问题描述
我想使用 XSLT 转换一些 xmi 文件.一切正常，但我不明白为什么我的模板packagedElement"复制了 标签值Version 1.0"和EAUML Version:1.0"(见输出).>
xmi 文件:
<xmi:XMI xmi:version="2.1" xmlns:uml="http://schema.omg.org/spec/UML/2.1" xmlns:xmi="http://schema.omg.org/spec/XMI/2.1" xmlns:thecustomprofile="http://www.sparxsystems.com/profiles/thecustomprofile/1.0" xmlns:EAUML="http://www.sparxsystems.com/profiles/EAUML/1.0"><uml:Model xmi:type="uml:Model" name="EA_Model"visibility="public"><packagedElement xmi:type="uml:Package" name="Test"visibility="public">...</packagedElement></uml:模型><xmi:扩展><个人资料><uml:Profile xmi:version="2.1" xmlns:uml="http://schema.omg.org/spec/UML/2.1/" xmlns:xmi="http://schema.omg.org/spec/XMI/2.1" xmi:id="thecustomprofile" nsPrefix="thecustomprofile" name="thecustomprofile" metamodelReference="mmref01"><ownedComment xmi:type="uml:Comment" xmi:id="comment01" annotatedElement="thecustomprofile"><身体>版本:1.0</ownedComment><packagedElement xmi:type="uml:Stereotype" xmi:id="enum" name="enum"/>...</uml:个人资料><uml:Profile xmi:version="2.1" xmlns:uml="http://schema.omg.org/spec/UML/2.1/" xmlns:xmi="http://schema.omg.org/spec/XMI/2.1" xmi:id="8C9E6706-8" nsPrefix="EAUML" name="EAUML" metamodelReference="mmref01"><ownedComment xmi:type="uml:Comment" xmi:id="comment01" annotatedElement="8C9E6706-8"><body>EAUML 版本:1.0</body></ownedComment>...</uml:个人资料></个人资料></xmi:扩展></xmi:XMI>XSLT 文件(

你看到的是 内置模板规则 应用于未与您的任何模板显式匹配的节点.
要解决此问题，请添加一个模板以防止默认情况下复制文本节点:
或者 - 最好，恕我直言 - 更有选择性地应用模板.
I want to transform some xmi files using XSLT. Everything works fine, but I do not understand why the <body> tag values "Version 1.0" and "EAUML Version:1.0" are copied by my template "packagedElement" (see output).
xmi File:
<?xml version="1.0" encoding="windows-1252"?>
<xmi:XMI xmi:version="2.1" xmlns:uml="http://schema.omg.org/spec/UML/2.1" xmlns:xmi="http://schema.omg.org/spec/XMI/2.1" xmlns:thecustomprofile="http://www.sparxsystems.com/profiles/thecustomprofile/1.0" xmlns:EAUML="http://www.sparxsystems.com/profiles/EAUML/1.0">
<uml:Model xmi:type="uml:Model" name="EA_Model" visibility="public">
<packagedElement xmi:type="uml:Package" name="Test" visibility="public">
...
</packagedElement>
</uml:Model>
<xmi:Extension>
<profiles>
<uml:Profile xmi:version="2.1" xmlns:uml="http://schema.omg.org/spec/UML/2.1/" xmlns:xmi="http://schema.omg.org/spec/XMI/2.1" xmi:id="thecustomprofile" nsPrefix="thecustomprofile" name="thecustomprofile" metamodelReference="mmref01">
<ownedComment xmi:type="uml:Comment" xmi:id="comment01" annotatedElement="thecustomprofile">
<body> Version:1.0</body>
</ownedComment>
<packagedElement xmi:type="uml:Stereotype" xmi:id="enum" name="enum"/>
...
</uml:Profile>
<uml:Profile xmi:version="2.1" xmlns:uml="http://schema.omg.org/spec/UML/2.1/" xmlns:xmi="http://schema.omg.org/spec/XMI/2.1" xmi:id="8C9E6706-8" nsPrefix="EAUML" name="EAUML" metamodelReference="mmref01">
<ownedComment xmi:type="uml:Comment" xmi:id="comment01" annotatedElement="8C9E6706-8">
<body>EAUML Version:1.0</body>
</ownedComment>
...
</uml:Profile>
</profiles>
</xmi:Extension>
</xmi:XMI>
XSLT file (code inside <xsl:if> is irrelevant for my problem):
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xmi="http://schema.omg.org/spec/XMI/2.1"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:uml="http://www.omg.org/spec/UML/20131001"
xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore">
<xsl:strip-space elements="*"/>
<xsl:output indent="yes"/>
<xsl:template match="/">
<ecore:EPackage>
<xsl:apply-templates mode="packagedElement" />
</ecore:EPackage>
</xsl:template>
<xsl:template match="packagedElement" mode="packagedElement">
<xsl:if test="(@xmi:type='uml:Package')">
</xsl:if>
</xsl:template>
</xsl:stylesheet>
output:
<?xml version="1.0"?>
<ecore:EPackage xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore" xmlns:xmi="http://schema.omg.org/spec/XMI/2.1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:uml="http://www.omg.org/spec/UML/20131001"> Version:1.0 EAUML Version:1.0 </ecore:EPackage>
解决方案
What you see is the result of the built-in template rules being applied to nodes that aren't matched explicitly by any one of your templates.
To solve this, either add a template preventing text nodes being copied by default:
<xsl:template match="text()" mode="packagedElement"/>
or - preferably, IMHO - apply templates more selectively.
