数据块中的 XSLT 转换以根据条件获取值

XSLT Transformation in databricks to get the value based on condition

我是 XSL 编程的新手,正在尝试执行以下转换,我必须根据其他 attribute/tag

中的文本值获取值

来源XML:

XSLT 文件

    <xsl:template match="health-star-rating">
    <xsl:param name="text"/>
    <xsl:choose>
        <xsl:when test="contains($text,'DI/Claims')">
            <xsl:value-of select="$text" />
        </xsl:when>
    </xsl:choose>
    </xsl:template>
    <xsl:template match="/">

            </ActionType>

            </CreateDateTime>
            <Items>
                <Item>
                <HealthStarRating>
                        <xsl:value-of select="ns1:productSpecificationFullDTO/ns1:specificationSectionDetail/ns1:specificationSectionFoodOtherLabellingCopySection/ns1:claimOrStatement/ns1:packCopyText"/>
                </HealthStarRating>
                <HealthStarRatingDIClaims>
                        <xsl:value-of select="ns1:productSpecificationFullDTO/ns1:specificationSectionDetail/ns1:specificationSectionFoodOtherLabellingCopySection/ns1:claimOrStatement/ns1:packCopyText"/>
                </HealthStarRatingDIClaims>

            </Items>
        </ItemDetails>
    </xsl:template>
</xsl:stylesheet>

转换后的 XML 应如下所示

<HealthStarRating>Health Star Rating Better - 72339</HealthStarRating>
<HealthStarRatingDIClaims>Health Star Rating DI/Claims HSR - Test 72339</HealthStarRatingDIClaims>
<Nutritions>
   <Instruction>
       Potassium contributes to normal functioning of the nervous system
    </Instruction>
</Nutritions>

基本上,XSLT 应该包含一个条件,该条件确定“描述”标签的值并获取“文本”标签的值并作为单独的属性输出

提前致谢

您可以使用以下 XSLT-1.0 模板。

第一步,它提取不带空格的“描述”并将其存储在变量中。
在第二步中,它检查描述是特定类型之一还是 <Others>。如果它是特定类型,它会从描述中派生元素名称。

<xsl:template match="claims">
    <xsl:variable name="elemName" select="translate(entity/description,' &#xa;&#xd;','')" />
    <xsl:choose>
        <xsl:when test="$elemName='HealthStar' or $elemName='DIClaims'">
            <xsl:element name="{$elemName}">
                <xsl:value-of select="normalize-space(Text)" />
            </xsl:element>
        </xsl:when>
        <xsl:otherwise>
            <Others><xsl:value-of select="normalize-space(Text)" /></Others>
        </xsl:otherwise>
    </xsl:choose>
</xsl:template>

它的输出符合要求。
