XSLT . 使用xsl：param调用另一个模板

提问于

我是xslt的新手，并尝试创建一个XSLT，我调用另一个模板，将param值传递给它但不知何故，空白值出现在目标模板的param变量中 .

这是简化的示例xml文件：

<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<TCXML xmlns="http://www.tcxml.org/Schemas/TCXMLSchema">
 <BOMWindow elemId="id62" revision_rule="id60" top_line="id2">

    <GSIdentity elemId="id1" label="a00pC7EtM1CZ7D"/>

</BOMWindow>

 <IMAN_Drawing elemId="id78" owning_site="id4" primary_object="#id21" secondary_object="#id25" user_data="">

    <GSIdentity elemId="id50" label="R8D9sTvgBT4jNA"/>

</IMAN_Drawing>
  <IMAN_Drawing elemId="id79" owning_site="#id4" primary_object="#id22" secondary_object="#id26" user_data="">

    <GSIdentity elemId="id56" label="R8D9sTfVBT4jNA"/>

</IMAN_Drawing>
  <IMAN_Drawing elemId="id80" owning_site="#id4" primary_object="#id20" secondary_object="#id24" user_data="">

    <GSIdentity elemId="id44" label="R8A9sTu6BT4jNA"/>

</IMAN_Drawing>



<UGPART creation_date="2012-06-05T09:25:30Z" date_released="2012-06-05T09:25:33Z" ead_paragraph="" elemId="id117" format_used="PART" gov_classification="" object_name="Test"  owning_organization=""  >

    <GSIdentity elemId="id21" label="RXM9sPifBT4jNA"/>

</UGPART>
 <UGPART creation_date="2012-06-05T09:25:30Z" date_released="2012-06-05T09:25:33Z" ead_paragraph="" elemId="id117" format_used="PART" gov_classification="" object_name="Test2"  owning_organization=""  >

    <GSIdentity elemId="id20" label="R3K9sPifBT4jNA"/>

</UGPART>
 <UGPART creation_date="2012-06-05T09:25:30Z" date_released="2012-06-05T09:25:33Z" ead_paragraph="" elemId="id117" format_used="PART" gov_classification="" object_name="Test3"  owning_organization=""  >

    <GSIdentity elemId="id22" label="xuO9sPifBT4jNA"/>

</UGPART>

在XML中，有3个IMAN_Drawing标记和3个UGPART标记

这是我的xslt

<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"  xmlns:plm="http://www.tcxml.org/Schemas/TCXMLSchema" version="1.0">
  <xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>
<xsl:template match="/plm:TCXML/plm:IMAN_Drawing">  
<xsl:copy>
    <xsl:copy-of select="@*" />
    <xsl:for-each select="/plm:TCXML/plm:IMAN_Drawing">
        <xsl:variable name="currentSecObjectId" select="@secondary_object"/>
        <xsl:variable name="RefSecObjectId" select="substring($currentSecObjectId,2)"/>
        <xsl:variable name="currentPrimaryObjectId" select="/plm:TCXML/plm:IMAN_Drawing/@primary_object"/>
        <xsl:variable name="RefPrimaryObjectId" select="substring($currentPrimaryObjectId,2)"/>
        <xsl:call-template name="UGPart">
            <xsl:with-param name="PriId" select="$RefPrimaryObjectId"/>
        </xsl:call-template>
    </xsl:for-each>

    <xsl:apply-templates/>  

</xsl:copy> 
</xsl:template> 
    <xsl:template match="/plm:TCXML/plm:UGPART" name="UGPart">
    <xsl:param name="PriId"/>
    <xsl:copy>
    <xsl:if test="@object_name="'Test'">
        <xsl:attribute name="owning_organization">
            <xsl:value-of select="$PriId"/>
        </xsl:attribute>        
    </xsl:if>
      <xsl:copy-of select="@*[not(name()='owning_organization')]" /> 
    <xsl:apply-templates /> 
    </xsl:copy>

</xsl:template>
</xsl:stylesheet>

但输出是：owning_organization =“”

预期的结果是：当@object_name =“'Test'”时，它应该更新我从模板1传递的owning_organization属性，其值为= $ RefPrimaryObjectId for UGPART

这里出了什么问题？为什么$ RefPrimaryObjectId“值不会到达第二个模板 .

    你应该真的提供你期望的输出，否则很难理解你想要的 . 我根据您提供的样式表对您的预期输出进行了一些猜测 .

    我的意思是没有不尊重，我只是想提供帮助，但你的样式表指出了很多误解，而不是仅仅选择我的解决方案（下面提供），从长远来看，你可能会因为放下笔而变得更好并通过一些已发表的教程或阅读书籍 .

    无论如何......

    这个样式表......

    <?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:plm="http://www.tcxml.org/Schemas/TCXMLSchema" >
<xsl:output method="xml" indent="yes"/>

<xsl:template match="@*|node()">
 <xsl:copy>
  <xsl:apply-templates select="@*|node()"/>
 </xsl:copy>
</xsl:template>

<xsl:template match="plm:IMAN_Drawing">
 <xsl:variable name="id" select="substring(@primary_object,2)" /> 
 <xsl:copy>
  <xsl:apply-templates select="@*"/>
 </xsl:copy>
  <xsl:for-each select="../plm:UGPART[plm:GSIdentity/@elemId=$id]" >
   <xsl:copy>
     <xsl:apply-templates select="@*[name()!='owning_organization' or ../@object_name!='Test']"/>
     <xsl:if test="@object_name='Test'">
      <xsl:attribute name="owning_organization"><xsl:value-of select="$id" /></xsl:attribute>
    </xsl:if>  
    <xsl:apply-templates select="node()"/>
   </xsl:copy>
 </xsl:for-each>  
</xsl:template >

<xsl:template match="plm:UGPART" />

</xsl:stylesheet>

    ...当应用于您的样本输入时，将产生输出...

    <?xml version="1.0" encoding="utf-8"?>
<TCXML xmlns="http://www.tcxml.org/Schemas/TCXMLSchema">
 <BOMWindow elemId="id62" revision_rule="#id60" top_line="#id2">
    <GSIdentity elemId="id1" label="a00pC7EtM1CZ7D" />
</BOMWindow>
 <IMAN_Drawing elemId="id78" owning_site="#id4" primary_object="#id21" secondary_object="#id25" user_data="" /><UGPART creation_date="2012-06-05T09:25:30Z" date_released="2012-06-05T09:25:33Z" ead_paragraph="" elemId="id117" format_used="PART" gov_classification="" object_name="Test" owning_organization="id21">
    <GSIdentity elemId="id21" label="RXM9sPifBT4jNA" />
</UGPART>
  <IMAN_Drawing elemId="id79" owning_site="#id4" primary_object="#id22" secondary_object="#id26" user_data="" /><UGPART creation_date="2012-06-05T09:25:30Z" date_released="2012-06-05T09:25:33Z" ead_paragraph="" elemId="id117" format_used="PART" gov_classification="" object_name="Test3" owning_organization="">
    <GSIdentity elemId="id22" label="xuO9sPifBT4jNA" />
  </UGPART>
  <IMAN_Drawing elemId="id80" owning_site="#id4" primary_object="#id20" secondary_object="#id24" user_data="" /><UGPART creation_date="2012-06-05T09:25:30Z" date_released="2012-06-05T09:25:33Z" ead_paragraph="" elemId="id117" format_used="PART" gov_classification="" object_name="Test2" owning_organization="">
    <GSIdentity elemId="id20" label="R3K9sPifBT4jNA" />
</UGPART>
</TCXML>
