我有一个具有抽象模式的schematron文件,我想使用xsl文件将此文件转换为没有抽象模式的文件,所有抽象模式都是实例。
问题是当我实例化抽象模式时,如果我在<pattern>
中提供@id属性一切正常。没有@id,抽象模式中的paremeter无法正确替换
schematron文件如下
<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://purl.oclc.org/dsdl/schematron">
<title>Table abstract patterns</title>
<pattern abstract="true" id="table">
<rule context="$table">
<assert test="$row">A table has at least one row</assert>
</rule>
<rule context="$row">
<assert test="$cell">A table row has at least one cell</assert>
</rule>
</pattern>
<pattern is-a="table">
<param name="table" value="table"/>
<param name="row" value="tr"/>
<param name="cell" value="td"/>
</pattern>
</schema>
xsl文件是

Abstract patterns allow you to say, for example
<pattern name="htmlTable" is-a="table">
<param name="row" value="html:tr"/>
<param name="cell" value="html:td" />
<param name="table" value="html:table" />
</pattern>
For a good introduction, see Uche Ogbujii's article for IBM DeveloperWorks
"Discover the flexibility of Schematron abstract patterns"
http://www-128.ibm.com/developerworks/xml/library/x-stron.html
However, note that ISO Schematron uses @name and @value attributes on
the iso:param element, and @id not @name on the pattern element.

我的预期结果是
<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://purl.oclc.org/dsdl/schematron">
<title>Table abstract patterns</title>
<pattern id="table1">
<rule context="table">
<assert test="tr">A table has at least one row</assert>
</rule>
<rule context="tr">
<assert test="td">A table row has at least one cell</assert>
</rule>
</pattern>
</schema>
现在我有一个预处理xsl如下,如果我先使用这个,然后再使用上面的那个,我会得到我想要的东西
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xslt="http://www.w3.org/1999/XSL/Transform"
version="1.0"

xmlns:nvdl="http://purl.oclc.org/dsdl/nvdl"
xmlns:iae="http://www.schematron.com/namespace/iae"
>
<xsl:template match="node() | @*">
<xsl:copy>
<xsl:apply-templates select="node() | @*" />
</xsl:copy>
</xsl:template>
<xsl:template match="iso:pattern[not(@id)]">
<xslt:comment>Add @id for pattern </xslt:comment>
<xsl:copy>
<xslt:comment>Add @id for pattern </xslt:comment>
<xsl:attribute name="id">
<xslt:value-of select="generate-id(.) "/>
</xsl:attribute>
<xsl:apply-templates select="node() | @*"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
如何将这两个文件组合在一起?
答案 0 :(得分:0)
使用以下命令更改模板:
<xslt:template name="iae:abstract-to-real" >
<xslt:param name="caller"/>
<xslt:param name="is-a" />
<xslt:for-each select="//iso:pattern[@id= $is-a]">
<xslt:copy>
<xslt:choose>
<xslt:when test=" string-length( $caller ) = 0">
<xslt:attribute name="id"><xslt:value-of select="concat( generate-id(.) , $is-a)"/></xslt:attribute>
</xslt:when>
<xslt:otherwise>
<xslt:attribute name="id"><xslt:value-of select="$caller" /></xslt:attribute>
</xslt:otherwise>
</xslt:choose>
<xslt:apply-templates select="*|text()" mode="iae:do-pattern" >
<xslt:with-param name="caller"><xslt:value-of select="$caller"/></xslt:with-param>
</xslt:apply-templates>
</xslt:copy>
</xslt:for-each>
<xslt:for-each select="//iso:pattern[not(@id)]">
<xslt:copy>
<xslt:choose>
<xslt:when test=" string-length( $caller ) = 0"/>
<xslt:otherwise>
<xslt:attribute name="id"><xslt:value-of select="$caller" /></xslt:attribute>
</xslt:otherwise>
</xslt:choose>
<xslt:apply-templates select="*|text()" mode="iae:do-pattern" >
<xslt:with-param name="caller"><xslt:value-of select="$caller"/></xslt:with-param>
</xslt:apply-templates>
</xslt:copy>
</xslt:for-each>
</xslt:template>
