使用XSL将XMI转换为XML

Question

我正在尝试解析node中的xmi:type。但不能成功做到这一点。我附上了输入文件(uml - xmi格式)，我的xslt输入和我得到的输出(xml格式)。每当我看到"xmi:type = uml:OpaqueAction“时，我想修改输出来写一行。我可以访问同一行中的"name“，但不能访问xmi:type。不知道为什么

UML-XMI输入

XSLT输入

输出(.XML)

<?xml version="1.0" encoding="UTF-8"?>

Answer 1

这一行有一个问题：

<xsl:if test="@'xmi:type'='uml:OpaqueAction'">

正确的语法应该是：

<xsl:if test="@xmi:type='uml:OpaqueAction'">

您不需要在属性名称周围使用撇号。您只需要将它们包含在字符串周围即可。您还需要在XSLT中声明xmi名称空间，名称空间URI与XML中的名称空间URI相匹配。如果您已经尝试运行XSLT，这应该会在错误消息中突出显示。

实际上，在此之前会出现另一个错误，因为这些行是无效的

<xsl:template match="/UML:Model">
     <?xml version="1.0"?>

也许这只是您的问题的一个拼写错误，应该在XSLT的开头出现，但是如果您实际上试图在输出XML中包含xml声明，那么只需在xsl:output元素中将omit-xml-declaration更改为"no“即可。

试试这个XSLT

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns='uri:sadf'
 xmlns:UML="http://www.eclipse.org/uml2/4.0.0/UML" 
 xmlns:xmi="http://www.omg.org/spec/XMI/20110701"
 exclude-result-prefixes="UML xmi">
<xsl:output method="xml" omit-xml-declaration="no" encoding="UTF-8" indent="yes" />

<xsl:template match="/UML:Model">
    <sdf3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.0" type="fsmsadf" xsi:noNamespaceSchemaLocation="http://www.es.ele.tue.nl/sdf3/xsd/sdf3-fsmsadf.xsd">
    <applicationGraph name="g">
        <xsl:apply-templates />
    </applicationGraph>
</sdf3>
</xsl:template>

<xsl:template match="packagedElement">
    <fsmsadf>
    <scenariograph name="sg0" type="t">
        <xsl:apply-templates select="node" />
    </scenariograph>
    </fsmsadf>
</xsl:template>

<xsl:template match="node">
     <xsl:if test="@xmi:type='uml:OpaqueAction'">
         <actor name="{@name}" source="{@outgoing}" />
     </xsl:if>
</xsl:template>
</xsl:stylesheet>
