for-each分割记录

Question

我不确定这是否可能，但我们开始吧。

有一个xml文件:

,我想使用下面的逻辑拆分从它返回的记录:

如果xml文件有30个或更多的prove -or- clm -or- totalals节点，则只处理30个prove -or- clm -or- totalals节点。如果剩余节点数少于30，则对整个xml文件执行此操作，处理它们以完成转换

我使用下面的xsl来完成:

Kamza，你有一部分是对的，但是你的方法有一些缺陷。首先在PROV元素上使用for-each语句，在for-each语句中使用if语句，使输出仅针对PROV元素1、31、61等进行编写。嵌套的for-each循环也有类似的问题。只有CLM元素1,31,61，…

(实际上，我怀疑在每个PROV中只会有一个TOTALS，因此在您的代码中可以。)

此外，从我从你的描述和评论中理解的是，你试图一次写出30行，并在那之后开始一个新的表，甚至一个新的页面，还有另外30行，或者剩下的。因为没有为PROV元素本身写入行，所以我假设它只是关于CLM和TOTALS行，其中计数30应该包括这两行。

您需要的是一个外部的for-each循环，它遍历所有CLM和TOTALS元素。你可以使用这个表达式:

    <xsl:for-each select="ROOT/MEM-STMT/ACC/PROV/*[self::CLM or self::TOTALS]">

如果你已经创建了一个新的表，第1,31,61，…

要用前30项填充表，您需要向前查找30个位置。在这里，PROV元素有点问题。假设CLM和TOTALS只出现在PROV中，并且PROV没有在其他地方使用，那么您可以合理安全地使用以下轴:

    <xsl:for-each select="(following::*[self::CLM or self::TOTALS])[30 >= position()]">

返回30项，CLM和TOTALS混合在一起，但按文档顺序排列。您需要两个额外的if(或一个选择)来区分这两者，并输出适当的表行:

    <xsl:if test="self::CLM">
        ...
    </xsl:if>
    <xsl:if test="self::TOTALS">
        ...
    </xsl:if>

在您的代码中，您必须在内部for-each循环中使用:table-body，导致每个表行都被包装在一个新的表体中。这是不必要的。将表体移动到内循环的外部。您只需要对CLM和TOTALS行进行一次包装。

最后，为每30个项目编写一个新表。我认为你也需要重新开始一个页面序列。这将导致每个表显示在单独的页面上。把这些放在一起，您会得到一个类似于这样的XSLT:

注意:我不完全相信这会阻止你得到一个异常。你给人的印象是这是因为你的for-each循环，但它可能是由其他原因引起的。例如，表太大或者文档太大而无法呈现也可能是原因。上面的代码应该相当高效。如果它仍然给您带来麻烦，请尝试从命令行处理，甚至可能使用不同的解析器。

Answer 2

…我没有时间详细查看xslt，但是您的逻辑应该可以使用如下内容:

<xsl:template match="(//PROV | //CLM | //TOTALS)[position() <= 30]">
   <xsl:if test="local-name() = 'PROV'">
       <!-- do stuff with PROV node -->
   </xsl:if>
   <xsl:if test="local-name() = 'CLM'">
       <!-- do stuff with CLM node -->
   </xsl:if>
   <xsl:if test="local-name() = 'TOTALS'">
       <!-- do stuff with TOTALS node -->
   </xsl:if>
</xsl:template>

Answer 3

您可以修改xsl:for-each语句，将它们限制为前30个条目:

<xsl:for-each select="ROOT/MEM-STMT/ACC/PROV[position()&lt;=30]">

或者您可以将xsl:for-each逻辑提取到模板中，然后只选择前30个来应用模板:

<xsl:apply-templates select="ROOT/MEM-STMT/ACC/PROV[position()&lt;=30]"/>
