove-duplicates"/>
</xsl:result-document>
</xsl:template>
作为
<xsl:variable name="initialOutput">
<xsl:apply-templates mode="package"/>
</xsl:variable>
<xsl:template match="/">
<xsl:result-document method="xml" omit-xml-declaration="no" indent="yes" encoding="UTF-8" href="lookup.xml">
<xsl:apply-templates select="$initialOutput" mode="remove-duplicates"/>
</xsl:result-document>
</xsl:template>
