使用XSLT连接相同类型的数据_Xslt

使用XSLT连接相同类型的数据

xslt

使用XSLT连接相同类型的数据,xslt,Xslt,我想用XSLT连接相同类型的所有数据。我有以下XML： <ZE1MARAM> <ZE1KONDM SEGMENT="1"> <VKORG>NL01</VKORG> <KONDART>VKP0</KONDART> <BEGINDATUM>99991231</BEGINDATUM> <EN

我想用XSLT连接相同类型的所有数据。我有以下XML：

<ZE1MARAM>
        <ZE1KONDM SEGMENT="1">
            <VKORG>NL01</VKORG>
            <KONDART>VKP0</KONDART>
            <BEGINDATUM>99991231</BEGINDATUM>
            <ENDDATUM>20120605</ENDDATUM>
            <KONDWERT>NL01</KONDWERT>
            <MENGE> 70.00</MENGE>
            <CURRENCY>EUR</CURRENCY>
        </ZE1KONDM>
        <ZE1KONDM SEGMENT="1">
            <VKORG>NLWS</VKORG>
            <KONDART>VKP0</KONDART>
            <BEGINDATUM>99991231</BEGINDATUM>
            <ENDDATUM>20120605</ENDDATUM>
            <KONDWERT>NLWS</KONDWERT>
            <MENGE> 70.00</MENGE>
            <CURRENCY>EUR</CURRENCY>
        </ZE1KONDM>
        <ZE1KONDM SEGMENT="1">
            <VKORG>NLWS</VKORG>
            <KONDART>VKA0</KONDART>
            <BEGINDATUM>99991231</BEGINDATUM>
            <ENDDATUM>20120605</ENDDATUM>
            <KONDWERT>NLWS</KONDWERT>
            <MENGE> 33.00</MENGE>

因此，结果xml中具有相同VKORG值的每个ZE1KONDM都必须附加到相同的元素。所以结果是这样的：

<result>
<prices value="NL01">
    <price type="VKP0">
        70.00
    </price>
</prices>
<prices value="NLWS">
    <price type="VKP0">
        70.00
    </price>
    <price type="VKA0">
        55.00
    </price>
</prices>

                    <xsl:key name="myKey" match="ZE1KONDM" use="normalize-space(VKORG)" />

                <xsl:for-each select="ZE1KONDM">

                    <xsl:choose>

                        <xsl:when test="KONDART='VKP0'">
                            <xsl:element name="prices">

                                <xsl:element name="price">
                                    <xsl:value-of select="key('myKey', normalize-space(VKORG))/MENGE"/>
                                </xsl:element>

                            </xsl:element>
                        </xsl:when>

                    </xsl:choose>

                </xsl:for-each>

我试着用钥匙工作，并做了类似的事情：

<result>
<prices value="NL01">
    <price type="VKP0">
        70.00
    </price>
</prices>
<prices value="NLWS">
    <price type="VKP0">
        70.00
    </price>
    <price type="VKA0">
        55.00
    </price>
</prices>

                    <xsl:key name="myKey" match="ZE1KONDM" use="normalize-space(VKORG)" />

                <xsl:for-each select="ZE1KONDM">

                    <xsl:choose>

                        <xsl:when test="KONDART='VKP0'">
                            <xsl:element name="prices">

                                <xsl:element name="price">
                                    <xsl:value-of select="key('myKey', normalize-space(VKORG))/MENGE"/>
                                </xsl:element>

                            </xsl:element>
                        </xsl:when>

                    </xsl:choose>

                </xsl:for-each>

但是它不起作用，因为它只需要一把钥匙

有一些方法可以用xslt解决这个问题？

可能有更好的方法，但请尝试以下方法：

请注意：Muenchian分组方法可能是最快的XSLT 1.0分组方法，因为它使用键。其他方法（例如比较同级值）的速度太慢（O（N^2）），这对于在大数据量上使用它们是禁止的

II。XSLT 2.0解决方案：

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output omit-xml-declaration="yes" indent="yes"/> <xsl:strip-space elements="*"/> <xsl:template match="/*"> <result> <xsl:for-each-group select="*" group-by="VKORG"> <prices value="{VKORG}"> <xsl:apply-templates select="current-group()"/> </prices> </xsl:for-each-group> </result> </xsl:template> <xsl:template match="ZE1KONDM"> <price type="{KONDART}"> <xsl:value-of select="MENGE"/> </price> </xsl:template> </xsl:stylesheet>

<result> <prices value="NL01"> <price type="VKP0">70.00</price> </prices> <prices value="NLWS"> <price type="VKP0">70.00</price> <price type="VKA0">33.00</price> </prices> </result>

将此转换应用于同一XML文档（如上）时，会产生相同的正确结果：

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output omit-xml-declaration="yes" indent="yes"/> <xsl:strip-space elements="*"/> <xsl:template match="/*"> <result> <xsl:for-each-group select="*" group-by="VKORG"> <prices value="{VKORG}"> <xsl:apply-templates select="current-group()"/> </prices> </xsl:for-each-group> </result> </xsl:template> <xsl:template match="ZE1KONDM"> <price type="{KONDART}"> <xsl:value-of select="MENGE"/> </price> </xsl:template> </xsl:stylesheet>

<result> <prices value="NL01"> <price type="VKP0">70.00</price> </prices> <prices value="NLWS"> <price type="VKP0">70.00</price> <price type="VKA0">33.00</price> </prices> </result>

正确使用和
group by
属性以及功能。
如果我有类似的列表。。。。。。。。。。。。。。。那么它就不起作用了你有什么解决办法吗？
