Question

我有一个xml文件并使用xslt转换，我需要生成以下xml文件。

<root>
    <Entities>
        <Classifications>
            <classificatie UniqueID="1">
                <Name>standaard1</Name>
            </classificatie>
            <classificatie UniqueID="2">
                <Name>bdi</Name>
            </classificatie>
            <classificatie UniqueID="3">
                <Name>lokaal1</Name>
            </classificatie>
        </Classifications>
        <Categories>
            <categorie UniqueID="1" id="D0001" super-id="" volgnummer="">
                <Name>Beleid vast-/opstellen en Bestuur</Name>
            </categorie>
            <categorie UniqueID="2" id="D0002" super-id="" volgnummer="">
                <Name>Beleid uitvoeren</Name>
            </categorie>
            <categorie UniqueID="3" id="D0003" super-id="" volgnummer="">
                <Name>Beheer en Handhaving</Name>
            </categorie>
        </Categories>
    </Entities>
    <Relations>
        <Classification_Category ClassficationID="1" CategoryID="2" />
    </Relations>
</root>

使用xslt转换，我能够生成实体节点。要生成关系节点，我需要生成UniqueID。实体节点中元素的生成唯一ID不存在于原始xml文件中，而是使用XSL文件生成。为了在XSLT代码之后生成唯一id，使用..

<xsl:template match="classificatie">
    <xsl:variable name="vNum1">
        <xsl:number level="any" count="classificatie"/>
    </xsl:variable>
    <classificatie>
        <xsl:attribute name="UniqueID">
            <xsl:value-of select="$vNum1"/>
        </xsl:attribute>
        <Name>
            <xsl:value-of select="@id"/>
        </Name>
    </classificatie>
</xsl:template>

对于Categorie，XLST模板类似于classificate模板。在原始XML文件中，类别节点嵌套在classificatie元素下。

在新生成的XML中，我需要在entieties元素下创建单独的元素。并且这些之间的关系需要在“关系”元素下建立。

我能够将节点生成为实体下的单独节点。并且我无法使用新生成的ID在“关系”节点下生成元素。

简而言之：使用非嵌套元素转换父子关系（嵌套关系）。 -Rajesh

此样式表：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:template match="root">
        <root>
            <Entities>
                <Classifications>
                    <xsl:apply-templates select="*/*"/>
                </Classifications>
                <Categories>
                    <xsl:apply-templates select="*/*/*/*"/>

            </Relations>
        </root>
    </xsl:template>
    <xsl:template match="classificatie">

            </name>
        </classificatie>
    </xsl:template>
    <xsl:template match="categorie">
