Question

我的XML包含这样的元素......

<root>
    <data>
        <data_item>
            <colours>White, Red, Light Blue</colours>
        </data_item>
    </data>
</root>

我需要将其转换为......

<Items>
    <item>
<custom_options>name=Options,type=multiple,required=0,price=0.0000,price_type=fixed,sku=,option_title=White|name=Options,type=multiple,required=0,price=0.0000,price_type=fixed,sku=,option_title=Red|name=Options,type=multiple,required=0,price=0.0000,price_type=fixed,sku=,option_title=Light Blue</custom_options>
    </item>
</Items>

根据分隔符创建递归模板以分割字符串：

<xsl:template name="splitter">
    <xsl:param name="remaining-string"/>
    <xsl:param name="pattern"/>
    <xsl:choose>
        <xsl:when test="contains($remaining-string,$pattern)">
            <split-item>
                <xsl:value-of select = "normalize-space(substring-before($remaining-string,$pattern))"/>
            </split-item>
            <xsl:call-template name="splitter">
                <xsl:with-param name="remaining-string"  select="substring-after($remaining-string,$pattern)"/>
                <xsl:with-param name="pattern"  select="$pattern"/>
            </xsl:call-template>
        </xsl:when>
        <xsl:otherwise>
            <split-item>
                <!-- normalize-space reduces a sequence of spaces to at most one space. Do your own stuff to format individual split item -->
                <xsl:value-of select = "normalize-space($remaining-string)"/>
            </split-item>
        </xsl:otherwise>
    </xsl:choose>
</xsl:template>

在节点上调用此模板，该节点包含由模式分隔的项目序列：

<xsl:template match="/">
    <xsl:variable name = "colors">
        <xsl:for-each select="root/data/data_item">
            <xsl:call-template name="splitter">
                <xsl:with-param name="remaining-string"  select="colours"/>
                <xsl:with-param name="pattern"  select="','"/>
            </xsl:call-template>
        </xsl:for-each>
    </xsl:variable>
    <!--Do your thing with the variable colors. I simply send it to the output stream. If you further want to iterate over the split items, make sure you convert the variable to a node-set-->
    <xsl:copy-of select = "$colors"/>
</xsl:template>
