xslt, как объединить узлы продукта

Question

Мне нужно объединить магазин товаров, который содержит размер в названии. Как вы можете видеть, я должен вырезать размер из названия продукта и поместить его в новый элемент внутри группового элемента «РАЗМЕРЫ», то же самое с PARTNO и STOCK, которые необходимы для идентификации продукта, его размеров и количества. Я создал xslt с шаблоном и циклом foreach, но я не знаю, как проверить, был ли создан какой-то узел ранее.

Это очень важно для меня, потому что xslt - это моя новая ответственность в моей работе, я новичок в xslt, поэтому мой код очень прост и безобразен.

вот пример xml:

    <?xml version="1.0" encoding="Windows-1250"?>
    <SHOP xmlns="http://www.b2b.abisaltest.pl">
       <SHOPITEM>
          <PRODUCT>ZBRS180 CZERWONA BRAMKA PIŁKARSKA</PRODUCT>
          <PRICE>167.01</PRICE>
          <PARTNO>5907695527654</PARTNO>
          <STOCK>177</STOCK>
       </SHOPITEM>
       <SHOPITEM>
          <PRODUCT>NJ2117 A NIEBIESKO-RÓŻOWE SIZE. M (34-37)  ŁYŻWOROLKI NILS 
           EXTREME</PRODUCT>
          <PRICE>113.01</PRICE>
          <PARTNO>5907695510333</PARTNO>
          <STOCK>158</STOCK>
       </SHOPITEM>
       <SHOPITEM>
          <PRODUCT>NJ2117 A NIEBIESKO-RÓŻOWE SIZE. L (38-41)  ŁYŻWOROLKI NILS 
          EXTREME</PRODUCT>
          <PRICE>113.01</PRICE>
          <PARTNO>5907695510334</PARTNO>
          <STOCK>35</STOCK>
       </SHOPITEM>
    </SHOP>

**Output file should looks like that:**

    <?xml version="1.0" encoding="Windows-1250"?>
    <SHOP>
       <SHOPITEM>
          <PRODUCT>ZBRS180 CZERWONA BRAMKA PIŁKARSKA</PRODUCT>
          <PRICE>167.01</PRICE>
          <PARTNO>5907695527654</PARTNO>
          <STOCK>177</STOCK>
       </SHOPITEM>
       <SHOPITEM>
          <PRODUCT>NJ2117 A NIEBIESKO-RÓŻOWE ŁYŻWOROLKI NILS EXTREME</PRODUCT>
          <SIZES>
             <SIZE>M (34-37)</SIZE>
             <SIZE>L (38-41)</SIZE>
          </SIZES>
          <PARTNOS>
            <PARTNO>5907695510333</PARTNO>
            <PARTNO>5907695510334</PARTNO>
          </PARTNOS>
          <STOCKS>
            <STOCK>158</STOCK>
            <STOCK>35</STOCK>
          </STOCKS>
          <PRICE>113.01</PRICE>
       </SHOPITEM>
</SHOP>

Answer 1

Это не совсем просто - но я думаю, что это может быть намного проще, чем то, что вы пытаетесь сделать:

XSLT 1.0

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:abi="http://www.b2b.abisaltest.pl"
exclude-result-prefixes="abi">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>

<xsl:key name="item" match="abi:SHOPITEM" use="substring-before(abi:PRODUCT, ' ')" />

<xsl:template match="/abi:SHOP">
    <SHOP>
        <!-- MUENCHIAN GROUPING -->
        <xsl:for-each select="abi:SHOPITEM[count(. | key('item', substring-before(abi:PRODUCT, ' '))[1]) = 1]">
            <xsl:variable name="current-group" select="key('item', substring-before(abi:PRODUCT, ' '))" />
            <xsl:choose>
                <xsl:when test="count($current-group) > 1">
                    <SHOPITEM>
                        <PRODUCT>
                            <xsl:value-of select="substring-before(abi:PRODUCT, 'SIZE.')"/>
                            <xsl:value-of select="substring-after(substring-after(abi:PRODUCT, 'SIZE. '), ')')"/>

                            <xsl:for-each select="$current-group">
                                <SIZE>
                                    <xsl:value-of select="substring-before(substring-after(abi:PRODUCT, 'SIZE. '), ')')"/>
                                    <xsl:text>)</xsl:text>
                                </SIZE>
                            </xsl:for-each>
                        </SIZES>
                        <PARTNOS>
                            <xsl:apply-templates select="$current-group/abi:PARTNO"/>
                        </PARTNOS>
                        <STOCKS>
                            <xsl:apply-templates select="$current-group/abi:STOCK"/>

                </xsl:when>
                <xsl:otherwise>
                    <xsl:apply-templates select="$current-group"/>
                </xsl:otherwise>
            </xsl:choose>
        </xsl:for-each>
    </SHOP>
</xsl:template>

<xsl:template match="abi:*">
    <xsl:element name="{local-name()}">
        <xsl:apply-templates/>
     </xsl:element>
</xsl:template>

</xsl:stylesheet>

Answer 2

Вы можете попробовать это:

<xsl:transform version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
xmlns:abi="http://www.b2b.abisaltest.pl"
