转换成以下输出格式。

在其他人的帮助下,我可以编写以下 xslt 来进行这种转换。
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:x="http://ws.wso2.org/dataservice" xmlns="http://ws.wso2.org/dataservice"
exclude-result-prefixes="x" version="1.0">
<xsl:output indent="yes" method="xml" />
<!-- Identity Transform -->
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()" />
</xsl:copy>
</xsl:template>
<xsl:template match="x:Standard">
<Product>
<xsl:copy-of select="x:ProductID" />
<xsl:copy-of select="x:Prefix" />
<xsl:copy-of select="x:SNumber" />
<xsl:copy-of select="x:Year" />
<xsl:copy-of select="x:Designation" />
<xsl:copy-of select="x:Publisher" />
<RelatedProducts>
<xsl:apply-templates select=".//x:RelatedProduct" />
</RelatedProducts>
<xsl:copy-of select="x:ProductICSCodes" />
<xsl:copy-of select="x:ProductDescriptions" />
<xsl:copy-of select="x:IndustryCodes" />
<xsl:copy-of select="x:ProductAttributes" />
<xsl:copy-of select="x:ProductReconfirmationNotices" />
<xsl:copy-of select="x:Type" />
<xsl:copy-of select="x:SaleItems" />
<xsl:copy-of select="x:Committee" />
<xsl:copy-of select="x:CommentClosesDate" />
<xsl:copy-of select="x:Note" />
<xsl:copy-of select="x:InternalNote" />

<xsl:copy-of select="x:Status" />
<xsl:copy-of select="x:State" />
<xsl:copy-of select="x:UpdateNote" />
<xsl:copy-of select="x:ThumbnailPath" />
<xsl:copy-of select="x:SortOrder" />
<xsl:copy-of select="x:EntryDate" />
<xsl:copy-of select="x:ExpiryDate" />
<xsl:copy-of select="x:SupersededDate" />
<xsl:copy-of select="x:UpdateDate" />
<xsl:copy-of select="x:WithdrawnDate" />
<xsl:copy-of select="x:PluginName" />
<xsl:copy-of select="x:S1" />
<xsl:copy-of select="x:S2" />

<xsl:copy-of select="x:S10" />
<xsl:copy-of select="x:HasLexConnect" />
<xsl:copy-of select="x:HasCodeConnect" />
</Product>
</xsl:template>
<xsl:template match="x:RelatedProduct">
<xsl:copy>
<xsl:apply-templates select="@*|*[not(name()='RelationId')]" />
<RelationType>
<xsl:value-of select="name(..)" />
</RelationType>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
现在我需要将根元素重命名为 Products 而不是 Standards 并从输出中消除所有 nil 值。 nil 值具有以下格式。
<Designation xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:nil="true"/>
<Abstract xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:nil="true"/>
<History xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:nil="true"/>
<TOC xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:nil="true"/>
我添加了以下 xslt 段,将根元素重命名为 Products。
<xsl:template match="x:Standards">
<Products namespace="{namespace-uri()}">
<xsl:apply-templates select=".//x:Standard" />
</Products>
</xsl:template>
正确吗?如何更改上述 xslt 以消除输出中的所有 nil 值。任何帮助将不胜感激。
【问题讨论】:
-
“正确吗” -- 它是否产生了您期望的输出?您不必通过在此处提问来检查每项更改。试试吧!至于用
xsi:nil="true"消除值,你知道如何为此编写一个匹配的模板,只需将模板设为空即可。 -
我得到了预期的输出。但我还不能消除那个 nil 值。
