XSLT 范围问题？

Question

正在使用新信息更新此 post。我附上了整个 XSLT，因为它相当复杂，而且我不完全确定要保留什么以保持问题的完整性和原因。此外，我将尽可能减少输入，以保持数据的完整性。我不包括的是 EDI X12 856 的 xsd。这是专有的，它也非常大。如果您使用的是 Biztalk EDI，则您已经拥有必要的架构。如果我可以从此架构中提供有助于回答此问题的信息，请告诉我，我会 post 满足您的任何需求。如果有什么地方我可以把 .xsd 放在存储库或电子邮件中，请告诉我。

问题是我试图接触到 LIN/LIN11 元素并将每次迭代的内容放入 DTM02 元素中。我要么缺少执行此操作的语法，要么我可能需要一些全局变量来遍历实例。但对于 XSLT 及其处理来说确实是新手。真的可以使用一些方向和解决方案会很棒。

Answer 1

当 HL03 = 'T' 时，您的 XSLT 仅输出 DTM 个节点，但您的输入文档只有 LIN/LIN11，其中 HL03是别的东西 (I).

如果想在没有LIN11的情况下不输出DTM节点，可以这样：

<!--Pack-->
<xsl:if test="ns0:HL/HL03 = 'T'">
    <xsl:element name="ns0:HLLoop1">
        <xsl:element name="ns0:HL">
            <xsl:element name="HL01">
                <xsl:value-of select="userCSharp:ReturnHL01('T')" />
            </xsl:element>
            <xsl:element name="HL02">
                <xsl:value-of select="userCSharp:ReturnHL02('O')" />
            </xsl:element>
            <xsl:element name="HL03">T</xsl:element>
        </xsl:element>
        <xsl:element name="ns0:MAN">
            <xsl:element name="MAN01">GM</xsl:element>
            <xsl:element name="MAN02">
                <xsl:value-of select="ns0:MAN/MAN02" />
            </xsl:element>
        </xsl:element>
        <!--End of MAN-->
        <xsl:if test="ns0:LIN/LIN11">
            <xsl:element name="ns0:DTM_2">
                <xsl:element name="DTM01">036</xsl:element>
                <xsl:element name="DTM02">
                    <xsl:value-of select="ns0:LIN/LIN11"/>
                </xsl:element>
            </xsl:element>
        </xsl:if>
    </xsl:element>
    <!--End of HLLoop1 Pack-->
</xsl:if>

如果你需要下面的LIN11节点，你可以使用这样的代码：

<xsl:element name="DTM02">
    <xsl:value-of select="following::LIN11[1]"/>
</xsl:element>

但这似乎很可疑并且容易被破坏（如果没有跟随 LIN11 怎么办，如果它是 10 个 HL 循环并被多次重复使用怎么办，等等...）。您可能最好获得具有 HL03 = 'I' 的 following HL 循环，也许使用类似此处 XSLT: Loop selecting two elements at a time

XSLT 范围问题？
