XSLT：如何在单个XML中实现多循环元素

时间：2016-07-18 09:47:12

标签： xml xslt xslt-2.0

我们有输入XML。在那，我们想要多循环两个标签。这些标签是StockLine和CommentLine。我们必须以某种方式将两者结合在一起。当StockLine为null时，则CommentLine，否则当CommentLine为null时为StockLine。

在这种情况下： 我们共有9行商品7 stockLine和2 CommentLine。

输入XML：

我们尝试过XSLT： 

<xsl:stylesheet version="2.0" 
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="xml" encoding="Windows-1252" indent="yes"/>

        <xsl:template match="@xsi:nil[.='true']" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/>
    <xsl:template match="@*|node()">
        <xsl:copy copy-namespaces="no">
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>
    <xsl:template match="CommentLine[OrderLineID = preceding-sibling::StockLine/OrderLineID and not(Comment)]"/>
    </xsl:stylesheet>

AFAICT，你想做的只是：

<xsl:stylesheet version="2.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>

<!-- identity transform -->
<xsl:template match="@*|node()">
    <xsl:copy>
        <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
</xsl:template>

<xsl:template match="StockLine[not(StockCode)]">
    <CommentLine>
        <Comment>
            <xsl:value-of select="some-unknown-node"/>
        </Comment>
        <xsl:copy-of select="OrderLineID"/>
    </CommentLine>
</xsl:template>

</xsl:stylesheet>

我无法确定Comment的价值来自哪里。
