Question

下面是我的输入 XML。这里每个 X_DLV_TAB_ITEM 都有多个 RL_DETAILS，而这些 RL_DETAILS 又有多个 RL_DETAILS_ITEM。每个 RL_DETAILS_ITEM 包含 SOURCE_HEADER_NUMBER。

我的要求是，如果两个或多个 X_DLV_TAB_ITEM 的 SOURCE_HEADER_NUMBER 相同，则只应创建 X_DLV_TAB_ITEM ，它将包含第一个 X_DLV_TAB_ITEM 以及其他的所有 RL_DETAILS_ITEM。

请帮帮我，我一直在努力解决这个问题。PS：我使用的是 XSLT 1.0

谢谢阿杰

钥匙是你强大的朋友：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

    <!-- key over all first X_DLV_TAB_ITEM by source -->
    <xsl:key name="first_of_source" match="X_DLV_TAB/X_DLV_TAB_ITEM[not(preceding-sibling::X_DLV_TAB_ITEM/RL_DETAILS/RL_DETAILS_ITEM/SOURCE_HEADER_NUMBER = RL_DETAILS/RL_DETAILS_ITEM/SOURCE_HEADER_NUMBER)]" use="RL_DETAILS/RL_DETAILS_ITEM/SOURCE_HEADER_NUMBER"/>
    <!-- key over all RL_DETAILS by source -->
    <xsl:key name="same_source" match="X_DLV_TAB/X_DLV_TAB_ITEM/RL_DETAILS" use="RL_DETAILS_ITEM/SOURCE_HEADER_NUMBER"/>


    <!-- just copy all nodes by default -->
    <xsl:template match="@* | node()">
        <xsl:copy>
            <xsl:apply-templates select="@* | node()"/>
        </xsl:copy>
    </xsl:template>

    <!-- process only the first tab item with a specific source -->
    <xsl:template match="X_DLV_TAB">
        <xsl:copy>
            <xsl:apply-templates select="key('first_of_source', X_DLV_TAB_ITEM/RL_DETAILS/RL_DETAILS_ITEM/SOURCE_HEADER_NUMBER)"/>
        </xsl:copy>
    </xsl:template>

    <!-- process details with all detail items having the same source -->
    <xsl:template match="RL_DETAILS">
        <xsl:copy>
            <xsl:apply-templates select="key('same_source', RL_DETAILS_ITEM/SOURCE_HEADER_NUMBER)/RL_DETAILS_ITEM"/>
        </xsl:copy>
    </xsl:template>
