英文:
XSLT 3.0 Identity transform document collection?
问题
我有一个XSLT 3.0文件：
<xsl:stylesheet version="3.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:map="http://www.w3.org/2005/xpath-functions/map"
xmlns:n1="urn:hl7-org:v3">
<xsl:output indent="yes" method="xml" encoding="utf-8"/>
<xsl:param name="icd10Map" as="map(xs:string, xs:string)"
select="
map {
'1742': 'C502',
'55090': 'K409',
'8442': 'S8350',
'7172': 'M2332',
'36616': 'H251',
'4550': 'K648'
}"/>
<xsl:variable name="map-keys" select="map:keys($icd10Map)"/>
<xsl:mode on-no-match="shallow-copy"/>
<xsl:template match="n1:translation[@codeSystemName = 'ICD-9-CM']/@code">
<xsl:attribute name="code">
<xsl:value-of select="$icd10Map($map-keys[translate(normalize-space(current()), ' 	

.', '') = .])"/>
</xsl:attribute>
</xsl:template>
</xsl:stylesheet>
一个输入XML：
<?xml-stylesheet type="text/xsl" href="./Content/xsl/CDA.xsl"?>
<ClinicalDocument xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:hl7-org:v3 NIST_C32_schema/C32_CDA.xsd" xmlns="urn:hl7-org:v3" xmlns:sdtc="urn:hl7-org:sdtc">
<realmCode code="US" />
<typeId root="2.16.840.1.113883.1.3" extension="POCD_HD000040" />
<templateId root="2.16.840.1.113883.10.20.22.1.1" />
<!-- ...其他内容... -->
<component>
<structuredBody>
<component>
<section>
<!-- ...其他内容... -->
<entry>
<act moodCode="EVN" classCode="ACT">
<templateId root="2.16.840.1.113883.10.20.22.4.65" />
<!-- ...其他内容... -->
<value nullFlavor="OTH" type="CD">
<translation code="366.16" displayName="Nuclear sclerosis" codeSystem="2.16.840.1.113883.6.103" codeSystemName="ICD-9-CM" />
</value>
</act>
</entry>
</section>
</component>
</structuredBody>
</component>
</ClinicalDocument>
Oxygen中的转换场景只有一个文档没有问题：
<value nullFlavor="OTH" type="CD">
<translation code="H251"
displayName="Nuclear sclerosis"
codeSystem="2.16.840.1.113883.6.103"
codeSystemName="ICD-9-CM"/>
</value>
然而，XSLT 3.0中对于“collection”的标识转换似乎是这样的：
<xsl:variable name="inFile" as="node()*" select="collection('hl7.xml')"/>
<xsl:template match="/">
<xsl:text>

 ICD9 Target Transformation in the collection is: 
 </xsl:text>
<xsl:for-each select="$inFile//n1:translation[@codeSystemName = 'ICD-9-CM']/@code">
<xsl:value-of select="$icd10Map($map-keys[translate(normalize-space(current()), ' 	

.', '') = .])" separator=" , "/>
</xsl:for-each>
</xsl:template>
结果：
ICD9 Target Transformation in the collection is:
H251
H251
K648
K648
K409
K409
S8350
M2332
M2332
S8350
如果我将XSLT更改为：
<xsl:mode on-no-match="shallow-copy"/>
<xsl:variable name="inFile" as="node()*" select="collection('hl7.xml')"/>
<xsl:template match="n1:translation[@codeSystemName = 'ICD-9-CM']/@code">
<xsl:text>

 ICD9 Target Transformation in the collection is: 
 </xsl:text>
<xsl:for-each select="$inFile">
<xsl:attribute name="code">
<xsl:value-of select="$icd10Map($map-keys[translate(normalize-space(current()), ' 	

.', '') = .])" separator=" , "/>
</xsl:attribute>
</xsl:for-each>
</xsl:template>
看起来没有任何转换发生，仅仅是提取目录文件“hl7.xml”中的
URI列表。
我开发了一个Java应用程序，可以批量验证文档是否符合
XSD，进行转换（不使用collection()），最终将文档写入数据库。日志中包含了所期望的结果：
引擎实例化：com.fc.andante.sax.SAXValidateStreamTransformWrite
模式验证状态：文件在:/ml/Andante/data/data 上已根据模式文件:/ml/Andante/data/operation-transform.xsd 进行了验证。
用户 'auditor' 已于 2020-08-26T23:05:26.357431 验证了文件在:/ml/Andante/data/data 上。
*****************
事务状态：正在验证数据库写入器的身份...
事务状态：作为 'super' 的用户正在转换文档集...
事务状态：成功将文档 data/data/cataract.xml 转换并写入数据库，URI 为 '/xslt-transform/cataract.xml'。

Can anyone help to solve the XSLT 3.0 Collections transform issue?

# 答案1
**得分**: 1
我会使用一个全局参数
<xsl:param name="inFiles" as="document-node()*" select="collection('hl7.xml')"/>
然后通过一个命名模板开始处理
<xsl:template name="xsl:initial-template">
<xsl:for-each select="$inFiles">
<xsl:result-document href="/xslt-transform/{tokenize(document-uri(), '/')[last()]}">
<xsl:apply-templates/>
</xsl:result-document>
</xsl:for-each>
</xsl:template>
然后您可以从问题中“xsl:import”您的第一个XSLT示例，或者当然可以编辑它以插入我展示的代码。确保让Saxon从命名模板开始（Saxon的“-it”命令行选项；在oXygen中通过不提供源文档）。

I would use a global parameter
<xsl:param name="inFiles" as="document-node()*" select="collection('hl7.xml')"/>
and then start processing with a named template
<xsl:template name="xsl:initial-template">
<xsl:for-each select="$inFiles">
<xsl:result-document href="/xslt-transform/{tokenize(document-uri(), '/')[last()]}">
<xsl:apply-templates/>
</xsl:result-document>
</xsl:for-each>
</xsl:template>
Then you can `xsl:import` your first XSLT sample from the question or of course edit it to insert the code I have shown. Make sure you let Saxon start with the named template (`-it` command line option for Saxon; in oXygen by not providing a source document).
