Question

有人能举例说明如何将以下XML节点与XSLT合并吗？

<pre>
    <Table1>
        <VendorID>123456</VendorID>
        <VendorName>StackOverflow Inc</VendorName>
        <Type>ADDRESS</Type>
        <TypeName>Mailing</TypeName>
        <DescriptionType>Main Mailing</DescriptionType>
        <Description>P O Box 01 Manama Bahrain</Description>
        <Online>0</Online>
        <CommodityTypeDesc/>
    </Table1>
</pre>

<pre>
    <Table1>
        <VendorID>123456</VendorID>
        <VendorName>StackOverflow Inc</VendorName>
        <Type>ADDRESS</Type>
        <TypeName>Remittance</TypeName>
        <DescriptionType>Main Remittance</DescriptionType>
        <Description>P O Box 02 Manama Bahrain</Description>
        <Online>0</Online>
        <CommodityTypeDesc/>
    </Table1>
</pre>

生成的XML需要将不同的地址节点分组到供应商的一个父节点中。

您还可以告诉我您使用哪种XSLT / XML工具。

Answer 1

VendorID下面的样式表组。请注意，您没有说明哪些元素是地址的一部分，哪些不是。此样式表假定只有VendorID和VendorName不属于该地址。相应地编辑。

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:key name="byVendor" match="root/pre" use="Table1/VendorID" />
    <xsl:template match="@*|node()" name="identity">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()" />
        </xsl:copy>
    </xsl:template>
    <xsl:template match="root/pre" />
    <xsl:template
        match="root/pre[generate-id() =
                        generate-id(key('byVendor', Table1/VendorID))]">
        <xsl:call-template name="identity"/>
    </xsl:template>
    <xsl:template match="Table1">
        <xsl:copy>
            <xsl:apply-templates select="@*|VendorID|VendorName" />
            <Addresses>
                <xsl:apply-templates select="key('byVendor', VendorID)/Table1"
                                       mode="address" />
            </Addresses>
        </xsl:copy>
    </xsl:template>
    <xsl:template match="Table1" mode="address">
        <Address>
            <xsl:apply-templates 
                 select="*[not(self::VendorID or self::VendorName)]" />
        </Address>
    </xsl:template>
</xsl:stylesheet>

应用于此输入时：

<root>
    <pre>
        <Table1>
            <VendorID>123456</VendorID>
            <VendorName>StackOverflow Inc</VendorName>
            <Type>ADDRESS</Type>
            <TypeName>Mailing</TypeName>
            <DescriptionType>Main Mailing</DescriptionType>
            <Description>P O Box 01 Manama Bahrain</Description>
            <Online>0</Online>
            <CommodityTypeDesc />
        </Table1>
    </pre>
    <pre>
        <Table1>
            <VendorID>123456</VendorID>
            <VendorName>StackOverflow Inc</VendorName>
            <Type>ADDRESS</Type>
            <TypeName>Remittance</TypeName>
            <DescriptionType>Main Remittance</DescriptionType>
            <Description>P O Box 02 Manama Bahrain</Description>
            <Online>0</Online>
            <CommodityTypeDesc />
        </Table1>
    </pre>
</root>

产地：

<root>
    <pre>
        <Table1>
            <VendorID>123456</VendorID>
            <VendorName>StackOverflow Inc</VendorName>
            <Addresses>
                <Address>
                    <Type>ADDRESS</Type>
                    <TypeName>Mailing</TypeName>
                    <DescriptionType>Main Mailing</DescriptionType>
                    <Description>P O Box 01 Manama Bahrain</Description>
                    <Online>0</Online>
                    <CommodityTypeDesc />
                </Address>
                <Address>
                    <Type>ADDRESS</Type>
                    <TypeName>Remittance</TypeName>
                    <DescriptionType>Main Remittance</DescriptionType>
                    <Description>P O Box 02 Manama Bahrain</Description>
                    <Online>0</Online>
                    <CommodityTypeDesc />
                </Address>
            </Addresses>
        </Table1>
    </pre>
</root>

Answer 2

XML实际上如下，因此我得到重复的原因：

<Vendors>
    <Table1>
        <VendorID>123456</VendorID>
        <VendorName>StackOverflow Inc</VendorName>
        <Type>ADDRESS</Type>
        <TypeName>Mailing</TypeName>
        <DescriptionType>Main Mailing</DescriptionType>
        <Description>P O Box 01 Manama Bahrain</Description>
        <Online>0</Online>
        <CommodityTypeDesc />
    </Table1>
    <Table1>
        <VendorID>123456</VendorID>
        <VendorName>StackOverflow Inc</VendorName>
        <Type>ADDRESS</Type>
        <TypeName>Remittance</TypeName>
        <DescriptionType>Main Remittance</DescriptionType>
        <Description>P O Box 02 Manama Bahrain</Description>
        <Online>0</Online>
        <CommodityTypeDesc />
    </Table1>
</Vendors>
