我在查找如何通过for循环中的子节点进行分组时遇到了一些麻烦。起始XML看起来像这样(省略了一些节点):
<Report>
<LAC_SalesOrderId>
<APL>
<LAC_Customer>09680001</LAC_Customer>
</APL>
<Detail>
<LACRecId_DONOT_CHANGE_Textbox169>5637144820</LACRecId_DONOT_CHANGE_Textbox169>
<LAC_MarkupTransLines>
<MarkupTrans>
<Detail_Collection>
<Detail>
<MarkupTrans_Detail>

到目前为止,我有这个XSLT:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:key name="groups" match="//FIELD_MarkupTrans_MarkupCode" use="."/>
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="//LAC_MarkupTransLines/MarkupTrans/Detail_Collection">
<Detail_Collection>
<xsl:apply-templates select="Detail/MarkupTrans_Detail/FIELD_MarkupTrans_MarkupCode[generate-id() = generate-id(key('groups', .)[1])]"/>
</Detail_Collection>
</xsl:template>
<xsl:template match="FIELD_MarkupTrans_MarkupCode">
<xsl:variable name="currentGroup" select="."/>
<MarkupCode>
<xsl:copy-of select="../FIELD_MarkupTrans_MarkupCode"/>
<xsl:for-each select="key('groups', $currentGroup)">
<xsl:copy-of select="../.."/>
</xsl:for-each>
</MarkupCode>
</xsl:template>
</xsl:stylesheet>
问题是所有MarkupTrans_Detail节点都在第一个LAC_SalesOrderId下分组,但我需要它们由每个LAC_SalesOrderId分割。我相信我错过了一些明显的东西,并希望有人可以帮助我解决这个问题:)
答案 0 :(得分:0)
以这种方式尝试:
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="grp" match="MarkupTrans_Detail" use="concat(FIELD_MarkupTrans_MarkupCode, '|', generate-id(ancestor::LAC_SalesOrderId))"/>
<!-- identity transform -->
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="Detail_Collection">
<xsl:copy>
<xsl:for-each select="Detail//MarkupTrans_Detail[generate-id() = generate-id(key('grp', concat(FIELD_MarkupTrans_MarkupCode, '|', generate-id(ancestor::LAC_SalesOrderId)))[1])]">
<MarkupCode>
<Code>
<xsl:value-of select="FIELD_MarkupTrans_MarkupCode"/>
</Code>
<xsl:apply-templates select="key('grp', concat(FIELD_MarkupTrans_MarkupCode, '|', generate-id(ancestor::LAC_SalesOrderId)))"/>
</MarkupCode>
</xsl:for-each>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
应用于您的输入示例,结果将是:
