XSLT 1.0带条件的嵌套循环

我有一个输入XML，其中包含标头，后跟3个详细信息。然后是第二个标题，后跟1个详细信息。

此处的预期输出是2个单独的标题。 批处理名称为[001]的第一个标头具有3个DETAILS。 批处理名称为[002]的第二个标头具有1个DETAILS。 每个批次的DETAIL映射都应继续，直到结束指示符=9。

在使用endindicator = 9映射细节之后，下一个标头映射将从另一组DETAIL开始。

是否有任何想通过XSL 1.0实现此目标？

输入XML如下

<DETAILHEADER>
  <BatchNumber>001</BatchNumber>
  <BatchItemNumber>0011</BatchItemNumber>
</DETAILHEADER>
<DETAILITEM>
  <SequenceNumber>01</SequenceNumber>
  <EndIndicator>7</EndIndicator>
<DETAILITEM>
  <SequenceNumber>02</SequenceNumber>
  <EndIndicator>7</EndIndicator>
</DETAILITEM>
<DETAILITEM>
  <SequenceNumber>03</SequenceNumber>
  <EndIndicator>9</EndIndicator>
</DETAILITEM>
<DETAILHEADER>
  <BatchNumber>002</BatchNumber> 
  <BatchItemNumber>0022</BatchItemNumber>
</DETAILHEADER>         
<DETAILITEM>
  <SequenceNumber>01</SequenceNumber>
  <EndIndicator>9</EndIndicator>
</DETAILITEM>

预期输出

<tns:HEADER>
  <BatchNumber>001</BatchNumber> 
  <tns:DETAIL>
    <SequenceNumber>01</SequenceNumber>
  <tns:DETAIL>
    <SequenceNumber>02</SequenceNumber> 
  </tns:DETAIL>
  <tns:DETAIL>
    <SequenceNumber>03</SequenceNumber> 
  </tns:DETAIL>
</tns:HEADER>
<tns:HEADER>
  <BatchNumber>002</BatchNumber> 
  <tns:DETAIL>
    <SequenceNumber>01</SequenceNumber>
  </tns:DETAIL>
</tns:HEADER>

我认为这里的问题仍然没有解决-仍然有问题 让我更清楚我的数据 原始输入：

<xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="body">

这是预期的输出-tns名称空间可以忽略

此处错误地重复了每个标题的详细信息
当前代码如下

<xsl:template match="/">
<tns:HEADERLP>
<xsl:for-each select="/ns0:CA/ns0:DETAILHEADER">
<tns:HEADER>
<tns:BatchName>
<xsl:value-of select="ns0:BatchNumber"/>
</tns:BatchName>
<tns:ItemNumber>
<xsl:value-of select="ns0:BatchItemNumber"/>
</tns:ItemNumber>
<tns:CustomerNumber>
<xsl:value-of select="ns0:Destination"/>
</tns:CustomerNumber>
<tns:CheckNumber>
<xsl:value-of select="/ns0:CA/ns0:RECORD6/ns0:CheckNumber"/>
</tns:CheckNumber>
<xsl:for-each select="/ns0:CA/ns0:DETAILITEM">
<tns:Detail>
<tns:BatchName>
<xsl:value-of select="ns0:BatchNumber"/>
</tns:BatchName>
<tns:ItemNumber>
<xsl:value-of select="ns0:BatchItemNumber"/>
</tns:ItemNumber>
<tns:SequenceNumber>
<xsl:value-of select="ns0:SequenceNumber"/>
</tns:SequenceNumber>
</tns:Detail>
</xsl:for-each>
</tns:HEADER>
</xsl:for-each>
</tns:HEADERLP>
</xsl:template>
</xsl:stylesheet>

基本上，只需要为相应的批号映射详细信息，并且在DETAILITEM内的endindicator = 9之后，映射应停止。

如何使用XSL 1.0版实现此目标？

2 个答案:

答案 0 :(得分：0)

对于xsl 2.0，您可以使用xsl:for-each-group。您可以使用group-starting-with

样式表如下：

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:tns="www.tns.com"
    exclude-result-prefixes="tns"
    version="2.0">

    <xsl:strip-space elements="*"/>
    <xsl:output indent="yes"/>

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

    <xsl:template match="root">
        <xsl:copy>
            <xsl:for-each-group select="*" group-starting-with="DETAILHEADER">
                <tns:HEADER>
                    <xsl:apply-templates select="current-group()"/>
                </tns:HEADER>
            </xsl:for-each-group>
        </xsl:copy>
    </xsl:template>

    <xsl:template match="DETAILHEADER">
        <xsl:apply-templates/>
    </xsl:template>

    <xsl:template match="DETAILITEM">
        <tns:DETAIL>
            <xsl:apply-templates/>
        </tns:DETAIL>
    </xsl:template>

</xsl:stylesheet>

我已调整您的输入XML以使其格式正确。在操作here中查看它。

XSLT 1.0

您可以使用generate-id()函数来应用具有与第一个前一个DETAILHEADER节点相同的ID的后继兄弟姐妹

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:tns="www.tns.com"
    exclude-result-prefixes="tns"
    version="1.0">

    <xsl:strip-space elements="*"/>
    <xsl:output indent="yes"/>

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

    <xsl:template match="root">
        <xsl:copy>
            <xsl:for-each select="DETAILHEADER">
                <xsl:variable name="ID" select="generate-id()"/>
                <tns:HEADER>
                    <xsl:apply-templates/>
                    <xsl:apply-templates select="following-sibling::DETAILITEM[preceding-sibling::DETAILHEADER[1][generate-id()=$ID]]"/>
                </tns:HEADER>
            </xsl:for-each>
        </xsl:copy>
    </xsl:template>

    <xsl:template match="DETAILITEM">
        <tns:DETAIL>
            <xsl:apply-templates select="SequenceNumber"/>
        </tns:DETAIL>
    </xsl:template>

</xsl:stylesheet>

答案 1 :(得分：0)

我建议您采用这种方式（假设一个root根元素，并忽略预期输出上未绑定的tns:前缀）；

XSLT 1.0 

<xsl:stylesheet version="1.0" 
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="*"/>

<xsl:key name="item" match="DETAILITEM" use="generate-id(preceding-sibling::DETAILHEADER[1])" />

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

<xsl:template match="/root">
    <xsl:copy>
        <xsl:apply-templates select="DETAILHEADER"/>
    </xsl:copy>
</xsl:template>

<xsl:template match="DETAILHEADER">
    <HEADER>
        <xsl:apply-templates/>
        <xsl:apply-templates select="key('item', generate-id())"/>
    </HEADER>
</xsl:template>

<xsl:template match="DETAILITEM">
    <DETAIL>
        <xsl:apply-templates select="SequenceNumber"/>
    </DETAIL>
</xsl:template>

</xsl:stylesheet>
