本文介绍了XSLT 使用多个循环删除重复项的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我必须使用 XSLT 转换以下 XML.
I have to convert the below XML using the XSLT.
输入 XML 为
<document>
<item>
<ID>1000909090</ID>
<flex>
<attrGroupMany name="pageinfo">
<row>
<attrQualMany name="pageinput">
<value qual="en">User Intake</value>
</attrQualMany>
<attrGroupMany name="pagetype">
<row>
<attr name="pagemeasure">EXACT</attr>
<attrQualMany name="pagecontain">
<value qual="GR1">20</value>
<value qual="GR2">21</value>
</attrQualMany>
</row>
<row>
<attr name="pagemeasure">EXACT</attr>
<attrQualMany name="pagecontain">
<value qual="JH1">30</value>
<value qual="JH2">31</value>
</attrQualMany>
</row>
</attrGroupMany>
<attr name="pagestate">PREPARED</attr>
<attrQualMany name="pagewidth">
<value qual="OZ">10</value>
<value qual="AB">11</value>
</attrQualMany>
</row>
</attrGroupMany>
</flex>
</item>
</document>
XSLT 应该在每一行的 attrGroupMany= "pagetype" 内循环，并在 attrQualMany ="pagecontain" 内循环，然后在 attrQualMany= 内循环页面宽度".所以它变成了 2*2*2 次循环，也就是 8 次.
The XSLT should be looped inside attrGroupMany= "pagetype" for each row as well as loop inside attrQualMany ="pagecontain" and then loop inside attrQualMany="pagewidth". so it becomes 2*2*2 times loops which is 8 times.
输出应该是concat的
The output should be concat of
<xsl:value-of select="concat('PAGEDETAILSINFO','-',ancestor::item/id,../../attr[@name='pagestate'], '-', pagewidthValue ,'-', pagewidthuom, '-', attr[@name='pagemeasure'] , '-',pagecontainValue, '-', pagecontainUOM )"/>
预期输出应该是
<?xml version="1.0" encoding="UTF-8"?>
<CatalogItem>
<RelationshipData>
<Relationship>
<RelationType>PAGEDETAILSINFO</RelationType>
<RelatedItems count="8">
<RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-10-OZ-EXACT-20-GR1" />
<RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-11-AB-EXACT-20-GR1" />
<RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-10-OZ-EXACT-21-GR2" />
<RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-11-AB-EXACT-21-GR2" />
<RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-10-OZ-EXACT-30-JH1" />
<RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-11-AB-EXACT-30-JH1" />
<RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-10-OZ-EXACT-31-JH2" />
<RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-11-AB-EXACT-31-JH2" />
</RelatedItems>
</Relationship>
</RelationshipData>
</CatalogItem>
但是我在输出中得到重复的行并且计数增加了两倍.
But I am getting duplicate rows in the output as well as count is getting double.
实际输出低于这是不正确的.
Actual output is below which is incorrect.
<?xml version="1.0" encoding="UTF-8"?>
<CatalogItem>
<RelationshipData>
<Relationship>
<RelationType>PAGEDETAILSINFO</RelationType>
<RelatedItems count="16">
<RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-10-OZ-EXACT-20-GR1" />
<RelatedItem referenceKey="PAGEDETAILSINFO-1000909090-PREPARED-11-AB-EXACT-20-GR1" />

</RelationshipData>
</CatalogItem>
这里使用的XSLT是
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output indent="yes" />
<xsl:template match="document">
<xsl:for-each select="item">
<xsl:variable name="item" select="." />
<xsl:variable name="pageinfo" select="flex//attrGroupMany[@name = 'pageinfo']/row" />
<xsl:variable name="pagetype" select="flex//attrGroupMany[@name = 'pagetype']/row" />
<xsl:variable name="pagecontain" select="$pagetype/attrQualMany[@name = 'pagecontain']/value" />
<xsl:variable name="pagewidth" select="flex//attrQualMany[@name = 'pagewidth']/value" />
<CatalogItem>
<RelationshipData>
<Relationship>
<RelationType>PAGEDETAILSINFO</RelationType>
<RelatedItems count="{count($pagetype) * count($pagewidth) * count($pagecontain) }">
<xsl:for-each select="$pagetype">
<xsl:variable name="t" select="." />
<xsl:for-each select="$pagecontain">
<xsl:variable name="p" select="." />
<xsl:for-each select="$pagewidth">
<xsl:variable name="w" select="." />
<RelatedItem referenceKey="PAGEDETAILSINFO-{$item/ID}-{$pageinfo/attr[@name='pagestate']}-{$w}-{$w/@qual}-{$t/attr[@name='pagemeasure']}-{$p}-{$p/@qual}" />
</xsl:for-each>
</xsl:for-each>
</xsl:for-each>
</RelatedItems>
</Relationship>
</RelationshipData>
</CatalogItem>
</xsl:for-each >
</xsl:template>
</xsl:stylesheet>
请帮忙删除重复项
推荐答案
你可以使用这个:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="xml" indent="yes" />
<xsl:template match="/document">
<CatalogItem>
<RelationshipData>
<Relationship>
<RelationType>PAGEDETAILSINFO</RelationType>
<xsl:variable name="pagetype" select="//attrGroupMany[@name = 'pagetype']/row"/>
<xsl:variable name="pagecontain" select="$pagetype//attrQualMany[@name='pagecontain']"/>
<xsl:variable name="pagewidth" select="//attrQualMany[@name = 'pagewidth']/value"/>
<RelatedItems count="{count($pagetype) * count($pagecontain) * count($pagewidth)}">
<xsl:for-each select="$pagetype">
<xsl:variable name="attr" select="attr[@name='pagemeasure']"/>
<xsl:for-each select=".//attrQualMany[@name='pagecontain']/value">
<xsl:variable name="value" select="."/>
<xsl:for-each select="$pagewidth">
<RelatedItem referenceKey="{concat('PAGEDETAILSINFO','-',ancestor::item/ID,'-',../../attr[@name='pagestate'], '-', . ,'-', @qual, '-', $attr , '-',$value, '-', $value/@qual)}"/>
</xsl:for-each>
</xsl:for-each>
</xsl:for-each>
</RelatedItems>
</Relationship>
</RelationshipData>
</CatalogItem>
</xsl:template>
</xsl:stylesheet>
